I purchased a house with a 21' AG pool just over 10K gallons. When I pulled the winter cover off my water was GREEN. I put in 4 gallons of liquid shock (12.5%) and fired up the filter. Over the course of the next 2 weeks my water went from Green, to cloudy, to hazy, to clear. I have done the following to get to this point......approx in this order!
4 gallons of liquid shock
1 container of $19 shock with stablizer from the pool store
2 bags of powder shock (58% of Cal Hypo) from the pool store, 1 week apart
3" Tri tabs in my skimmer
1/2 gallon of liquid shock on Sunday
13.5 pounds of Arm & Hammer baking soda (7 pounds on Wed night) - brought TA from 70 up to 125
2 lbs of Borax last night
Everything has stabilized in my pool except my PH level. My test results are as follows:
TC = 2
FC = 2 (these were at 3 and 1 until about a week and a half ago)
TA = 125
PH = 6.9 (tested this morning after 2 lbs of borax last night, was at 6.8, hard to tell exactly where it is, I swear I am color blind looking at the test results)
CYA = 20 (thus the reason I am using the tabs still, trying to up the stabilizer some)
TH = 233
I have been cleaning my cartridge 2-3 times per week. The weather is finally starting to improve in NE Ohio and I would like to be able to swim this weekend. My PH level is concerning to me as I don't want to damage my pool, or cause irritations with my swimmers. My water looks very clear, at least compared to what it was when I started.
Any thoughts on how I can increase my PH levels up to 7.5 without effecting my chemistry elsewhere? Any help is greatly appreciated! Water temp this morning was 68 if that helps.
