1st Pool + 1st Test Results: Confused

[AUSpool]

Given the high FC it’s safe to say that it’s producing just fine. It all looks fairly clean. It does look like the sensor has some buildup but I dont know what a clean one looks like. My V25 (still Astral) says to clean with a 10% pool acid (HCl) solution but that can be quite harsh. Use an industrial strength vinegar from bunnings which wont harm the plates. You just need to soak it for a bit longer and maybe a second time.

I believe this is your sensor circled in the pic below.

Fortunately no extra salt has gone in!

So you would recommend replacing some water in lieu of letting it come back itself over time?

Up to you. It’s kind of your dry season now isnt it? If it was mine I would bring it down to 7000-8000ppm with the no drain method and then let it come down on its own from there. I keep mine at 4000ppm.

Appreciate the advice thanks. And yes, to your earlier post I also had a suspicion it was the sensor.

Good work, yeh thats how it’s done. I would say your salt is very high. The previous owner was probably randomly dumping salt in as per shop or FB advice due to that low salt error.

That's my guess, too.

Also noted some corrosion at the terminals, and at one point on the inside of the cap (not sure what it is? a sensor?) so these are probably worth giving a clean once I get supplies.

AstralPool cells that sensor at the wing nut "flow sensor" I think it just detects when the electrolysis products are building up and glow must have stopped. It may also play a role in the low salt warning.

My old Hurlcon SWG (eventually bought my Fluidra and rebranded AstralPool Australia) that came with the house had the low salt light constantly on once water was below about 20°C. That sensor was also quite corroded. Luckily my pool store (good guy running my local store, very lucky there) warned me to ignore the low salt light (at a time where I had absolutely no clue about pool chemistry) and only rely on salt testing when adding more salt.

As long as you take care of your salt levels with the drop test, you can just ignore the low salt warning, and you should still get some good use out of that cell.

Regarding the salt test: Did you test the 4000ppm standard that came with the kit? Sometimes the drop sizes can be a bit off, and with higher salt levels this becomes more noticeable. In this case just "recalibrate" the ppm per drop based on the number of drops required for the salt standard.

Thanks for the tips. And yep, ran the salt test with the standard from the kit. See a couple of posts above where I discussed it further. Ultimately this gave me a revised factor of 160 (compared to the suggested 200 factor in the kit instructions).
