Throughout this Fluval 307 vs Marineland 360 comparison, I’ll go over the technical specifications and features of both canister filters so you can determine the best fit for your aquarium setup.

Fluval 307 vs Marineland 360 – Key Information

Here’s a brief overview that covers all the essential features of both filters.

You may notice my tank size suitability figures differ slightly from what Fluval and Marineland state. I’ve done a chart further down explaining how I work this out.

If you’re asking me which I’d buy, I’d go with the Fluval every time. I’ve used them for years and have always found them well-built and ultra-reliable.

The 307 is easier to set up than the Magniflow 360, cheaper to run, and is quieter. I’ve gone over some of the gripes with the Marineland further down this post.

What Size Canister Filter Do I Need?

A general rule of thumb is that you want the pump output (gallons per hour) to be 5 times the size of your tank, so multiply the size of your tank by 5 to find out the g/ph that is ideal.

I’ve found that following this simple calculation stops you from buying a filter that is too small or too large (and wasting money) for your aquarium.

If you have an overstocked stocked tank that has a large bioload, it’s recommended that you multiply your tank size in gallons by 10, to find a suitable turnover rate for your tank.

Since there is no standardized calculation used by all the different manufacturers, each manufacturer may suggest a different tank size suitability for their ‘XXX g/ph’ filter.

By using this formula, you can compare filters from different manufacturers on an equal basis.

20 100 g/ph 200 g/ph
29 145 g/ph 290 g/ph
40 200 g/ph 400 g/ph
55 275 g/ph 550 g/ph
75 375 g/ph 750 g/ph
90 450 g/ph 900 g/ph
100 500 g/ph 1000 g/ph

Most manufacturers state the g/ph when the filter is empty with no media in place. 

Once the media is in place (and it’s got gunked up after a while!), these g/ph figures reduce drastically and the real-world turnover rate will probably be around 50% less. 

Nonetheless, I’ve found that the filtration based on this calculation is more than adequate.

Fluval 307 or Marineland 360: Detailed Comparison

Now for those of you who like to know every last detail, grab yourself a coffee and get comfortable, we’ll dive into all the differences.

I’ll also cover how to set up and maintain these filters, as no one wants a filter that’s a pain in the butt to maintain.

Tank Size

Fluval 307 is suitable for aquariums of up to 60 gallons.

Marineland Magniflow 360 is suitable for aquariums of up to 70 gallons.

The 07 series of Fluval canister filters also have smaller and larger filters available the Fluval 107, 207, and 407.

The Marienland Maginflow has smaller options in the 160 and the 220.

Type Of Fish You Keep

Different fish require different levels of filtration. Some fish are particularly messy so you need to make sure your filter can cope with them. 

I’ll list a few common messy fish and if you keep any of these guys you may be best choosing a larger filter that has more capacity for filter media to catch the additional mess, keeping your water clean and clear.

Bristlenosed Pleco – Although these guys are part of a tank’s clean-up crew and do a great job of eating algae and leftover food, all that algae and food have to come out the other end!

Cichlids – In particular large cichlids like Oscars, who are known to rip up plants, stir up the substrate, and even re-arrange rocks, all creating lots of mess.

Goldfish – These guys love to dig around and stir up the substrate and are known for pooping a lot, so you need a filter that can cope.

Turtle – If you keep a turtle rather than fish in your aquarium, you may need a much more powerful filter to deal with the amount of waste they produce, check out my turtle filter guide for more info.

Freshwater and Saltwater Compatibility

Both the Fluval 307 and Marineland 360 are designed to work in freshwater and saltwater aquariums.

Filter Media

Both filters come with all the filter media you need which includes all 3 stages of filtration.

Mechanical Filtration Media

Mechanical media catches all of the debris in the water, if you’ve got loads of stuff floating around in the water, it’s time to rinse out those filter pads!

Biological Filtration Media

Biological filtration uses beneficial bacteria to consume highly toxic ammonia and nitrites, turning it into safer nitrate, which you then reduce with water changes and by having live plants.

Ceramic rings and bio balls provide valuable extra surface area for beneficial bacteria to colonize, aiding in breaking down these harmful toxins, and keeping your nitrogen cycle in check, helping keep the water safe for your fish.

Chemical Filtration Media

Activated carbon helps remove chemical impurities, odors, and discoloration from the water, keeping it crystal clear and smelling sweet, no one wants their tank to smell like rotten eggs!

Activated carbon needs to be replaced regularly as it will stop working, aim to replace it after a month.

Important: Carbon also removes medications, so remove all activated carbon filter media when treating your fish with medication.

The Fluval 307 comes with the following filter media:

The Marineland 360 comes with the following:

Marineland Magniflow 360 Filter Media

Where the Fluval 307 really sets itself apart from the Marineland is the option of customizing the media within the filter with the optional ammonia, nitrite, and phosphate pads.

Fluval Nitrite Pads

The ammonia and nitrite pads help the Fluval 07 series canister filters cycle new tanks faster and keep heavily stocked tanks safer, helping prevent fish loss.

Setting Up The Fluval 307

The Fluval 307 is an absolute breeze to set up. 

I’ll also include a video as sometimes it’s just easier to watch than read an explanation.

Although it arrives assembled, you have to take it all apart as there’s a leaflet inside the canister, the filter media comes sealed in plastic bags, as does the rubber gasket seal that goes between the canister and lid.

Give all the filter media a rinse before using it, you don’t want any bits of dust getting pumped into your tank.

Fitting all back together is child’s play. Inside the canister are tracks molded into the sides to form different compartments.

The filter media baskets and frame that hold the Bio-foam and Bio-foam Max pads will only fit back inside one way.

TOP TIP: When you’ve put the Bio-foam+ and quick clear pads back in the bottom tray put the red lifting handle through the basket at this point.

It’s much easier to stack the rest of the baskets on top of each other with the handle in place rather than inserting the handle once you’ve stacked the baskets on top of each other.

Install the rubber gasket on the filter lid.

Like the baskets, the canister lid will only fit one way too. The 307 badge on the front of the lid fits into a notch molded into the rim of the canister body.

The hose clamps do a great job of keeping the intake and output hoses in place.

When it comes to fitting the hose clamps to your tank, all I’ll say is: read the instructions first. I’m a typical guy, instruction manuals must not be read at all costs, I will struggle and tear my hair out first!!

Basically, the fittings have 2 parts: the clamp that fits onto the tank and the cover that secures the piping in place.

The covers need to be fitted vertically. The rear part of the clamp and the pipe cover slide together using tongue and groove moldings. The underside of the curved part of the cover then clips onto the curved part of the clamp.

Aquastop Valve

Fluval 307 AquaStop Valve

The Aquastop valve is a key feature of the entire 07 canister filter range.

This valve allows you to stop the water flow and then detach it from the filter in one piece, making cleaning and maintenance way easier.

To install the Aquastop valve:

  1. Place the Aqua stop valve on the inlet and outlet ports on the top of your canister filter and press the red lever down to lock it in position.

  2. Lift the grey lever up so it’s vertical to put the valve in the OFF position.


Place the filter on a flat and sturdy surface, beneath your fish tank.

Canister filters are ‘gravity fed’ so they need to be below the tank for them to work correctly. If you put a canister filter at the side of a tank, the top of the filter must be below the surface of the water, but it can be tricky to get the filter working efficiently.

Position the filter as close to your aquarium as you can and avoid any sharp bends or turns in the tubing.

Fit The Tubing

The intake and output hose is supplied in a single length that you have to cut yourself.

To avoid miscutting my pipe the wrong length (come on, we’ve all done it!) I find it easier to attach both ends of the pipe to the valves at this point, then cut it once I know it will reach over the top of the tank and back into the water.

If you do miscut the tubing, it’s not the end of the world, you can get a replacement length of tubing.

Fluval 307 Ribbed Hosing

You’ll need to take into account the length of the intake assembly when trimming the intake pipe which is 10.5” (26.5cm)

The Aquastop valve is clearly marked which side is the intake and outlet so you can’t get this wrong.

The output nozzle does a decent job itself, but you can add the Fluval Spray Bar Kit, to help eliminate surface scum and aerate the water.

Fluval Spray Bar Kit


To prime the pump: 

  1. Make sure your output nozzle is above the water’s surface so it has access to air.

  2. Press the grey lever on the Aquastop valve downwards so it sits on top of the red lever.

  3. Move the priming handle up and down 3 or 4 times until you can hear the filter filling itself with water.

Once the canister filter has filled with water, plug it into the mains power and you should have water flowing out of the outlet nozzle.

That’s it, the Fluval 307 is now set up and good to go.

Setting Up The Marineland Magniflow 360

This is my biggest gripe with this filter. It’s a little frustrating to set up.

Like the Fluval 307, it arrives ready assembled, but you’ve got to take it all apart as the filter media comes in plastic bags.

As does the canister, the water valves, the O ring gasket, the tubing, intake and output assemblies, etc. Why use so much throw-away plastic in this day and age?

As always, rinse the filter media under your tap as they can get a little dusty during shipping.

The media trays are the same shape as the canister opening. But, you’ll notice that they have an arrow on the handle.

Marineland Stack-N-Flo Media Tray

When you put the trays back into the canister, make sure the arrow lines up with the arrow on the tab on the filter case.

Fit the O Ring to the filter lid. This isn’t mentioned clearly in the assembly instructions for some reason – It is mentioned on the back of the green parts leaflet, but could easily be missed!

Fill the canister with dechlorinated water or tank water. This step is optional, but if you do this, you’ll have an easier time priming the filter.

Fit the canister lid.

Valve Block

Marineland Valve Block

Next up, fit the valves. I had a little trouble getting these things to stay in place at first.

The valve has 2 levers, 1 red and 1 black. To install it:

  1. Start with both levers in a vertical position and turn the red lever counterclockwise.

  2. Press the valves onto the filter, turn the red lever clockwise, then press it down.

  3. Now press the black lever downwards.


As with the 307, place the filter as close to your aquarium as you can, making sure it’s on a flat and sturdy surface, preferably beneath your fish tank.

Fit The Tubing

Marineland Magniflow Tubing

The hoses come in 2 separate 6-foot pieces and aren’t the easiest to work with, in fact, you’d think they have a mind of their own sometimes! 

Soaking them in hot water for 10 minutes helps to make them more workable.

Attaching the hoses to your intake and output assemblies is simple enough, just push the hose up to where it needs to go and fasten the snapper clamp in place to hold it together.

Fit the intake and outputs to the tank with the suction cups which do a decent enough job.

The snapper clamps I’m not a fan of either. I had to use a pair of pliers to get them tight enough as they made my fingers sore squeezing them together.

You have to have the snapper clamps fastened fully or your filter system won’t be air-tight which will mean it’s difficult to prime and won’t run at full efficiency.

You could get yourself some ⅝” hose clamps that you tighten with a screwdriver or hex-head driver to save your fingers.

LOKMAN 20 Pack Stainless Steel Hose Clamp

The water intake has a fixed length of 17 inches but can be trimmed to suit the depth of your tank if it’s too long.

Attaching them to the filter valves is simple enough, just push them on and screw up the red nut to hold the hose in place.

The intake and output valves are clearly marked which is which so you can’t get this wrong.


Priming the 360 is easy:

  1. Make sure your output nozzle is above the water’s surface so it has access to air.

  2.  Put both red and black levers on the valves in the downward position.

  3. Press the red prime button on top of the filter several times until it starts to draw water in from your tank. You have to keep pressing for quite a while sometimes.

Once the canister is full of water you can plug it in and you should have water coming out of the outlet nozzle.

I always recommend having a drip loop on all electrical items for your aquarium, we all know water and electricity are not a good match!

How To Set Up A Drip Loop

Filtration Performance

There’s nothing in it between the 2 when it comes to performance.

Both filters do a very good job of removing toxins and detritus, keeping the water parameters stable and the water crystal clear.

Maintenance and Cleaning

It is the same process for cleaning both Fluval 307 and Marineland 360, so I’m not going to do separate sections for each.

There’s no set answer for how often you should clean your filter. It differs from one aquarium to another and depends on many factors, mainly how many fish you have and how messy they are. 

Never use soaps or detergents to clean your filter or aquarium.

  1. Unplug from the main power, shut off the water flow by lifting the grey or black lever, then lift the red lever to disconnect the valves from the filter.

  2.  Put a towel and bucket on the floor and empty the water from the filter into the bucket (this will save you from having to dunk your hand in dirty fish poop water in the following step) you’ll then use this water to clean everything.

  3. Remove the filter lid.

  4. If you have the Fluval 307, the EZ-Lift media baskets can be removed with one finger using the red handle. If you have the Marineland, the Stack-N-Flo baskets need to be removed one at a time, which is why I empty the water out of the canister before opening it.

    Clean the mechanical filter media: Gently squeeze the sponge or coarse foam media in the bucket to remove larger debris and waste particles, you don’t need to get them spotless.

    Inspect and rinse the biological media: Check the ceramic rings and/or bio-balls for any accumulated debris and gently swish them in the same bucket to remove surface dirt.

    Replace the chemical filter media as needed: Chemical media has a limited lifespan and should be replaced according to the manufacturer’s recommendations or when you notice a decline in water quality.

    Top Tip: Use the water in the bucket that you rinsed all the filter media in to water your house plants or garden, your plants will love it!

  5. Clean the filter’s impeller and housing: Over time, debris and slime can accumulate in this area, resulting in reduced pump performance.

    Remove the impeller and gently clean it in the bucket and wipe out the housing where the impeller sits with a cloth.

  6. Clean the main body of the canister where the filters go: Add a bit of water and swish it around to loosen any brown sludge in the bottom and pour it into the bucket.

  7. Finally, using a bottle brush clean the input and output nozzles to remove any buildup or debris. These nozzles pull apart easily so you can get into all the nooks and crannies.

  8. Once everything has been cleaned, reassemble the media baskets, fit the lid, reconnect the valves and press the black or grey lever down. You will hear a flow of water as your filter re-fills (if you don’t hear water flowing, pump the primer a few times).

    Once your filter has filled up plug it back into the mains power.

    Top Tip: When you put the lid back on, push it down firmly all the way around before clipping the brackets in place, this ensures you have a nice tight water seal and avoids any leaks.

    You will need to lubricate the rubber o-ring occasionally using a
    silicone based lubricant.

Pump Performance and Efficiency

When you’re planning to upgrade to a new canister filter, the filter’s pump performance and energy consumption are important things to consider.

Pump Output and Circulation

The Fluval 307 has a filter circulation rate of 303 gallons per hour (1,150 L/h), making it suitable for aquariums of up to 60 gallons.

On the other hand, the Marineland 360 has a higher filter circulation rate of 360 Gal/h (1360 L/h), making it suitable for aquariums of up to 70 gallons.

The Fluval 307 has an adjustable flow rate so you can fine-tune the water flow to your fish’s needs. The Marineland 360 doesn’t have this feature.

Energy Efficiency

Fluval 307 vs Marineland 360 Energy Effieciency

With ever-rising energy prices, this has to be something to take into consideration.

The Fluval 307’s power consumption is 120V – 16 Watts / 230-240V – 15 Watts.

The Marineland 360’s power consumption is 120V – 35 Watts

As you can see, the Fluval 307 will cost less than half the amount to run as the Marineland 360.

The approximate annual running cost for each filter is:

  • Fluval 307, based on $0.15 per kWh = $21.04 per year.
  • Marineland 360, based on $0.15 per kWh = $46.02 per year.

Filter Noise

I’m really sensitive to background noises, the slightest little thing drives me nuts if I’m trying to read or watch TV.

  • The Fluval 307 comes in at 48 decibels
  • The Marineland 360 comes in at 55 decibels

Conclusion – Fluval 307 vs Marineland 360 Review

The Marineland 360 is a decent filter, but I’d choose the 307 every time.


  • It’s easier to set up
  • It’s easier to maintain
  • It’s quieter
  • It has an adjustable flow rate
  • It costs less to run each year
  • It’s reliable

Many complaints I see about the Marineland Magniflow filters are that they leak and are difficult to prime. Remember to:

  1. Fill the canister with water before refitting the lid

  2. Fit the rubber o-ring to the lid

  3. Make sure the snapper clamps are nipped up real tight (carefully use pliers if necessary)

This will help to eliminate these issues…or you could save yourself the hassle and get a Fluval instead!

If you were looking at the Marineland because you have a tank bigger than 60 gallons, which is the maximum tank size the Fluval 307 can handle, then I suggest you check out my Fluval 307 vs 407 comparison.
