total system volume is 50 gallons. i keep alk at 8.3 with kalkwasser and the temp is between (77-77.5) i test ph through apex EL probe.
I have a tunze 9004 dc skimmer, attached to a brs scrubber using icecap media. i dose 400 ml kalkwasser (1.5 tsp per gallon) or .2-.3 dkh worth daily on continuous mode with versa pump. i have great surface agitation with return pump nozzles pointed towards the water surface.
the past two months, in addition to what i mentioned above, during the day i have been opening the windows in my room (the tank is in my room) and turning the ac off. at night i close the window and turn on the ac. this has kept my ph between 8.05-8.2. I figured the temperature outside was in the 60s-70s so there was no reason not to open the window and boost ph even more.
recently its gotten hotter so i cant keep the window open and my ph has been between 7.85-8.05. this has been causing issues with alk uptake and causing me to adjust the kalkwasser dosing making it even harder to raise ph.
is this skimmer too small to benefit ph with a co2 scrubber? is 400ml kalkwasser not enough in a 50 gallon system to raise ph? is surface agitation raising ph or does it depend?
i have raised the skimmer a bit so i could increase the air intake, havent seen a difference. i increased surface agitation by increasing flow on return pump, haven't seen a difference. kalkwasser hasnt created a noticeable difference on ph since i started dosing months ago.
I'm going to keep the windows closed from now on just to keep the system stable and try to go from there.
