So I have a 55 gallon DT with a 20 gallon long refugium. Corals consist of all frags, 6 zoas, 1 hammer, 1 frogspawn, a small acropora, candy coral and a ricordia. Excuse the spelling. I probably have about 60 pounds of live rock. One clown fish and a mess of inverts. I recently added 2 led
units to replace my T5s. Now I ve noticed the corals going ape but my coralline is getting bleached looking. So I brought in my water to LFS
to get checked out and the results were calcium was low. It was at 340. Now my question is. Are the corals sucking up all the calcium and depriving the coralline. I have never dosed, just been doing LFS rodi
water changes weekly at about 8 gallons a week or so. I bought a calcium supplement to dose with, but I'm nervous I've never dosed any trace elements before. I guess I've never had to.
