One of the mysteries of this hobby is how there are many roads that lead to the same end. It depends on who is driving the vehicle. My 135 is loaded up with about 50 coral
frags. Haven't counted lately and I've added some recently plus have three more coming Friday. I have stayed away from the Calcium reactors,
Kalk and lime water additives in favor of Ocean's Blend 2 part plus their Magnesium additive. If you are not adding Magnesium, get a test kit and test it. Natural sea water is 1250
ppm. When the importance of Magnesium was first explained to me I tested and my Mag reading was 850
ppm. No mater how hard I tried to maintain Calcium at 450 -500
ppm it would drop to 300 - 350
ppm in 24 hours or less. The funny part was my corals weren't growing for using that much Calcium. Since I've been dosing Mag I'm able to maintain 450 to 500
ppm Calcium, my
Ph is more stable and so is my
Alk.
I'd highly recommend checking your Mag. I keep my Mag around 1400 and things are looking good.
