I am fairly new to the hobby. I have a 60g that is 2 months old with 40 lbs. of live rock, external wet/dry with skimmer and am just beginning stocking. I presently have two clowns and various inverts. However, I have had a problem with hair algae for about one month. It is not on the live rock at all, the snails and crabs do a tremendous job cleaning it, but it is all over the sand. I remove it and about a week or so later it reappears. I do not know how to combat it. I used to top off with tap, but about two weeks ago switched to RO
water. It has not seemed to help much. My lights are only on about 10 hrs/day, I do not overfeed, and my parameters are all good. Do I just wait it out, keep cleaning, and hope it eventually goes away? Please help.
