I just added a refugium on the back of my 65 gallon tank. The light stays on all the time(that is what I was told to do)I have some algea growing on the sand and on the acrylic. I bought some macro algea but it died(was in the wrong spot and I didn't see it until it was too late) Do I add a cleanup crew to it, leave it alone??? I have macroalgea ordered for it. Thanks for any help.
