Pool company guy screwed up...

Be more aggressive lowering pH to 7.0-7.2 rather then 7.4.
@mknauss said 7.4 so that’s what I was doing.
What is the TA of your fill water? You have an autofill on your pool?

Confirm you do not have a heater.
I’ve been meaning to test my fill water TA... haven’t done it yet. No auto fill on the pool.

I do have a heater - sorry it’s not in my sig. Will add it later once I can check the model.

Would prefer to not drop pH below 7.4 as the CH is on the low end with a plaster pool.

The minor scale from the SWCG is of no concern.

Here’s another one... when we moved in the pool light and spa light didn’t work. We quickly diagnosed that the GFCI was tripping every time the lights were turned on. Since then it’s been diagnosed that the pool light comes on just fine when the spa light is disconnected, so the spa light must be tripping the circuit. Was told that’s likely due to water leaking into the light and the only option is to replace the whole light fixture (not just a bulb). Was quoted $300 for the new fixture plus installation. Thoughts?

What brand/model of light is it?
I truly don’t know, sorry. Just trying to get a read on whether replacement is the only/primary option. Obviously if that doesn’t fix the problem I’ll make them take it back.

I’m also losing about 0.5 FC a day right now with the SWG on. It’s running 13 hours at 100% so considering running it longer. Could low(ish) salt levels also lead to suboptimal chlorine output?

As long as the SWCG is generating chlorine, your salinity is fine. Salt level in the water does not change chlorine output.

13 hours is on the low side for your size pool and SWCG . Closer to 16-18 hours would be normal.

If the light is an Intellibrite, Globrite, etc, then the light and cord are one package. Though tripping a GFCI implies a wiring problem on surface.

I will adjust 0.5ppm up based on pool math!

Are you suggesting that replacing the light fixture won’t solve the problem?

I would be sure the wiring is checked at the junction box first. I am assuming the light is a small in diameter, LED light. They come as the light and cord as a package.

No paperwork on the light available at all? A picture?

I think wiring was checked at the junction when they unhooked it to confirm that the pool light was working fine.

This one for $300 is not LED. The LED light was quoted at $750.

I’ve attached a picture of the non-working spa light and the working pool light for reference.

Yep, he poured the CYA right into the skimmer over the basket. I won’t backwash for a full week then. He should’ve done the panty hose method instead? Just want to know the right thing to do.
When did he pour the CYA into the skimmer? While it was on Rinse? Cuz if so it's in the ground not the pool ;)
