question about reverse flow undergravel filter..

[kido]

guys, how exactly do you setup a reverse flow undergravel filter? where and what position would you put the powerhead at? and can you do reverseflow using areator alone?

i've heard they are pretty effective and i'm goin to test its effectiveness in a 35gal tank so any help would be appreciated especially those with illustrations for me to easily understand

I have heard of this and it would reduce the problem of detritus accumulating on the substrate, I have never done it. The one tank I saw rigged that way had a small power head on each uplift tube but backwards so it pulled water through a coarse screen and forced it down the tubes so that the cleaned water came up through the gravel. The guy who had the tank said he had to downsize the power heads or it made the gravel dance.I like ugfs but only as a supplement to other filters. I runthem from different powerstrips on a seperate electric circuit so if a breaker trips at least one type of filter is still running.

I think reverse flow UGFs work best with canister filters as it has more pressure and it filters the water before you pump it under the gravel to prevent dirt from accumulating under the sand bed. Try this article if you want to use an air powered one- http://www.thekrib.com/Filters/rugf-dixon.html
