New Pool start-up & 3M Colorquartz

[bradjo]

Thanks mshumack! As I understand it the entire point of the higher acid is to remove the white plaster layer obscuring the quartz aggregate.

I've been cleaning around out there while the pool finished it's fill (it's now completely done) and took my first pool water test.

pH 7.8
ALK 100
CA 200

I brushed the plaster once (boy is that a job!) and then slowly added 1 Gal of Muriatic acid around the pool with a glug to the spa. Of course I then realized I should have added the acid then brushed but I'll get better!

Anyway as I was looking at the plaster I realized that my plaster shows a goodly amount of aggregate and the color is right (for me and hubby) so I think I've decided to forego dumping the pH waaaaaaaaaaaay down to 6. I just can't see taking 2 years off the plaster's life when we are both happy with the pool's looks and there's no really obvious streaking!

I'm going to wait a couple hours then test the pH again and see how much movement 1 gal of muriatic gave my 25,000+ gal pool. Then based on that and the alkalinity change I'll decide how much more to add.

I'll put the DE in the filter and start it later tonight or tomorrow sometime I think and then add chlorine in a few days.

I'm in the Mojave desert and we are currently 100+ by 8am and over 110 for high noon on so I'm worried about that! I also have to install a heater bypass before I run the pump if I get down a little below 7 I want to bypass my heater. I'm wondering if I need to start running my solar at night to reduce the water temp. It filled at 82 to 84 degrees and I'm worried that it could get way to warm from just the sun. I wonder what to warm is before the plaster begins to delaminate? Anyone have a number?

Thanks so much for the answer and I'll update as conditions change! LOL
