I understand there is sometimes a bit of a balance to keep SPS and LPS together, parameter wise

The food supplements weren't added right off, but a couple weeks after the fish food was doubled. The biggest noticable change colorwise was after upping the fish food - to the good. This is why the coral foods were started
I have some come-back of HA, but nothing unmanageable

I've upped my dosing timers to increase my Alk and Ca a bit as raising the KH was suggested by another just a day or two ago. I'm going to try and target up to 8dkh and see what the Ca does. Hopefully it will be easy enough to get it stable in the 420ish range
