low ph problem help needed

[jklkrkak]

can anyone help my ph is low and when the lights go off its even lower, i have a calcium reactor that runs 24/7 and a kalk stirrer that i have jsut brought, i have been doing in calcium hydroxide to try to raise the ph but it goes up then when the lights come on its around 8.2 then the lights go off anf it lowers to 7.89 is it being lowered due to the co2 being run 24/7?

How do i raise it and keep it up?
:rolleyes:

you can always add some marine buffer

[jklkrkak]

do not want to keep adding buffer every day would prefer to do it with kalk or calcuim reactor adjustments

hook up your kalk reactor to a PH probe...

the PH of kalk is around 12.0

i have an aquatronica that has a ph probe so i can use that to set it, do i want to turn the co2 off at any time as i know this strips ph?

[jag1979]

can you set the CO2 to turn off when the ph drops to X? Or turn off the Co2 at night and/or turn on the kalk at night. I drip my calc via a peristalic pump overnight to maintain a stable ph
