Calcium is always low

[Markerum]

My calcium is always low at 370. Right now I don't do anything just regular water changes with reef sea coral pro salt. All my other parameters are at 0, Alk is low as well: 7 and PH 7.9
I run 2* 150W HQI and 2 * 65 power compact 10,000k and 2* 65 PC actanics.
I have added a bunch of frags and I now need to increase my knowledge in the calcium area. How and what ways are there for safly adding calcium to raise levels. What products are good. My tank is a 60 gallon and 29 refugium.
Any good links to articles will help.

Im dosing ESV B-ionic 2 parts calcium/alkalinity buffer system. Great product and easy to use. Highly recomended.

I would think this salt should mix up at a higher Ca level. Have you tested it before adding it to your tank? If it is higher before going into your tank check your Mg, low Mg is often related to low Ca. I drip kalk but I don't use a reef salt so it mixes up at 360.

Many tanks require daily alkalinity and calcium supplementation. A 2-part like B-Ionic is a fine way to get started, in my opinion.
