Thanks for all the help Mdragger88, Mknauss, & batesjer! Happy to report that yesterday morning, I passed an OCLT (holding a 23ppm FC level from the night before), pool has been very clear and less than 0.5ppm of CC (the FAS-DPD test for CC turned super slight/clear pink (barely pink at all...

Mdragger88, thanks again!! Just tested at 19ppm, going to NaHypo up a little for the night run. As always, thank you for the very helpful advice!

P.S. my buddy suggested a clarifier to clean up the remaining cloudiness, any thoughts?

Friend of mine with a pool had an old black dot test (no titration) where you mix pool water with solution and push the stick down until you can’t see it. I’m not confident of the accuracy, but it was in between 40-50, but the scale isn’t linear, so guesstimate 45 for CYA. Pretty close to pool...

Accuracy, as they say, is in the eye of the beer holder 😉 I think flying blind is a little extreme, isn’t it? I have an hth strip that suggests 40-50 is about right, backed up with several pool store tests suggesting the same range (3 times). If I err on the high side wrt to NaHypo and CYA...

mknauss, I don't have a CYA test kit. I rely on a combination pool store tests and HTH strips. It seems like it's tuned in pretty ok now, but before July, it was registering WAY high on the HTH strips. Pool store measurements where totally off early on. Given that CYA levels won't change unless...

Mdragger88, thank you for the video! That's how I overboarded half of my water last time. I used the shop-vac hose that I have in the garage. Good to know that I can use that method to vacuum "to waste" as well, I hadn't thought about that! My current vacuuming setup is a garden hose variety...

Mdraggger, by your last comment about vacuuming to waste, do you mean just drain it all and start over?

Mdragger, thank you very much for the feedback! Honestly, I thought once a day was good enough. 🥺 Would morning and just after sun goes down suffice? Whats the reasonable frequency of checking? Also with the Taylor kit, can I use 5mL of water and count each drop as 1ppm (how much powder, just...

Hi there TFP folks! Name's Matt, I'm a newbie (both here on the site and as a pool owner). I've lost faith in local pool store folks, they only appear to want to sell me chemicals (and lots of em!). I've been silently following the prescribed SLAM instructions on this site. I'm an engineer and...
