The easiest way is a balanced calcium chloride, sodium bicarbonate/carbonate additive. Work slowly to find a balance ideally between 7 and 10 dkh and 400 to 440ppm calcium.
Also having truly no phosphates can be a problem that will cause the tips to go white and dieback. Reduce GFO if you are using it.

Ok good to know. I didn't think I had enough in the tank to need supplements.
I have no GFO running. I do have carbon though. Also have a skimmer. Should I shut that off for awhile?
