ok made some more changes. and took some close ups of the sps as its changing colour rapidly. Did some re-fraging of my own coral too. (first time)
The only coral so far that has disliked the recent stone change over is the one on the far right. I gave it some firm advice "if i want your opinion, ill give it to you…NEXT!" Anyway we compromised and i lowered the flow rate through the stones. It may also have been that i changed the carbon at the same time or had too much carbon and this shocked it. Not sure what this sps is called. If anyone knows please say.
This is the 3rd stones change over i have done and it has been the most impact full regarding colour is sps starting to really come out.
