Thank you for taking the time to look for that. The 12.5% at the pool store has a Jan 30 2024 date stamp, and has been on par. I have one gallon left, and I think it will get me through today and tonight's OCLT. I will drive out there and check the dates. Definitely will save me some money if today's process doesn't cut it.
Spent the morning since my post cleaning.
I couldn't find the key for the light covers. I don't want to force it and chance breaking the light or the sleeve. I dipped a narrow headed nylon brush in some bleach and got into the nooks as best I could. I will order one from Amazon or Jandy if tonight's OCLT fails.
I took the eyelets and threading out of all the returns, washed them in bleach, scrubbed them, scrubbed the inner threads of the return sleeve, and put everything back together. One eyelet out of the three was pointed a little high - I use this one to push water over the sundeck shallow area. It's a balancing act between too low to push water where I want and too high and disturbing the surface.
I managed to carefully pop off the skimmer plate cover. No visible algae, mostly brown staining. It got the same treatment as the eyelets. The face of the plate did have some white sealant on it. Mainly around the stainless screw heads, but some smeared across the plate. Some peeled off and some of it disintegrated into a cloud.
I scrubbed the inside of the skimmer mouth, neck, sides, the weir door (front and back as best I could. I don't know how to remove this. The back has some sort of foam float that isn't Styrofoam).
I scrubbed the critter cover plate for the skimmer (it's a wife thing...) and disassembled the floating thermometer that resides in the skimmer and cleaned it.
I used the big pool brush and brushed all the horizontal surfaces and walls again. Then I got back in and hand brushed the shallow sundeck, steps, benches, and waterline. I got as deep as I could hand brushing on the deep end benches without submerging my head.
Hopefully the extra scrubbing and mixing the water helped get to any dead spots.thin
Oh and turned the lights off for now, and had only 2 or 3 bugs in the pool with a few in the skimmer sock. It is about time for a blackout anyway since termites will probably be swarming soon.
