meeiu Posted September 26, 2012 Report Share Posted September 26, 2012 (edited) So my 2 month old 10 gallon soft coral tank's live rock have begun bleaching a few days ago. The rocks are slowly turning white and the coraline algae is disappearing. Anyone else every experience live rock bleaching and if so, what is that cause? Thanks Edited September 26, 2012 by meeiu Quote Link to comment Share on other sites More sharing options...
Vitaminz Posted September 26, 2012 Report Share Posted September 26, 2012 What is your lighting specs? What is your lighting schedule? Also do you dose any additional chemicals? Do you use tap water or RO? Have you tested your water parameters, and if so what are they? Jeff Quote Link to comment Share on other sites More sharing options...
meeiu Posted September 27, 2012 Author Report Share Posted September 27, 2012 I use a single tube of 24'' T5HO and the light is suspended about 4'' above my tank. The lights go on for a 7 hour photo period. I do not dose and I use Reef Crystals with RODI water. When the rocks first came, there was almost zero Coralline Algae. Then as time progressed, more and more started to develop and grow. It was only until recently where the rocks began to turn white and bleach. So I think what I did was decrease some of the photo period... Quote Link to comment Share on other sites More sharing options...
