Post-SLAM - what's next?

[Jenrudolph1]

Hello,

Thanks to some great help from TFP, we have completed our SLAM! 16 days and 29 gallons of 12.5% Chlorine later and we are clear, our OCTL was 0.5 and our CC is < 0.5




Now, the SLAM directions say to let the FC level drift back to normal. Got that. I will welcome not checking the levels every 3 hours LOL. But... we are scheduled to close the pool the second week of October. How low should I let the Chlorine get since part of the closing directions are to raise it to SLAM levels a few days before? (Our SLAM level is 20ppm for reference.)

Also, when can I get accurate readings on our other values - TA, pH, CH, CYA? I really want to be sure the TA and pH are in line before closing if that's possible.

I welcome direction on the next steps for the two weeks we have left with this absolutely gorgeous pool!

Thanks!
Jen

Until u are ready to prep for closing just maintain the high fc target for your cya FC/CYA Levels
No need to try to maintain higher - although at cooler temps/less uv less fc will be consumed daily so it may take a while for fc to come down from slam level.
Enjoy the break lol
The only test that you have to wait on is ph - fc needs to be 10ppm or below for that one to be accurate.
Ta & ch may sometimes be funny colors at high fc levels but the dramatic color change at the endpoint is what matters in those tests.
Enjoy your trouble free pool

Would my CYA test be accurate right now? We have backwashed and added water several times so I want to verify that ASAP. I wasn’t sure if that would be affected by a FC level of 20.
Thanks

You can test your CYA at any time to verify if it is the same or if it dropped from all the backwashes.

Not affected so long as the new water is circulated well.
