CYA was all dissolved when I got home from work, and I only lost 2ppm FC today! Much better. Does the CYA register immediately on the test as long as it's all dissolved? I measured right at 30ppm CYA this evening. It will probably be another week before the water gets cold enough to close...

Here's a few pics taken last night at about 6:45 after I put the first round of chemical in. Sent from my iPhone using Tapatalk

Ok, the results are in for the OCLT. At 6:30pm last night it was 2.5ppm FC, 0.5ppm CC and 7.8pH. I added 112oz of 10% Liquid Chlorine and some Muriatic Acid to bring down the pH. My in-laws next door added some water to bring up the level during the next hour, so I gave it another hour to mix...

I've never had the CC register more than 0.5 for this pool, however the last time I measured it was probably a week or so ago. I was measuring it every other day for the majority of the season. The only other test I've done recently is for TA which showed 150. Sent from my iPhone using Tapatalk

None of the local pool stores carry liquid CYA. One of the stores offered to show me how to make liquid CYA from powder using hot water. I'm a little skeptical. Anyone have experience with this? And does it work? Or am I better off just putting it in as powder? I plan to do the OCLT tonight...

What is the recommended frequency for brushing the pool? I didn't realize I should be doing this regularly I thought I only had to do it if I had an algae problem. Sent from my iPhone using Tapatalk

Now it's clear. You were talking about liquid CYA not liquid chlorine. Thank you. Sent from my iPhone using Tapatalk

Catanzaro, I understand what you are recommending as far as the OCLT to rule out algae, which I will plan to do tonight. I also plan to add CYA since I know it is low. I am confused about your last comment about liquid chlorine not being recommended. Your earlier post indicates it is what I...

Ok, I use a TF-100 test kit and I use the DPD test to measure the chlorine. Right now it's losing about 8ppm per day. Air temp has been highs in the mid 70s and lows in the 50s. I'm using 10% liquid chlorine, and I'm adding once per day in the evening. It was losing maybe half that when we...

This is the first year for closing the pool. I've read the pool school article on closing an AGP. My question is, what would be the effect of closing before the temp gets down to 60 deg? My CYA level is currently pretty low (<20) and I'm leaving the solar cover off to allow the temp to drop...

It's 99% according to the active ingredient label, and it was from a container marketed for spa/hot tub sanitation "SpaGuard Chlorinating Concentrate" a BioGuard product. I expected about 30ppm rise, which is why I was surprised when I measured <20ppm.

I've added 32oz total.

I tested twice, once indoors, and the second time outdoors in full sun, with my back to it. Both times I filled the tube, and could still slightly see the black circle at the edges. It never fully disappeared. Both tests were with Friday's water, so I will try again tonight or tomorrow with...

I had the same thing. Just set up the pool on 7/22 and used the pool school recommendations and added 8oz of dichlor for four days. I tested CYA on day 5, and I got <20, when I thought it should be just above 30 based on the pool school article, and the pool calculator. So just for...

Just set up our pool a week ago, and used the pool school recommendations for temporary pool startup, and now on BBB. We are going to be away for 2 days, and I'm wondering if I can simply over-chlorinate before we leave.
