Marineland & Magnum Polishing Canister Filter filters a lot of water as it says. It's very quiet and the filter sleeves aren't very expensive. I have it on a 46-gallon bow front aquarium. It makes a nice wake that a few of my fish like to play in, which is really funny to watch. My only complaint so far is that I have to change the filter sleeves often, perhaps because my fish don't finish the food fast enough so it doesn't get into the filter.

Works like a charm! I had a problem tank that was always a bit cloudy. I charged the MARINELAND MAGNUM POLISHING FILTER with some Diatometric earth and put the filter in the 30 gallon spawning tank in the evening and by morning the tank was crystal clear. I also used it after rearranging plants in my 80 gallon barb tank, It was amazing, I set it up around 15:00 and by 19:00 the tank was crystal clear. I LOVE IT! A very long time ago I had a Diatom filter that I got at a sale and it worked pretty good but this filter is 100 times better and easier to use than that old clunker. I will be looking at Marineland products a lot closer now.

Used Marineland 250 for many years good filter but time consuming to clean to many parts. This internal canister filter took me 5 minutes to set up so convenient and it filters 296 gallons per hour 46 more than the 250 at half the size. Exceptional and will recommend to others THANKYOU for making it easier.

Great submersible filter. I use this in a 25 gallon but it would work in an aquarium much bigger. Crystal clear water..Media/charcoal container inside is awesome.
