Filtration

[Rudles]

Is over filtration possible? Until recently I didn't like the idea of sponge filters however I've changed my mind about this after watching filtration videos and several reviews of the Aquarium Co-op sponge filters. I will be setting up a new 29 gallon acrylic show tank with dirted substrate within a few weeks. I plan on running two Aquarium Co-op medium sponge filters, one in each back corner along with a SeaChem Tidal 55 HOB and a Cobalt Aquatics EXT 26000 canister filter.

There is no such think as “over-filtration” which would be detrimental to the environment in your aquarium, but...

The scenario you describe is definitely overkill.

Detrimental? No.  But a waste of resources and money, yes.

Do yourself a favor and settle on one of those three types of filtration.  Make sure it’s sized appropriately for the application and ensure it’s properly cycled and maintained. Put the money saved towards more plant material.

I don't think you can have too much biofiltration, but you can definitely have too much circulation. I like to have two filters on each tank. A sponge and either a canister or a HOB. That's gives me insurance in case one or the other fails. I keep a spare air pump or two around also.

For a 29, 1HOB and 1 sponge should be more than enough biological filtration. You could get away with one of those, but I personally like to have a sponge in case I need to set up an emergency tank for any reason.

id maybe go 2 sponge filters (1 in each corner), or 1 sponge filter and the HOB. any more, and that water will be really moving hard, which most fish dont care for 24hrs a day.

The SeaChem Tidal 55 has controllable flow. I can slow it down and use it more as a surface skimmer.
