I had "nearly perfect" parameters before my last water change. Thanks Intant Ocean Reef Crystals! My Alk spoked to 10.2. At any rate, the millepora looked the same before and after. It is one of my best growers, just not so pretty. Thanks for the input.I do agree your parameters are a little skewed calcium magnesium and salinity are all a bit high compared to alkalinity. Check out the reef chemistry calculator and put your info in to see "balanced" numbers you can and should shoot for.
For example, if you want to keep alkalinity at about 8.0, then you would want calcium of 420 and magnesium of about 1325. But you probably want to correct salinity and re-test before doing anything.
At the reef chemistry calculator you may hold for anyone of the values and calculate the rest.
