I keep our pool open year round and run pump when temps fall below freezing. I live in Oklahoma and it’s been below freezing for over a week now; pump has been running the entire time. Oklahoma just announced rolling/planned outages (15 mins to 1hr); unknown when/if my area will be shut off...

So, my chemistry this morning free chlorine 5 Cc - 0 ph 7.8 TA 50 CH 225 CYA 30 During the day, fc may drop to 3.5 but at night I raise it back to the upper limit of target range for CYA (currently 30) if not a little more just because with high temps I want to ensure I maintain above...

Hello, Here’s my latest liquid chlorinated pool chemistry- FC - 6 CH - 225 TA - 80 (previously 100) ph 7.4 (previously 7.8) CYA 30 Last night I added 40 oz MA. My pool typically hovers around ph 7.8, sometimes a little higher whether my TA is 50 or 100 (or in between). I can reduce ph by...

Hello I went out of town and when I returned I failed an OCLT. So I’m on day 8 of SLAM. Yesterday, I passed the OCLT test but thought for good measure I’d do one more day of SLAM given temperatures around 100 last couple days and had some swimmers. This morning, I failed the OCLT again. is...

Over the last several days, I've noticed a chlorine smell around/near pool more in the evening than other times and my water is clear. My FC has not gotten below 3.5 or 4 and I usually add 2-3 ppm each day. My CCs have been 0 or 0.5. Swimmers skin/bathing suits also smell like chlorine after...

i'm not sure if this is the right category for this post but didn't know where else to put it. i've been reading posts regarding sediment/dirt on bottom of pool and in my case, even adheres to the walls at times. i was concerned it may be something more than dirt so just want to confirm that...

I've read several posts some dating back awhile regarding high ph (8.0 and even higher) and some seem conflicting or not as concerned as others. So, i thought i would start a new post just to see what responses I get for my situation. I believe my signature has the details but i have a...

Hello, back in the summer i had an issue with extremely high CYA which caused something to grow; i finally got by CYA down by draining/filling pool. i then did the "SLAM" and was able to maintain chlorine levels with other readings WNL. I now strictly use household bleach 8.25% to maintain...

Hello, A little background first - we purchased the home in April 2016; the pool was only 1 yr old (installed Summer 2015). It had a high (100+) CYA level. It took a full year to get the CYA level below 80. Most recently, the local pool store has reported our CYA readings as low as 30 (late...
