Add salt???

[Jbarodin]

Chemicals were all good Sunday. Salt was approx 3100. Then suddenly yesterday my SWG said to add 147 pounds of salt. I added 80 this morning but it still says to add 107 pounds. Something doesn't seem right, can't see how it goes from fine to completely out of whack. Had some rain, nothing major.
Any help as always is appreciated

J,

After adding salt you should wait 24 hours before relying on anything the cell tells you about salinity. It takes that long for the salt to mix with all the water.

Plus, depending on the cell, the tolerance is +/- 500 ppm...

Thanks,

Jim R.

You need to have the salinity measured with a test other than what the SWG says.

For a quick measurement you could get some test strips and/or get a pool store test done. The best test kit for salt levels is the Taylor K-1766.

Once you get a reliable salinity number we can offer some more advice on what is going on.

I would enthusiastically suggest the Taylor salt test kit, #K-1766. My SWG's readings are always wrong compared to the drop method. Which SWG do you have? Mine does not tell me how much salt to add...just a instant and average salinity in ppm.

Thank you for the quick responses.

I took a sample to a local pool store to get a reading and everything looks good, all the numbers were fine, my salt was 3100. So I'm going to try cleaning the cells in the SWG and see if that works. First time trying this so wish me luck.

How old, what brand and what size of SWG do you have?

You can clean it easily if necessary. Acid into water 6:1. Rinse promptly when the bubbles slow way down. Hope you have an end cap.

Cleaned the cells, it was very easy to do so. They were very clean, probably didn't need cleaning.

I have an Autopilot, only 16 months old.

Press "Menu" it will say Test Pool Pilot, press "Select".

"Check system" red light still on, and still says "add salt" (now 107 pounds). But I've had my water tested and everything is in normal range.
Not sure what else to do or what the problem could be.
Thoughts? Suggestions?
TIA

Keep the SWG happy, add salt.
