I have a few questions about what & how to adjust... Here are my numbers:
22,000 Gallon inground plaster w/ sand filter.
My pH has been running a little low (7.2-7.3) all summer and I haven't really been too worried about it, but it's not been this low before and I want to adjust it.
What do I adjust first: pH or TA? I do not have a good way to aerate (return is through the in-floor cleaning system) and I'm thinking that since it's been running on the lower end of the range that I need to add something to raise it now. Should I raise the pH with Baking Soda, since that will raise my TA also? Or should I use the Borax to raise pH and then re-test and adjust TA? Also, do the borax & baking soda have to be diluted in water prior to adding or can I just dump in the powder?
I'm using trichlor pucks as DH had no patience with bottles of bleach and his buddy told him to go buy the in-line puck feeder before I had him talked in to the Liquidator. Does the trichlor affect pH? We are in monsoon season now and getting a ton of dilution, so I'm just trying to understand if the pH is creeping down due to dilution or if there is another factor that I need to keep my eye on.
Thanks so much for any help!!!
