If the calcium is that high without additions of a stand alone Ca
product then I would have the Mg
tested. Low Mg
will cause Ca
to climb independantly without additions until it gets quite high. I would also look at what a new batch of SW
tests at to see if that's the cause. 500 ppm Ca
will cause you problems eventually. It causes scleractinians to deposit CaCO3
much faster but in doing so the skelatal structure is very brittle and reedy. If it gets much higher, you could also experience polyp bail out with your LPS
Edit: I know my goal is 430-450... I have only a small hammer coral, flowerpot, and green mushroom atm.
Actually I would suggest your goal be 400-420 ppm
. There's no reason to go beyond NSW
levels. It serves no healthy purpose. Balance the alk
and you'll be suprised how healthy your corals and mobile inverts will be.
