Hi All,
I have a 25,000 gunite pool.

I've been doing the bleach thing for a while, and it has worked much better than the loads of powder I had been dumping in...but

I'm going through tons of it.
At least 1 bottle (the big bottle from WalMart 1.2 gallons I think) EVERY day, and sometimes 2 bottles just to keep any algae from starting. Even with that much it is nearly gone in 24 hours.

My pH is also high. Straight 8.0 which is the top of my tester's scale, so it could be even higher than that.

I presume the high pH is hurting the ability of my chlorine to do its thing...

So I need to drop the pH with muriatic acid, right?

How much do I put in at a time? That stuff is nasty. I don't want to make the pool unswimmable by putting in too much. I put in about a quart and it had no effect on pH.

So how much acid do I add at a time?

Thanks in advance.
