Back at it trying to figure this all out as I'm now having to run it 19 hours a day. I just did an FC loss test today without the SWG running and went from 12 measured at 5am this morning, to 7 measured at 10pm this evening, for a total loss of 5 FC. CYA is a pain to measure so maybe I'm lower...

Is there any issue with adding Chlorine to the pool mid afternoon? Will it burn off before having time to mix in with the water and that's why it's advised to add after the sun has gone down? I'm at 5.5 FC when I just checked and we'll be having some swimmers today so I would expect it will...

Love it, thanks for all of that, I can appreciate the details. That's going to force me to run my pump about 12 hours a day at 100% which is a bit more than I wanted but not the end of the world. I've got my CYA up to 70 but I may consider bumping that up another 10ppm if it would help. I'm not...

I ran the SWG only overnight for 7 hours and only went from 6 to 7.5 in FC. Even giving it the benefit of the doubt and calling that 2 would be pretty low relative to expectations, but that would at least get me comfortable that my daily FC loss is considerably lower than what I had previously...

Good advice. I passed the over night chlorine test again with flying colors so no issue there. I'll do the SWG test tonight. Any recommendation on how long I need to run it for? I shouldn't need to run it all night like the ONCT I assume? 2 hours good enough? With the 25ml test what do you...

I see what you did there :LOL:. Good to know that its not crazy out of line. I'll do an overnight test with the SWG off and see what I get again, just to rule that out. Then I'll do another test tomorrow overnight with the SWG running to see what its actually producing all things equal, and...

I'm in process of trying to dial in a newly installed SWG (Circupool RJ+ 60). I wanted to test FC over a 24 hour period to see if I was getting any loss running the SWG at 100% for 10 hours. I tested after sunset 2 nights ago and got an FC of 5.5 and last night I tested at an FC level of 5 for a...

Walmart, pool essentials chlorinating liquid.

Looks like the date was mid May so recent. I think I'll need to adjust the pool size up.

We moved into a home that has a pool which I've not dealt with before. The pool company that had been providing the prior owners service told me it was about 30k gallons. I added about 325 ounces of 10% bleach expecting an FC increase of 8.3 per Pool Math and I only got about 6 to 7. Is it safe...

Very helpful, I'll do it again and see if I can get it right this time. Thanks!

Hello, new member here! What a great website. We just bought a house with a pool 4 months ago and I'm diving in head first. I've got the YF100 kit and speedstir and want to make sure I'm taking note of the right levels. I followed the directions as instructed but my question is, am I supposed to...
