White flakes after additions

[iain42]

I recently raised my CH and CYA.
current levels

Does the salt cell need cleaning ?
Should I have turned swg off while Increasing cya and ch ?
It occurred to me as it can’t be a coincidence and I examined my swg two months ago...


thanks

Lower your TA.

I just looked through your PoolMath logs. One thing I noticed is that your TA readings are fluctuating between like 40 and 110, looks like something's not right with your testing.

I also noticed that a bit further back, your pH and CSI used to be quite high. That's probably when scaling accumulated on your SWG cell. Now that you seem to be maintaining lower pH and lower CSI, it's probably easier for the reverse cycle of your SWG to actually get rid of it, and it flakes off.

Do you see a lot of deposits on the cell?

I took a look at the cell and some of these flakes washed out.

Going to order a fresh test kit and test chemicals.

Thanks for the TA article. I will do this soon.

How much lower 90?

How much lower 90?

Even 60-70. TA 50 or above is ok.

Thanks I wanting to put it into my pool math app as a goal to shoot for. I didn't mean to raise TA to 110. I must have added to much.

OK I added some acid and it came down to 90 with a PH of 7.4.. I will start using the method in the article until I get a TA of 70.

Thanks for all the advise.
