Urgent Omg stn.... Its starting all over again!

Test out your new water before you start doing too many water changes; the problem may lie there.

 

I will do that again, for now I removed gfo offline replaces carbon and 5g wc

 

I always had issues with SPS when I ran carbon. As well not all carbon is created equal.

 

My tank has been going downhill the past week, Everything seems to be in check, slowly having STN in some areas one after another. only thing i can pinpoint is to the GFO as i just replaced it. Heres a FTS as of yesterday..

 

the tanks looks clean, is it just the sps that you are concerned about?

 

Well, Things are getting better, stn has stopped and pigment has grown back to the dead spots. thats a good thing.
