The H.O.T. Magnum is a compact, silent, and efficient canister filter. It provides mechanical and chemical filtration for aquariums up to 55 gallons. The Magnum has a self priming, bottom mounted sealed motor with a flow rate of 250gph. The H.O.T.(Hang On Tank) Magnum filter is lightweight enough to safely hang directly on the back of any aquarium, and yet performs heavy duty, canister filtration. The two stage filter can quickly and easily convert from a continuous duty filter to a quick-clean micron water polisher.
Mechanical filtration is provided by the replaceable Rite-Sized Foam Sleeve. The foam sleeve is a dense, high porosity prefilter to trap dirt and debris. Chemical filtration is provided by a Carbon/Media Container packed with carbon to remove dissolved organic impurities.
The H.O.T. Magnum easily converts from everyday 2-stage filtration system, into a fine particle quick-clean polishing filter, by simply switching the carbon media container with the pleated Micron Cartridge. Ideal for quick-clean duty, the reusable Micron Cartridge has 320 square inches of surface area. It efficiently removes microscopic particles, eliminating the need for diatomagic powder. The H.O.T Magnum installs in minutes which makes it ideal for multiple aquarium water polishing. The snap lock and leak-proof connectors eliminate the need for hoses or tubing.
Includes Micron Cartridge, Carbon Media Container, Filter Sleeve, Carbon.
I have used these filters since the 90s. I've used 2 on a 90 Gal tank: 1 with carbon and the other with mini ceramic balls for biofiltration with outstanding results.
I've used foam filters as a sleeve on the intake to reduce the water flow for slow swimming fishes and babies with very good results.
The outlet can be turned to face the front of a tank to reduce the water flow as well.
The only problem I ever had was when I tried to use the filter with the outlet raised to create a fountain effect: This caused the filter to leak at the pipe connection in drips, so be sure to use it in the position recommended by the company, or not turned up out of the water too high.
I've never had any manufacturing problems.
I love the H.O.T. filter 1/29/2014

I have owned these on multiple occasions and have one currently. I will always own one of these as long as they continue to make them. They are excellent polishing filters and great for seeding new tanks because they are easy to move. I keep the media canister loaded and in my sump to maintain bacteria and move to new tanks for startup. I highly recommend this to all aquarist new and old.

I had a magnum 350 for several years. As soon as I opened this one the impeller magnet was split so I had to order a part before I could even use it. Very finicky to keep the prime going.
works great 11/15/2013

So far so good. i put it together as per instructions and its quiet and working fine!
adjust the water return and you can have air bubbles or not.
great multi-use filter. 5/3/2013
I have used these for years, with bio-wheels for complete filtration, and without as a multi-tank polisher, or hosp tank filter. Currently without, am planning on getting one to occasionally polish the water in my 75 gallon planted (using an emporer power filter for main filtration).

A big let down the motor burned up after two hours I will stick to eheim canister filters from now on I know how they work I have four of them and they are great
I've "had it" for a year... 10/26/2012
Very messy and finicky to change. If water level in filter not up to very top, if exhaust port not below water level or for other, unknown reasons, filter will not function after cleaning. Do NOT use if aquarium is over carpeting, unless you like wet carpeting.
great product 9/19/2012
I have two of these in use for 16 years yes u read right 16 years on a 75 gallon they work great. keep clean and they earn there keep.

filters work good, no problems so far, had them for almost four years. if you keep them clean, cleaning means, clean every part, in the filter. i clean mine every eight days,and the suction is good. good water means healthy fish

I absolutely love this filter. It is so simple to assemble and install and works as promised. I like the fact that there is a power button to shut off during feeding time or when you want to swap out the media for water polishing. I only wish there was a way to reduce the output of the water returning to the tank. Some of my fish have a hard time swimming against the current when caught in the path.
