Hmm. So why use CYA if it doesn’t protect from the sun?

It doesn’t? It seems like if I had 2ppm FC unprotected by CYA that the sun could eat up before hitting the protected FC, then adding more FC would just allow the sun to eat more FC before hitting the protected stuff?

Thank you all very much for your advice and help. Good call on keeping it in the upper range, I’ll probably do that, even though it seems like the sun will eat up most of that!

Update: Pool is beautifully clear and looking great. I let FC drift down to recommended 6ppm at 50ppm CYA. I’ve been keeping FC at 6ppm and it’s basically costing me between 20-36oz of liquid chlorine every day! Is this normal? It seems like a ton of time and money to have to test and add every...

Hopefully the last update! OCLT was at 18ppm last night at 8pm and at 17ppm this morning! So hopefully that means I am finished with SLAM. So, if I am done, do I let the UV eat the FC down to my recommended level now? Also did another CYA test yesterday and the result was closer to 40 than it...

It was what I had on hand on Saturday. It better not have any CYA in it, since the packaging says it doesn’t.

Yep using liquid ever since the first one. It’s incredible how much FC the UV rays eat up

Oh also, pool is crystal clear with no green dust when I sweep or anything anymore.

Update on the Slam: Recommended FC is 20. Used granular chlorine to get it up that level. Started on Saturday. During the day FC levels are dropping to 10, which I bring back up 20 about midday. Last night/this morning did an OCLT and lost 2ppm of FC. So close! Tested this morning and FC was...

You think it’s going to require it? Is the green dust a sign?

Update! I started with 41” of water in the pool, so I drained down to 20”. Refilled overnight, ran the filter this morning for 2 hours then tested. FC: 5 CYA: 50 pH: 7.2 TA: 90 Now we are cooking! I added 10oz of liquid chlorine to bring it to the recommended 6 on pool math and brushed it...

Holy Crud. Drain and fill twice would suck

I did and I actually think it’s nearer to 110. Drain the pool here we come! I got to this number because I didn’t have the test before, and I was going out of town for 4 days. A friend suggested that my CYA was probably 0 since I had never added any CYA (which wasn’t true since I used pucks...

TF-100

Ok fantastic so my FC loss isn’t out of the ordinary. Good to know thank you
