I made a DIY Kalk reactor and I run a Ca reactor and now hope to run them both, via Apex, to smooth out pH variation. For those of you that do this, how do you do it?
I was thinking it might be a good idea to switch between Kalkwasser and RO water for auto topoff, based on the tank pH (eg 8.1). Maybe I should just use the Kalk for topoff all the time?
My Ca reactor pumps run continuously, and my Apex controls the CO2 solenoid for pH = 6.5 only during daylight. (does it make any sense to turn on/off the recirc and effluent pumps too?)
Would I be better off just dosing kalk intermittently at night based on a pH threshold only?
I am not having any particular alk or Ca problems.
Thanks for your comments.
Special thanks to Randy for the plethora of reef chemistry info he's shared.
