The title of this thread is pretty self explanatory. I have a handful of SPS in my 10 gallon reef which include Montipora Undata, Pocillopora sp., and Seriatopora Hystrix (birds nest). I have pretty good polyp extension and general health, color is ok (could be better), and growth seems to be boom or bust. I have noticed in the last few months my corals have been lacking the white growth tips they used to have even though my care routine is pretty much the same. Alkalinity hovers right at 7.8-8 almost every time I test, Calcium is in the 550+ range, magnesium is 1500, and I just got an ICP test back saying everything is pretty much ideal other than slightly low potassium and slightly high lithium (which according to pretty much everyone does not matter and is a common result in most tanks). Tank health overall seems pretty good right now with everything finally rebounding after a pretty bad tank crash around 6 months ago. Any advice on what could be causing the lack of growth tips? Thank you so much for any input and help.
(Also, I know calcium and magnesium are high but according to most sources this isn't a big deal? I use IO reef crystals so it drives the mag pretty high. Could also use come guidance there.)
