So I recently tested my.friends calcium and it was over 600 (using a Hanna tester), and I checked my tank just to see if It was accurate cause that seemed really high to me and mine tested at 510. I mixed 5 gallons of the salt he was using(we use the same HW reefer) and it was 520. After doing a 5 gallon water change I'm now testing mine at 540. I'm not sure if maybe my tester is accurate and thinking about getting an Elos test kit to verify. Should I be concerned if my calcium is at 540? I bumped up my PH and my KH and my MAG.
my KH 8.28 my KH 8.0 and MAG 1320 before I bumped them all up. Figured if I increased the ph, kh, and mag it will drive the calcium down. I usually have calcium n the 450 range but been sucking out some of my sand bed a little at a time so I thought that might have somethING to do with the calcium being high, but that doesn't explain why the new water I tested was at 520. Maybe a bad test vile?
