Me in blue:
OK - I can't even talk about the run-a-round I got today from the pool/plumber guy. Maybe in a day or two (sorry).
Deep breaths.
I'm dosing the pool twice daily with 10% chlorine from home depot. The date on the box is 18200 which I believe is July 20th. Yesterday I took a sniff and the chlorine smell was extremely weak, our regular laundry bleach smells stronger. When I use pMath and check it 2 hours later, the dose has hit the mark of FC 7.0 but within 4-5 hours it's hovering at 3.5. My CYA was at 30 at first but increased to 40 a few days ago and remained at 40.
Well, date isn't everything. It's how they stored it and transported it, too. If it's been exposed to a lot of heat, it could be compromised. But if you got a correct FC level out of it at any point in time, then it's probably OK. Are you testing CC? Lets see if you have any lurking chlorine eaters. Maybe even do an Overnight Chlorine Loss Test if you're concerned about the amount of chlorine you're using. But it's hot and your pool is going to use chlorine. This is your first August, right? Maybe that's just what your pool needs.
I called Leslie's and they told be their liquid bleach was 12%, but when I got there the box said 10%. I was unsure about the 90% "Other Ingredients" so I did not buy it. When I got home I do see that the HD box said the same thing. So the price is almost twice as much at Leslie's, not labeled any stronger - but probably less deteriorated than HD's.
I think the 90% is water, but another here will have to confirm. You can't buy 100% LC, it's not stable.
I see Walmart carries 10% as well for about the same price as HD, I'm sure they do not store it outside - unfortunately all Walmart's near us are out of stock.
I know I have new pebble that's just 1 week old, but I'm dosing the pool twice day (total of about 100oz.) just to keep it between 7.5 or 7.2. Does that sound normal?
OK, I think you switched there from talking about chlorine to talking about acid, yes? Do whatcha gotta do. Trust the test kit and PoolMath. I like the sound of you checking and dosing twice a day. Keep it up if you can. Eventually your acid demand will come down. And in a few weeks you'll be on SWG, so your workload will diminish. Every pool is a little different. But now you are seeing, if I may say, why I was pushing you so to take this over, even during your first start up. You just can't maintain proper pool chemistry, especially in the first month of a plaster/pebble pool, by showing up once or twice a week. Now that you are doing it, it's getting done right. Good job!
I did see that Leslie's has 31% MA for about $6 a gallon. I think I'm going to switch to that.
I buy my acid from Leslie's, and sometimes chlorine, too. That's the two things they sell that makes me glad they're in business. If you buy often enough, they'll figure out you're not one to be bamboozled with their magic potions, so they'll leave you alone and just sell you what you ask for.
OH ... the plumber/pool guy (used to be their pool guy), questioned why they had not added salt yet. I said that the plaster was only a week old, he said well you just can't use the heater. I NEVER read anything about adding salt that soon.
And this is why I warned you about being adamant that no one else add anything to the pool. Period. They might mean well, but they could throw something in to "help you out" and mess up what you've accomplished. A pristine startup with nothing added to your pool that it doesn't need!!
