How to stabilize my PH

[Watermom]

I'm going to ask Ben to take a look at your post and see if he can offer some advice.

As far as I know "White Scale" is a term with no particular meaning, except the obvious one.

I'm *not* a plaster expert, but I know there have been problems with colored plaster almost as long as there has been colored plaster. And, if there's ever been any agreement on what the causes were, I haven't heard about it. All I've seen are these circular accusations: "It's the colorant! No, it's the cement! No, it's the plasterer! No, it's the homeowner!", and so on.

Blaming the homeowner - which might be valid, but I don't know - is popular, since they aren't in the trade.

Bottom line: do what he says, no matter how much acid it takes, so you'll be able to blame him.

Oh yea, CYA will not help stabilize pH.

Good luck!

This is a salt pool so having the CYA higher WILL lead to better pH stability because there will be less ougassing of CO2 because of less cell on time. 30 ppm is too low for a salt pool.

Also, dropping the ALK to 70 ppm will also help. However, it will get there on it's own fairly soon if you keep the pH at 7.2 for a while to dissolve the scale deposits.
