Calcium PPM keeps rising from no apparent reason

[CasperOe]

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
