Tom Aquatics Floss/Carbon Filter Media for Rapids Canister Filter

The Rapids Mini Canister is a compact and efficient canister filter. Providing 3-stage filtration, mechanical, chemical and biological, aerating and filtering the water every hour. The Rapids Canister Filter has a self priming, top mounted sealed motor with a flow rate of 80gph. For aquariums up to 20 gallons, the canister is lightweight enough to hang directly on the back of the aquarium.Mechanical filtration is provided by the replaceable floss roll impregnated with highly activated carbon.

Comments: I am using this with an aqua lifter to dose kalk. It does what it says, it filters. I do not see any kalk sediment enter my tank, and I would presume that it extends the life of the aqua lifter when used with kalk. The sponge inside can be easily removed and feels durable enough to wash. Easy to use. Happy with it so far.

Comments: The instructions for these carbon pads are not to use them continually, but I was told by some aquarium people to use them regularly to give the water a sparkling clear "polish".Eheim is a good product.
