Starting from scratch (new water)

[jilted]

Just checking in. Water has been pretty good.

FC has been easy to manage so far.
Having trouble getting pH to level off I guess the SWCG is keeping it increasing. Also the alkalinity never drops when adjusting pH.

Test today:
FC: 5.5 ppm
CYA: ~50 ppm
pH: close to 8
Alkalinity: 140 ppm

I've dosed muriatic acid a few times according to the book in the taylor test kit. 2 drops bring the test in line. The ph does come down after this but rises again in a couple days. The alkalinity stays 140.

I've been running my pump 18 hours a day which should be enough to circulate the whole pool twice. The SWCG was running at 100% but I have reduced it to 80% to see if thats enough to keep the FC stable.

Any input on my pH/alkalinity situation?

Thanks!

I'd target 7.0 - 7.2 for pH and try to keep it there until the TA is where you want it.
