Had my water tested at an LFS
who I trust because (too late) I found out the API tests were not the best. I mostly wanted to see calcium. My test from the same sampe read 440 while the lfs
read 400. Not great but not bad. She did however say my mag. was a bit low (1250) and mag is required by corals to enable them to process the calcium.
1. What level is preferred for Mag.
2. Is her statement about it helping the corals process the calcium accurate?
3. Other than dosing is there any good way to raise mag?
4. If dosing is required, what would you suggest?
As always, thanks so much for all the help.
