If your running probiotics it is imperative that you keep your alk below 9dkh. I would recommend a quality kit such as Lamotte. At 9dkh many acro tips will burn. Get your alk around 8 and stable and calcium/magnesium will fall right into line. Then just keep it stable. Also if you use the carbon/bacteria to keep nutrients low but not at zero you run less risk of tip burn. I also used probiotics to allow myself to feed more as opposed to driving to ultra low nutrients. That will keep your corals growing, your colors rich, and your fish fat.

p.s. that chalice I bought at your place is surviving nicely. Nice turquoise color with pink eyes. Had some good comments regarding it.
