Test results post Dorian:
FC: 5
pH: 7.6
TA: 80
CH: 250
CYA: 20

Had to drain a little pool water in anticipation of the waters from Dorian. Refilled, brushed and vacuumed and these are my results.

Pool math tells me that my TA should be 80, which it is. My CH should be between 250 and 350, which I'm at the bubble of. I believe I'm okay with the exception of low CYA. However, for my future investments, does anyone have advice for where and what products are the best for Calcium Chloride and Stabilizer? There are a few methods, but I'd prefer to take your advice and stick with it from now on. I read pool school and am not sure where to get some of the recommended chemicals. Anything good at Lowes, Walmart or Leslie's? Is the clorox calcium hardness any good? And with CYA, I'm not sure what to use yet.

CYA is VERY generic and seems to be priced uniformly.......purchase what's convenient.

I would leave your CH will slowly rise, anyway.

The Chlorox brand is very soluble. I got mine from Amazon. Was $14.xx for 1 bottle. It will last me a long time with less than 4000 gallons. IIRC, the HTH brand is also very soluble. I think you may find either of those brands at your local big box store.

Some are less soluble than others, but if you squish the sock periodically, it'll disperse and the pump will handle the mixing. Keep in mind however, once you put it in, your FC should match the amount of CYA that you put in.

Put it in, assume it's in. Chlorinate accordingly. FC/CYA Chart

Use PoolMath to determine how much you need.
