I only evaporate two gallons a day is not enough to keep the PH up above 8.3 for long . Like I said I can not increase evaporation any more the house already looks like i live in the everglades.
I can dose 100ml of B-ionic and get my ph up to 8.4 from 8.0.
If a slow doser was hook in to my system to dose the two part slowly , it may just be enough to keep the ph above 8.2 continually I don't know if that will work .
