To increase CYA via granular stabilizer, place the required amount as calculated by the Poolmath calculator into a white sock and place in the poolside skimmer basket. For those concerned about suction flow to the pump, suspending the sock near a return jet or from a floating device will also suffice. Best never to allow undissolved granules to rest directly against the pool surface. Squeeze the sock periodically to help it dissipate. Once dissolved, consider your CYA adjusted to that programmed (target) level. CYA test readings should show a rise in 24-48 hours, however some pools may experience a longer delay to fully register. Best to confirm final CYA in about 5-7 days before adding any more stabilizer/conditioner.
Maybe use half at first. Let it mix for about 30 min and test again. I'd hate for you to go too high on the pH only to have to lower again for pre-SLAM prep at 7.2. The Walmart Clorox stabilizer is fine. They always have it in 4lb containers if you need more. But try to shoot for a CYA of 30 if you can so that your FC (bleach) requirement will only be 12.To raise the PH. And the pool math app is advising adding 10lbs to reach 7.2, does that sound about right?
You won't need a lot of muriatic acid, your TA & PH are low, not highLots of baking soda and some muriatic acid.
You can get the washing soda in the laundry aisle for a fraction of the price (2 Pack) Arm & Hammer Super Washing Soda Booster, 55 Oz - Walmart.comI'd like to start the slam process tonight so I'm going to head to walmart and pick up something to raise some PH and see if they have anymore chlorine in. It looks like I can get:
Clorox Pool&Spa pH Up Pool pH Increaser, 4 lbs - Walmart.com
And in PoolMath it shows 52oz of washing soda (or like 3lbs 8oz) for 25000galsTo raise the PH. And the pool math app is advising adding 10lbs to reach 7.2, does that sound about right?
You are doing great!Right, I made a typo or something earlier! I redid the math in the app before adding anything and broadcast 3lbsish in the deep end of the ph up. I’ve had the CYA soaking in thin hosiery for a couple of hours, it’s about 70% dissolved. Going to go squish it when I retest.
I added enough bleach as per the app late last night to reach 12, going to retest in a bit. It was super late so I didn’t have time to stay up and test after!
