Well the cover came off today, the water was crystal clear and I started the 2023 pool chemical routine. I had a few firsts since owning our first pool 20 + years ago. My first first, CYA was higher than I measured last year even though I drained about a foot of water at closing; they must have been having a party in my pool and reproduced!

Now I have a 14 lb bucket plus a little that I didn't use last year so basically I wasted my money this year for CYA. I do plan on retiring next year so I'll look at it as a future pool investment. My second first is I got a whiff of muriatic acid, smelled a little like vinegar (I think, didn't whiff too long!) because I put too much washing soda to raise my pH and TA a bit so I had to knock it down. I truly get paranoid about certain things so now that it happened I'll be a little bit more paranoid!! My third first was adding salt to the pool. The water is 60 F and I dumped in the first bag thinking "OK, how long will this take now" and I was pleasantly surprised in that I think it took maybe 15 minutes. I added a second bag and the same thing so all's good.
Readings from the testing:
CYA: 90 or 100, lets shoot high so 100. It measured 80 last year, not sure what happened. I'll let it burn off or when I backwash/refill it'll lower. A little higher than I want but at this point I think I'll leave it since I have a SWG and it's recommended to be around 70-80.
FC: 13 after putting a gallon of liquid chlorine
CC: was using the 0.5 scale and it was slightly pink and 1 drop turned it clear so anywhere from 0.2 to 0.5 (?) I don't know how pink it should be for a "true" reading.
pH: 7.6 BUT I now forget if that was before or after adding the chlorine so it could be invalid.
TA: 70 before adding muriatic acid and I didn't test it after, I will assume that if it knocked down the pH it should have done something to TA. Measuring tomorrow.
CH: 50
Water Temp: 60 .... Brrrr
So now here's a question - with a SWG do I have to worry about the CSI (-1.38) because of the metals in it or is that only for "stone" IG pools. I don't want to have the metal be eaten away by a corrosive condition. Logic tells me no problem since pH is above 7.0 but just want to check.
Here's the pool after opening, if you look closely you can see the swirls on the liner. Crystal clear!
