Ok guys I'm definitely not a regular poster and sometimes I say a lot in a little time and then not a little for a lot of while but I need help. I have been battling snot for a while now in my 90 gal reef. I thought I got rid of it twice now and it has returned with a passion now. I have vacuumed blown and everything I can think. I may be missing something but my water seems to be right. I'm going to check again tonight and I will post results just so all can see. If there is anything I can try safely please let me know. The only thing that seemed to work the last two times was 3 days in the dark and then slowly increase lighting over the next week. I'm hoping to not have to do that again. Thanks in advanced for ANY suggestions!
