Help Setting Up Sump

[Borderjumper]

I havent put a skimmer in mine yet. I needed an instant cycle, so I pretty much filled the sump with live rock. The intention was to remove the rock and put a skimmer in, after the tank was stable. Its running so well as is I think I may just keep it skimmerless.

If your using a skimmer, the chamber on the left may be too shallow? Ive got mine slightly overfilled to cover all the rock and its still shallow!

Whatever side you decide to use I dont think micro bubbles are an issue, the waterfall pretty much takes care of those.
