White Flakes resurfaced pool

[clone1008]

I recently had my pool resurfaced with an exposed aggregate. I am at the 30 day mark and just took it back to SWG. I am noticing white flakes in the Polaris 380 bag. These fizz when I drop Muratic acid on them. My test reading are as follows:
Water Temp 82 deg.
FC 4.0
PH 7.8
TA 80
CH 300
CYA 60
Salt 3200
CSI -0.09
LSI 0.3

What should I be concentrating on to eliminate the flakes?

The flakes are coming from the SWCG. You show a CSI below 0, but the parameters are such that the cell is still creating scale.

I would suggest pushing the TA lower if at all possible. That is best bet. Or add borates.

My CSI is below 0 at -0.09. How much lower should I take TA?

You might find just lowering it to 70 or maybe 60 will reduce/eliminate the flakes.

Ok I will give that a try.

Ok so TA is now at 60 and PH is 7.2. Should I aerate to raise PH or just let the SWG cell do it?

That was quick.

pH will rise naturally. The SWCG does not raise the pH.

I thought the off gassing of the SWG cell has always contributed to the rise in PH. As far as being quick on the reading, I waited an hour after adding acid and tested.

The hydrogen bubbles may add a very slight form of aeration, but the majority of pH rise is due to aeration from water features, wind, and adding high TA fill water due to evaporation.

Ok, no water features on my pool and I have the return jets aimed so that there is just a slight ripple in the water to create a vortex motion to the skimmer basket. I haven't had to add any water lately due to a lot of rain here in Florida. So I didn't know if I should bring PH back up quicker because CSI is now at -0.82 (Corrosive) with the new TA and PH readings.

I hate to chemically raise pH when it is in the 7's. Your CH is a bit low for Florida. I assume you have to add that pretty regularly.

Up to you. The CSI for a short term at that level is not an issue.

The question was should I aerate to raise PH, no chemicals involved. As far as the CH the pool has a new exposed aggregate resurface so I have been slowly raising it to see where it wants to fall.

Aeration is fine
