Been lurking here for a while, invaluable information learned and still learning. Just recently built a new house and a pool at the same time. Pool has been completed for a few weeks now. Received my TF-100 test kit and here are my first results:

FC 0
CC .5
pH 8.2+ (just added 89oz of muriatic acid)
TA 150
CH 275
CYA 0
SALT 3000

Via my control panel the chlorinator is set a 50% and my pump is set to run full speed 6am-4pm and low speed 4:30pm-7:00pm. Need some direction on where to go from here.

Thanks!

Hi Josh and welcome! :wave: Congrats on the new pool/home. With no CYA, the sun grabs your FC right away. New water has no CYA (stabilizer) and you need some quickly. For now, use the Poolmath calculator to increase the CYA to 30, and get some bleach in there ASAP. Use the bleach to achieve an FC of 2-3 ppm. Tomorrow, once the stabilizer is in the water, increase that to about 5 ppm. With a SWG, we normally suggest a CYA of 70, but because your water has been unprotected for weeks, I'm concerned about algae - even if you can't see it. So I think it's best you take the CYA to 30 first, increase the FC to about 5, and then consider doing an overnight loss test. Pool School - Perform the Overnight FC Loss Test (OCLT)

If you pass the OCLT, then increase the CYA to 70 and your FC should hold much better with the SWG. Also tomorrow, double-check the pH to make sure you got it down into the mid-7 range, or at least under 7.8. Hope that helps, and nice to have you with us.

By the way ....... THANK YOU for being a TFP Supporter! :goodjob:

FC 3
CC .5
pH 7.8
TA 120
CH 120
CYA 30
Salt 3200

Going to increase my FC to 5 and thinking that I will run the OCLT tonight. Battling pH with a new plaster pool is a constant fight huh?:confused:

FC dropped 4 points overnight, needs to SLAM. I'll address pH this morning and then start. Since I'm at CYA of 30 I need to aim for a 12ppm shock level even though I'm SWCG?

That's correct. And for now, I'd just leave the SWG off since it's not designed to maintain such an elevated FC level. Just use "regular" bleach. Nothing splashless, or scented. You can use the Poolmath calculator for dosage help. Good luck!

FC only dropped to 10.5 overnight, I hope this will be my last day! Scrubbed skimmer and both lights and their associated tubes. Don't see much of anything that I would identify as algae.

OCLT test passed lastnight! FC was 11.5 this morning and CC was .5. Re enabled the salt cell and will re adjust pH and add enough CYA to get me to 70 this evening.

So here are this mornings test results:

FC 4 (adjusted to 5)
CC 0
pH 8.2 (adjusted to 7.2)
TA 80
CH 275
CYA 60
Salt 3200

I need to pick up more CYA and address CH next I assume.

FC 6 (turned down SWG 5%)
CC 0
pH 8.2 (adjusted to 7.2)
TA 70
CH 275
CYA 60
Salt 3200

So since I'm a new plaster pool pool math tells me I need to add 23lbs of calcium chloride. Broadcast in the deep end even with that copious amount needed to raise CH?
