So if i am using a Skimmer specifically for gas exchange and increase my ph. would it be best to remove the skimmer all together if running kalk? But again my kalk dose is only .4dkh per day.Adding kalkwasser creates a CO2 level in the water that is lower than was there before you added it, which raises pH. A skimmer allows the tank to pull in CO2 from the air faster:
Ca(OH)2 --> Ca+ + 2OH-
OH- + CO2 --> HCO3-
