White flakes in pool

[TeenaTeens]

I just noticed white flakes in my pool. I super chlorinated this morning for 4 hours. We were in the pool yesterday and they weren’t there.

I checked the SWG, it’s clean. I checked the filter (cleaned a few days ago - still clean, but I swapped the cartridge anyway). Pool is balanced - tested this morning in fact.

Help!

I tried to catch some, but I can’t. There’s not a huge amount - but enough that I’m worried. I’ve turned the filter back on high.

Lower your pH to 7.4. Do this every few days and get the TA a bit lower. The SWCG is shedding calcium scale.

Also I’ve never cleaned the cell with anything but water. It’s just always perfectly clean each time I take it off. Not sure if that’s my problem.

My TA is 80

 

[mknauss]

Great. Get it lower.

My TA is 80

I thought that was perfect. CSI is 0.07. What should I have the TA at and the CSI?

I’m doing it now BtW - just tell me what to lower it to and keep it at. I thought 80 was ok. Live and learn!

Until the scale stops. Elevated water temperature increases CSI. The flakes are a sign CSI is a bit high.

Ok. So better just below 0 than just above?

Our water is heated every day to 88 so maybe that’s the problem too.

Yes. You are at that fine line of CH with high water temperatures.

Ok I will drop it down to 60 and keep it there. You are always so helpful - and your advice always works! Thank you so much.

Sorry one more question - my CH is ok as it is?

Flakes are gone! I will continue to lower the TA to 70 and now maintain it between 60-70 moving forward. Slightly negative CSI rather than slightly positive. But as close to zero as possible. Once again thank you for your help - I never stop learning with this pool.

Lower to 60 - it currently at 70.

Just waiting for the Ph to come back up to do it again.
