Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I have this same question. I'm down grading my mothers 125 gallon reef tank to a 40 gallon nano since she was diagnosed with cancer. I’m going to keep the 30 gallon sump and the MRC 2R skimmer.
I never felt you could over skim/ filter a tank, figures I’d see what others have to say.
