SPS Bleaching

[purpletang123]

I have a small unknown sps colony that's doing fine until today while feeding my fish, I saw a small part on the back of the coral is bleaching.What should I do, what cause this? My parameters are good. My supspicion is I added rowa and chemipure elite at the same time on the 2nd of March, is this the cause?

rowa can affect your alk, might have stripped to many nutrients out of tank too fast.

so, should I turn off the reactor for a few days? When can I turn it back on?

I run a full blown sps tank and don't run Rowan or carbon in a reactor ever. I think it's to harsh on the corals. The products work to good /fast in a reactor. I recommend running it passive if u want to run either just in a mess bag in the sump. Jmo. U say your parameters are good but that dosnt mean anything. What r the numbers. Also what's the lighting and how high up in the tank?

Bleaching is normally to much light, alk swings, temp swings, I have also seen bleaching in low ph but lots of arguments on the ph part.
