I am about to go out of town for 3 weeks.. Im actually a little terrified, as Im leaving my pride and joy to a girl I know very well. I have written out a manuscript basically and walked her through all the procedures. I have been getting a little cyano here and there and changed my flow patterns a little hopefully alleviate my problems. Will adding extra "cured" LR to my sump maybe help alleviate any nuisance algae while I am away? I have already turned back my lighting to actinics for 8hrs and Daylights to 6, so this should help.
