I have a reef for about 7 months and the thing that gives me more headaches is mantaining calcium and hardeness in high values.
I use an osmolator for top-off water with Kalkwasser that adds more or less 2 litres of water into the aquarium.
With this method I only get 380 mg
/l of calcium and about 125 mg
/l or 7 dkh
of carbonate hardness.
Too low won't you agree ???
I then started adding addictives like dkh
pro buffer or part A+ part B both from kent marine till I reached 11 dkh
or 200 mg
/l hardness.Then used kalkwasser to mantain and a couple days later both values started falling again.
Why ??? am I suposed to substitute kalkwasser with addictives ??
Please help me find a solution
