Persistent low pool pH

[CarlD]

Ben,
It's 30k.
If you can get 5 gallon carboys of 12.5% liquid chlorine it will be a lot easier to add to your pool. Just use 1 gallon of the LC where you were use 2 gallons of bleach. So you'd use 7 to 7.5 gallons of LC instead of 15 gallons of bleach--1.5 carboys rather than 15 bleach bottles.
Rest assured that LC is simply nothing more than double strength bleach. You just use about half as much for the same effect.

While they may look at you funny to see you loading 30 gallons of bleach in your cart, the pool stores will be HAPPY to help load 3 carboys for you...

Thanks! I haven't been able to find anyone selling carboys here. I can find 10% by the gallon at Warehouse pool. It costs slightly more than the 6% at the local discount store. I guess I can just give up my gym membership and get my workout loading and unloading bleach.

Why can't I use powdered shock, cal-hypo, to bring up the chlorine level?

Because, then you have to account for the effects of calcium and carbonates and hydroxides added by the cal hypo. It might be OK, but it might turn your pool in to a milky mess. Without test results from your K2006, we have no way of knowing.

If your calcium level goes much over 400ppm, your risk of a milky pool increases. All dry chlorine combinations have drawbacks. Cal-hypo's is rising calcium. Di-Chlor's is lowering pH and raising CYA. Tri-Chlor's is REALLY lowering pH and raising CYA, too. Lithium is insanely expensive and we have not seen or heard of it working any better. Only bleach/LC have virtually no side effects.
