Excessive cloudiness after shocking

[Mayorb]

After the usual dose of cal-hypo shock, the pool turns milky white (can't see the 2nd step) and takes a day or more to clear up.
The water is properly balanced out.
There is some sort of reaction happening.
I have consulted the chem expert at my wholesaler but we haven't found a remedy yet.
My other pools are not having any issues with this.
Any ideas?

Can you post a full set of water chemistry results for the pool?

With certain pool chemistry conditions cal hypo can cloud the water for a period of time.

+1 to that.

Also adding Cal Hypo over and over eventually raises your calcium too high (which is likely what's happening now)

If you are determined to "shock" your pool, use liquid chlorine and the cloudiness won't occur.

A complete set of test results would give us more insight.

Calcium is at 280. CyA 50. pH 7.5. Alk 90.
I'm in Houston, so we get 36" or more rain per year.
This fresh water tends to keep TDS, CH and CyA in check.
Tabs, Cal hypo, and acid are standard treatments for the vast majority of gunite pools in this part of the country.
