I have a 6wk old 75 gal FOWLR for now. 75 lbs lr, 20 lbs ls, skimmer, and canister filter full of lr. all chems look good. Wife and daughters impatient so have fish already and they are doing great. <span style="color: Red;">NOW the question is: I do not see many, sometimes none, pods on glass. How do I know if they are there or is this not a problem to worry about?</span> I am planning to set up a sump/fuge in the near future.
