Hey, my calcium, magnesium, and alk are all a little on the low side. All corals look great, A few lps and zoas. I was hoping the 20 percent weekly water changes would keep levels up but I guess not. 29 gallon tank no skimmer. Have a dosing pump on the way and was wondering what are you guys using? Brs 2 part the way to go? Thanks!
