At pump startup - White flakes come out of each outlet for 2-3 min.
We had this occur 4 years ago when I had my pool tech taking care of the pool and I thought it was from high CH. I don't remember what the verdict was back then ... but the next year I found TFP and took control of my pool maintenance.
My chems have been decent all year - water is perfectly clear.
FCL - From 3.0 to 4.5 (the last 5 days = 3.75)
PH - From 7.6 to 8.2 (Last 5 days is 8.2)
TA - From 45 - 60 (last 5 days has been 55)
CH - From 130 - 150 (last 5 days was 130) I just added 20# of calcium chloride with the goal to be at 200. Up to 150 today.
CYA - fairly steady all year @ 55-60
Salt - 3400-3600
Temp - 84
20,000 gallons
I'm not sure if it is a combo of the A & H B-Soda (added 30# in the past 2 weeks due to falling TA (goal is 70) ... or the CC I added last week?
I have also been fighting a rising PH ... goal is 7.4-7.6 Pool math showed to put 32 oz of MA to lower my PH from 8.2 to 7.6. Put it in overnight - ran pump till AM and PH barely moved???
I know I'm fighting the fun battle of TA and PH interactions. I think I can deal with that ... but the flakes are a concern.
The last times it occurred in 2016 - we carefully checked the gas heater - no calcium buildup or flakes seemed to be coming from it. We also checked the IC40 - it's fins we very clean.
Any ideas or anyone else have this occur? If I didn't have a dark onyx plaster finish I probably wouldn't see it as easily.
