Calcium PPM keeps rising from no apparent reason

Hi Reefers,

I have been battling with my reef chemistry for a couple of months or so now, and while most of it is under control i still struggling controlling my Calcium PPM. I have a Red Sea 170 L system which is fairly well stocked and have a decent consumption of Alkalinity with below following parameters:

PH: 8.2
Temp: 25.8 deg. C
Salinity: 1.025 SG
Nitrite: 0
Nitrate: 10 ppm
Ammonia: 0
Phosphate: 0.18 ppm
Alkalinity: 8.8 dKH (… stable!)
Calcium: 540 ppm (… and rising!)
Magnesium: 1350 ppm

I am dosing the following every day to maintain my levels as per above:_

Red Sea Foundation (A) - NILL (Calcium)
Red Sea Foundation (B) - 9 ml (Alkalinity)
Red Sea Foundation (C) - 4 ml (Magnesium)
Red Sea Foundation (AB+) - 5 ml (Coral nutrition)

Thanks 🙏

It would seem that you are simply dosing more calcium than your tank is using. Dose only as much daily as your tank is using to keep the levels constant.
 
I would have to agree. I would stop dosing calcium until your numbers start to fall
