I am thinking about switching from Instant Ocean Reef Crystals. A freshly mixed Reef Crystal at 1.026 sg tested at 8.2 pH / 9 KH / 370 ppm calcium / 1280 ppm magnesium with API Reef master kit and Red Sea magnesium tester (the ones using liquids and bottles). I'm not sure if it is my test kit or the Reef Crystals I got suck, but I'm not too happy with how it is lower than advertised.
Would this be good enough for LPS corals, coralline algae, and clean-up-crew inverts with hard shells? Should I stay or change? Which do you recommend?
