A Theory About Rising pH in SWG Pools

[dawndenise]

Still looking for data? Pool is not quite 3 months old and pH is quite comfortable at 7.5. I add muriatic acid only when the color gets a slight pinkish tinge to it, rather than waiting for it to go up to the next #. Am only in my 3rd gallon of MA since pool filling. My target is always 7.5, since that's where my pool has "said" it's comfortable. Who am I to argue?

SWG online for about 2-3 weeks now. Add acid about every 10 days thus far; no appreciable change since the SWG became operational. Waterfall on 12 hours per day.

TA=80, CH=220, CYA=45, FC=5-9 range, salt=3400; generator set at 60% for 12 hours; water temps 84-89.

Fill water is very high ph (over 8), low in calcium hardness (50-ish), about 70 in alkalinity.

I just can't bring myself to drop my FC into the 1-3 range, increasing my CYA into the 60-80 range, as per SWG's recommendations.
