eshook--I did that on my 55g, with an Excalibur skimmer. Doing this along with adding a needle valve to the air line and a MJ 1200 pump I end up with a cup full dark skimmate a day. That is from a very lightly stocked tank. I didn't even have to put a hole in the bucket. Just went to the cooking section of wallmart with a tape measure to get a Tupperware tub the correct height and diameter.
This is where RC started saving me lots of money. I was told by the LFS that the Excalibur was the best skimmer around for $125.
I was able to recover from at least one of my early mistakes. That is the reason I became a premium member, I wanted to thank them for saving me a lot of money.
I guess that's enough of my late night rambling.
