Hello all. My TA is high (175) and I would like to add borates. I know I need to lower the pH with MA and aerate to bring the pH back up, and repeat until the TA falls to where I want it. I lowered my pH a little to 7.4 and thought I'd bring it up to 7.8 or so before knocking it back down. We want to swim tomorrow, so I don't want to stray too far from norm.
I have a submersible pump I got from Home Depot that has a 1 1/4 threaded output. I rigged up a piece of 1 1/4 inch pvc so that I could sit the pump on the pool floor in the shallow end, and the PVC pipe sits about 3 inches above the water line, and shoots water out the top.
But I can't get the pH to rise. It's been running for a couple of hours, and I haven't seen it budge from 7.4. I'm tempted to let it aerate overnight, but slightly afraid it may be way too high if I do that when I wake up. What's going on here? Am I just not waiting long enough? Is my aeration method not working?
