Here were my test results after pouring the concrete decking around the pool 2 days ago:
Yes, there were small, slight little blops here and there...nothing major at all. Very little wet concrete went into the pool...A couple super quick vacuums in the gathering spots and that was all she wrote! I backwashed the sand filter thoroughly.
Trying to lower my TA I chose Acid to also drop my PH and then I plan to raise the PH back through aeration. That's the ultimate goal. However, my TA is stuborn and hard to lower. I've already added over twice the Acid amount the pool calculator said and it's still not where it needs to be. I'm wondering if I'm missing something? Does the CH (which is high) have anything to do with the TA levels or not? With vinyl do I even need to worry about my CH at all?
I used the Pool Calculator for my 22,000 gallons and it said to add Acid 318oz of 20%, so I put in 2 gallons very slowly w pump running... etc. I waited 8 hrs, rechecked and got:
I put 2 more gallons of ACID in that evening since the TA was not down enough and the PH didn't drop enough either.
The Acid is new stock to our Hardware store, they sell a ton of it...not sure if it loses it's strength like bleach, but this junk I'm getting is strong...it'll burn your nose hairs from two feet away!
TA is still high at 140....???? WHY???
I just bought 2 more jugs of ACID and am waiting for further instruction before dumping it in!
I'm sure I need to reread pool school articles, I do that with every new issue that arises, but the kids want to get in the pool and it stays so busy that I need to dump in something to fix it and let it circulate so my kiddos can swim all day!
Any advice will be Great!
The pool water is crystal clear and we've had no issues at with the look or feel of the water since we first filled it in June.
