We had some rain in baltimore the other night along w a bit of sleet and snow and now my PH is reading much lower. It's showing almost perfect now 7.5ish. Is that likely or should I keep retesting?

Re: What do I balance first - pool start up
pH should be tested every day especially when cleaning up or when it varies.
How's the spring clean going? Did you get the debris out? Have you tried the overnight chlorine test?
Re: What do I balance first - pool start up
Finally cleaned all the junk out of the pool. It got way cold here over the week, had to take a break. I kept dumping bleach in the pool though to keep the FC up. Poured in a gallon of acid yesterday so will test again today. I will search here for the overnight chlorine test , but it seems to hold pretty well overnight when I test in the AM. If that's what it is. I would like to get my SWCG to start making the chlorine for me, is it too early for that?

Re: What do I balance first - pool start up
The overnight chlorine test gives a good indication of the cause of chlorine demand. Sunlight always consumes chlorine during the day. Over night, chlorine is only consumed cleaning up the water.
The process:
Test for FC and CC in the evening after the sun is off the pool. Be sure that and chlorine you've added has had a chance to disperse throughout the pool.
Test for FC and CC again in the morning before the sun is on the pool.
The clean up is done when you lose less than 1 ppm FC overnight and there's 0.5 ppm or less CC.
When the chlorine holds overnight, I'd start to bring up the CYA to the target level. Adjust pH and CH as needed.
As I understand, SWCG's don't work when the water's cold. Do you have a owner's manual for it?
What are your FC, CC, TA, and pH readings now
Re: What do I balance first - pool start up
So I finally did the overnight thing and I'm not losing any chlorine. Ph is around 7.6-7.8. TA is 120. I've turned off the SWCG due to cold water at the moment. I'm thinking to bring up cya a bit and maybe a bit of baking soda?

I think your TA is ok where it is. Follow your SWCG manual for recommended CYA level. Glad you passed the overnight test!
Re: What do I balance first - pool start up
Yay!
