Corals bleaching

[happaman]

I would remove the carbon and move the corals to a little less light if you can, rather than change the light intensity and / or schedule.

Good suggestion. +1 the carbon/light being the issue. I had this happen before. Changed out carbon (after letting it go for months) and bleached all my sps which were prolly already stressed from poor maintenance.

It could be the carbon... just didn't think you would notice its affects 3 months later. It will polish your water and make it more clear... so your corals are getting more light than they are used to. Did you change the carbon just recently?

Good job Cody! I also believe is the carbon for the same reason. Turn ur lights down 2 hours and target feed the plate. It will recover. After a month evaulate the plate and increase photoperoid to what u have now. Try to use carbon more frequently and u should be good. Also my rule of thumb is one cup per 100 gal for carbon hth
