undergravel filter.

[7620le]

so as the title state. i would like to know more about undergravel filter.
I have a 30G fish tank with about 7 tiger barbs and a sailfin pleco.
so i was wondering how does a undergravel filter work and is it possible to make your own design for it. What are the steps for this?
any comment or help would be thankful =)
:thm:

PPPPfffffft!!!!!!

30 gal is too small a tank for a sailfin pleco. You will need a tank with at least a 48" footprint.

A UGF can be driven by air from the air pump or by a power head. You will get a higher flow thru the substrate with the power head, which is desirable.

A more preferred way to run these filters is in the reverse mode, RUGF, with a power head pushing water back down the lift tube, under the plates and up through the substrate.

This helps lift the debris out of the substrate and keeps it in the water column.

I agree with Rb, RUGF's are much more efficient, especially when complemented with another filter such as a HOB or cannister.

Yeah, RUGF would be far superior to a regular UGF.
