Seachem Reef Complete

[BCOrchidGuy]

The bottle of reef Complete actually says on it, Ca levels above 400mg/L is NOT recommended. The bottle also recommends using Reef Carbonate or Reef builder in conjunction with the Reef Complete. "Reef Carbonate is a concentrated (4,000 mg/L) optimized blened of carbonate and bicarbonate salts designed to restore and maintain alkalinity in the reef aquarium.""Used as directed, Reef Carbonate will no deplete calcium, magnesium or strongtium which usually tent to precipitate with increasing alkalinity."

You may want to buy a SeaChem Ca test kit as it does measure all types of calcium, including calcium gluconate.
