Always have Muriatic Acid on hand?.. pH jumped to 7.8+ after rains (previously at 7.4)

[Ticojpunk]

Lots of little storms and rain in NY lately. My pH has been a pretty constant 7.4, but checking today, it seems to be up at 7.8 or possibly a bit higher (hate reading color gauges when they don't match one of the given values/shades exactly).

Other current numbers are...
CYA 50
FC 8
CC 0
TA 120 (this has remained consistent, my tap/hose/city water is 120).

Should I be adding any muriatic acid at this point, or leave it alone? The other question is, is it a good idea to have a jug of muriatic acid on hand in the event I do end up needing it? And what brand to get. I'd likely get it from Home Depot, because I don't think I've seen muriatic acid at Ocean State Job lot.

I DO have on hand...
pH Minus (93.3% sodium bisulfate, 6.7% sodium sulfate),
... but I'm pretty sure you guys tend to recommend muriatic acid.

Any standard muriatic is fine. You can let it rise to 8.0 before you lower it. Avoid pH Minus. Throw it out.

Is this "green" stuff ok, or avoid?

It's ok, we can find you better. What city are you in?

Anything low/no fumes is watered down. They list 10% to 30% on the MSDS but would be bragging if it was 30%. Instead, they hide the strength. You be the judge there. Lol.

It's fine but you need up to 3X as much.

Ace hardware has full strength for $10 to $15 depending on location. HD/Lowes has the weak stuff for a similar price range.

Thank you! I know that place, didn't realize it was affiliated with Ace. I normally just see plastic patio chairs piled up outside the place, just always associated them with plastic chairs. lol.

If I do reach pH of 8, how much should I aim for lowering the first go-around? -0.3 a safe way to go?

Lower in .4 increments. Test 30 minutes later.

Directly pouring in front of return jet ok with vinyl liner AGP?

 

[PoolStored]

Yes, very slowly...like a gallon in 2 minutes. Brush a bunch to mix and not let it sit on the liner.

They have this… TFP approved?
