Empty tank as a sump - No compartments

[christyf5]

I don't have any compartments in mine and I've run that way for about 8 years now. I do have a filter sock tied to the overflow in the sump to reduce bubbles (no matter what mods I make I can't seem to reduce the bubbles) but thats about it. I have the usual suspects in there, heater, skimmer, couple phosban reactors for carbon etc and a zeovit reactor. Key is to have the length of the sump for bubble reduction (ie tank output at one end, return at the other end).
