    This does explain some things for me. When I clean the filters in my HOB filter, I ususally have cloudy water in the next week. I have a 75 gal fw aquarium. One HOB filter and undergravel with a power head. I'm thinking of removing the undergravel and going with a canister filter along with my exsiting hob.

    Thanks for the good post!

    I fully agree with your post. I have always believed this, but didn't even consider many of the points you make. A very interesting read!

    Agreed! I had 2 12" goldfish in a 90 gal that required 75% water changes weekly (sometimes twice weekly) to keep nitrates manageable. I always ran 2 filters and alternated cleaning them. In 6 years not once did I have any form of "mini cycle".

    I have two filters running on my 55g. An Aqueon 55/75 and an Aqua Clear 70, both with bio media in them. I recently bought a new 29g tank with an Aqueon filter and took one of the filter pads from my55/75 and popped it in the new one. That combined with using some gravel from my 55g really accelerated the cycling process. All levels were perfect within days. Will be adding a second filter to the 29g very soon.

    Just another benefit to multiple filters.

    I would add that after one has a standard bio-filter of some type, and wants more filtration then an algae filter is the next best 'extra' filtration unit.

    These not only remove nitrates but also phosphates (something no other standard bio-filters remove) and better still, some types of organics (but not all; water changes are still required.)

    Since the newer up-flow units are relatively cheap and very small, even a ten gallon tank can hold one with little impact on the tank's internal "look". These units cycle up fast and can also consume nitrites and ammonia (for this reason, adding these units to a start up tank might be a bad idea; the standard bio-filter might not cycle.)

    As for plants, these units will compete with these so it would be important to check nitrate levels and phosphate levels in a heavy planted tank to be sure they are high enough.

    The Wiki has a good post on these critters (

    Knowledge is fun(damental)

    A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.
