Hello, I perform regular maintenance on a 3000 gallon frag system with many 100 gallon troughs and one 800 gallon trough with tangs. I dose a kalkwasser-vinegar solution; and use 6 large filter socks as our only source of filtration. As of late the alkalinity has been slowly rising to now about 11.2 from about 8.2 over the last 2-3 weeks. No methods of maintenance have changed and all other parameters remain the same except a slow build-up of nitrates which water changes usually take care of:
Calc: 460-480
Mag: 1350
Phosphate: <0.03
Salinity: 35
Temp: 78-80
PH: 8-8.2
Nitrates: Usually <5 have risen to 25 on occasion.
..I hope to install a large protein skimmer when the funds are available but that doesn't seem to be the near future.:headwally:
Anyway if anyone can think of any reason the alkalinity would be rising any advice is welcome, also I have stopped dosing kalk in the last few days because calc and alk are so high. To no avail.
