Adding CYA:
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.
Aeration works better at higher TA. Without knowing TA, there's no way to guess if aeration alone will get the pH up or if it'll need some borax, or if it will need to have baking soda first. As with all things here, test results tell us what we need to do.Thank you all! Exactly what I've been looking for!
Richard: as for the kiddos - 15 and 18- getting in the pool immediately is not of much concern. We've been awaiting the pool install for several months now, so a day or two more won't hurt. We all want it right before we start enjoying it. That being said, thank you for quantifying why people are saying to add chlorine first. This clears up some confusion.
So - If I'm looking at Pool Math correctly, once I get the pool filled and circulating, I need to add the 3lbs 8 oz of CYA (per PM for 30ppm) into a sock to begin softening, and then begin to add around a quart of liquid chlorine to get things started (around 1-2 ppm as Texas Splash suggested). Then on day 2, when the CYA should be completely dissolved and at 30 ppm (test to confirm of course), begin to add chlorine to get to 4 ppm, and then test and correct PH and TA if need be, correct?
I have a small test kit for chlorine and PH, so I tested my source water Sunday and I know my PH is at 6.8. I plan on aerating the water as it's going in to try and raise it some. I'll have some Borax on hand as well as some muriatic acid should I need to adjust. Chlorine is minimal and if I'm thinking right should be mostly gone by the time the pool is filled.
Am I on the right track?
Hey, you're not on a well there are you? Just thinking about iron in some of the rural areas.
With 6.8 pH fill water, it is highly likely you have low alkalinity. Don't be surprised if you need to add baking soda, like Richard said.
