polarbear Posted May 14, 2012 Share Posted May 14, 2012 So this morning I was going to do a water change because I have been having a hair algae problem. I talked to the guys at elegant reefs last week and had my water tested. My PO4 have gone down from .1 to .062. They advised me that the hair algae should start dying off and could be sucked out within another week or two. Well a couple of days ago I got a tooth brush and scrubbed a piece of the rock and the algae came right off. I was going to do the water change today and get in there to scrub the rocks but I was thinking that maybe the 3 days of darnkness would help to losen it up some more so it won't be to hard to get off. What do you guys think? Will it hurt to do it since I'm going to do a 20 gallon water change when the 3 days are done anyways? Also usually when the lights go out the fish hide so how do I feed them during this time? Do I just put the food in the tank with the lights off and hope they eat it?

Robb in Austin Posted May 14, 2012 Share Posted May 14, 2012 The 3 days will help loosen it up, so yes do that and then the WC. My fish got used to it when I did it, I just fed them when I saw them out. They learn pretty quickly. Quote Link to comment Share on other sites More sharing options...

polarbear Posted May 14, 2012 Author Share Posted May 14, 2012 Should I turn my refugium light on at night during these 3 days? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted May 14, 2012 Share Posted May 14, 2012 If you don't have any GHA down there, yes. It will help keep the pH up. Quote Link to comment Share on other sites More sharing options...
polarbear Posted May 14, 2012 Author Share Posted May 14, 2012 Thats what I had though regarding the PH. As for hair algae in there I did see a little on top of the cheato but Im going to be cutting the cheato back since its been growing really good. I need to make room for it to grow out again.
