I purchased the 220 for my 55 gal tank. It keeps the water clear but I have developed an oil film on top of the waterline. I was told I am not moving enough water to break it up. I just purchased the 530 just to be safe. I am going to use both filters to do the job. Its probably overkill but too much is better then not enough. Basically, I recommend using the next size up from the 220 or bigger for 55 gallons.

Keeps tank super clear and is super quiet.

Unbelievable how quiet the C-360 model is. I have been having dirty water issues with previous filters and finally gave in and bought the 360. So glad I did. As far as pricing goes for filters and media, Pet Mountain has best prices of all retailers - trust me, I've checked them all.

Very easy to install and wow it's very quiet. Maintenance will be a breeze with this, easy access to everything and no water spills to worry about. Been up and running for about 2 hours and the water is looking better already, i would definitely recommend this filter to anyone and buy it here because it's a lot better price here than anywhere else i could find. thanks pet mountain

I inherited two red ear slider turtles from my grand son. We could not keep the water clean for more than three days. I bought the 160 model because of our 29 gallon tank. Its been 9 days and counting with clear water and no smell. What a relief! Would give this filter an A-plus. Very easy to set up and has a cd with it also.

I have 2 c-220's on a 55gal with 260 assorted tetras in it. All water tests are great,no problems. Water crystal clear. Super easy to use and service. I am going to buy a c-360 that is going on a 40gal to be set up for discus and angels. This will be the fourth tank in the house and all use Marineland filters. For the price there just isn't any thing better!

This product works really good and is very quiet.

I have the 100 gal p/m filter. The filter has been running well for over a year. My son has 2 of these and has not had any problems for over 2 years.

C-360 2+ yrs old, worked great until last cleaning. I have reassembled 4 times cleaning O-ring groove, and added Vaseline to O-ring. It is now sitting in a 3 gallon wash-pan and dripping away as I TRY to dry carpet.

I purchased the C-360 here at pet mountain 2 years ago and here is my second review. The unit comes packed with goodies and ready to use. The unit is very easy to maintain and does a great job cleaning the water. Here are the faults: The hose is so stiff it makes it very difficult to mount them on the tank to get the desired placement of the fittings. The intake line is so long that you can not adjust to meet your tank unless the tank is a tall one 24". The final item is that the control valve fails and leaks unexpectedly and you will get a mess. You can try everything from doing the typical maintaining the seals to keeping the unit clean. IT DOES NOT WORK. The unit must sit in a bucket as an insurance or you will be sorry. Mine had leaked several times; now its out of warranty and you can't buy any parts.

I purchased the C-360 for my Red Ear Slider. He is in a 46 bowfront. His tank has never been so clean! I Recommend this canister to anyone who has a fish tank. I have others in the past, but this tops the bunch! I am so gald I found this site!!!

This is without a doubt the best canister filter you can purchase. I have C360 on a 75gal fresh-water tank with 10 small Koi. The water stays crystal clear. Easy to assemble, easy to clean. It's so quiet that you don't even realize it's on. My air pump is louder. It doesn't get any better.

This filter definately does the job. My 55 gallon African Cichlid tank has never been this clear and clean. This filter replaced 2 Penguin 200 bio-wheel hob filters that never got the tank this clean. It's literally dead quiet and worth every penny.

This filter is excellent.. also excellent price through pet mntn. I have 2 of them along with external filters on my 150 gal. and have great success.. thanks alot!!

We purchased a C-160 for supplementary filtration in our 24 gallon saltwater tank. Even without the optional "polishing filter pads" this cannister quickly clears up suspended debris, especially after cleaning the sand bottom. Built-in priming pump, quick-connect hose assembly and layered media trays make it so much easier to setup and maintain. Note that the C-160 only has THREE trays, so if you need four, go up one model! Also, the C-160 does not include ceramic rings (for biological filtration), although for our supplementary purpose this was not a problem, sized correctly this would make a great solo pump/filter unit for any aquarium. I'm told getting replacement parts is easy, but haven't had to do so yet.

Easy to setup and maintain. Measure and cut hosing before stating filter, its a mess if you want to resise it later. Also buy and extra polishing filter pad. After first cylcing it get dirty.

it's easy to use

On August 22, 2007:
I got the C360 for a 25 gal tank because the old filter would not keep the water clear. The water is now crystal clear with the C360 in service. Considering getting another unit for a total of two for a higher fish load.

I bought this to upgrade the filtration on my reef tank and it is very easy to use and set up for a first time canister user. It is powerful and silent, the instructions are very clear. I love changing to it from the bio wheel. It is easy to take apart and clean, love the flexibility of different media trays. If you are thinking of a canister filter I would recommend this one to anyone.

Marineland C360 is best canister filter for the price and function and comparable to Ehiem without the price tag. Very simple to use straight forward operation, the media basket nest tightly in the canister with very little to no bypass, prime button much better than Fluval, solid feeling not a stick with a suction cup on the end. Could use a drain valve on bottom of the canister to allow draining the canister to make it lighter and reduce a little splash of water when separating the valve block. In addition, a better method of securing the inlet and return assembly. The suction cup and weak plastic clip but tough to hold a hefty 3/4" hose with intake and return fittings. Very easy to clean with the basket system and motor and pump assembly very simple concept, may be a little tough to clean the ports need to use pet mountain's very flexible brush to clean the ports and water channel. Overall I highly recommend this canister over the fluval for function and quality and over ehiem for the price.

5-Stars especially for the price here at Pet Mountain! Bought this canister to supplement already great Bio Wheel filtration from Marineland (600W hood) and am as happy with this as any high priced Eheim filters I've owned before. The No-Bypass feature is worth having as some cheaper filters bypass when they are clean, never mind being dirty. Easy set up, totally silent operation and comes with all the media, what more could you want. The only minor thing I found was on the outlet diverter, it has two small adjustable wings that direct water and the pointed handles stick out and could injure a fish (like Oscars) so I simply clipped the handles off with nail trimmers and you can still easily adjust the wings by hand. Not enough to detract from its value, both intrinsic and financial. I'd buy it again in a heartbeat and it is as good as Eheim at about half the price. Much better then both Fluval and Rena...

This is probably the best filter canister available.

I got my C-360 about a week ago. First thing that I loved about it is its easy assembly and the fact that it is friendly to clean, i.e. easy to dismantle and put back together. I also love the PRIME button and the fact that it truly does what it says, the media doesn't slow down the flow, fully packed still pumps at 360 gph. There is enough space in the trays to place your favorite media (I put phosphate remover between the carbon and ceramic rings). Works great. Worth the money invested. Your fish will thank you.

Just got my Marineland C-360 canister. This filter does a great job, it went together easily, pumps a lot of water, and cleans well. The quality seems great, parts are sturdy, and it is very very quiet. It isn't silent, but makes no more noise than a small to medium powerhead. Overall I am very satisfied and am buying two more.
