Thank you so much! I keep the parameters steady as I can. Calcium reactor helped a lot. Took me a wile to dial to what I wanted to. Doing AWC helps too. Corals were better when I had high nitrates. Now with low nitrates sps’s are not so colorful as before.Absolutely beautiful. I love what you have done with the new Aquascape. It is now one of the best tanks I have ever seen. I know you were struggling with SPS before what do you attribute your success with them now to? Thanks and take care
