Adding chlorine and acid daily

I do a full T-100 test weekly on my pool here in Florida, where it is 93* daily with 100% humidity. I make any/all additions that are called for. I go in the pool early in the day for a few minutes to cool off after our morning walk, so not a lot of bodies in the water. I do a pH and FC test daily, as recommended. I need to add 2 cups of both acid and chlorine each day. Is that normal? Should I make any adjustments? I have a 3400 reading on my Salt. Is there any other information that I can provide?

Hello and welcome. Can you post a full round of test results?

2 cups (16 oz) of acid daily sounds high. And 2 cups (16oz) of chlorine daily also sounds high, especially with a SWG. How long are you running your SWG for?

If you are supplementing with liquid every day, you either need to turn up the output on your SWCG or run the pump longer to produce more chlorine.

What is your TA? If your TA is high, it allows ph to drift up more quickly.

Curious as to why you added baking soda to raise TA so high? This is the reason you have to add acid daily I think. About 50 to 90 for TA is fine.
Usually when your TA is somewhere near that range the PH stabilizes a bit and rises much slower.

My TA last Wednesday was high at 100. I run the SWG 8 hours per day

I am adding chlorine, as the Pool Math app says to do so. Should I just be increasing the pool chlorinator?
Correct. Adjust the SWCG % generation and/or the pump run time so that the SWCG generates the chlorine each day that your pool consumes. Raise your FC to target range for your CYA first.

Yup on increasing swg time or %. The app knows you need CL but can’t tell you how much to increase swg.
According to logs your TA was 60 and PH 8 I think. No need to add so much baking soda at 60 I don’t think.

The plaster is not new and it is screen enclosed, but no roof to block sunlight.
I forgot about pool logs. Your acid demand is from adding unnecessary baking soda, not curing plaster. No permanent harm done. And I didn't see that yours is a SWG pool, I was comparing your usage to my same-sized pool. You shouldn't need supplemental bleach at all, but I think that's been covered now. .
