Indoor salt water pool, getting it balanced - crazy high salt levels

[Isaac-1]

If nothing is growing and the swimmer load is low in my indoor pool I loose about 1/2 ppm FC per day when the water is at swim temperature so expect it to take a good while to drop down from your current FC if you don't add hydrogen peroxide or sodium thiosulfate chlorine reducer.

I figured the same. Very low consumption. I will check again tonight. The owner is having at least 1/2 the water dumped, and refilled to lower the salt level. Hopefully in the next couple of days, so I don't want to adjust too much more now and just be throwing it out...

You know what I meant to ask too - what the heck is up with the pool store water test results?

Here's an example:

My FC reading: 20, pool store: 7.

My salt reading: 8000, pool store: 5500.

What the heck? I trust my TF100 fully. And I know I've read that pool store testing methods can be suspect, but THAT far off?

We have seen worse. Funny thing is if you take the same sample to three different $tores you'll get as many different answers.

It depends on the test they are using, for example if they are using a strip system with automatic reader the strips may be getting bleached out by the high chlorine level.

It may just be my cynical nature, but the pool $tore punches my account into their computer before starting the tests. I can't help but wonder if they look for recent test data before recording super-sloppy testing results.

"eh, he had 60 CYA 3 weeks ago. let's call it 66 now..."

Still waiting for the water swap out.
