Hi all, I've done a few SLAMs over the years and always had success, but this time seems to be different. I went through the process and it seemed successful. I have a pebble finish concrete pool 14,000 gallon. My CYA is 30 so I put the SLAM level to 12 and kept it there until it met the criteria of minimal overnight drop, less than 0.5 CC using Taylor FAS-DPD and water clear. I brushed and vacuumed and cleaned the filter daily and ran the pump 24 hours a day for the days. I achieved that three days ago. Today, here were my numbers:
FC - 7.2
CC - 0.0 all clear
TA - 60
Calcium - 310
PH - 7.6
Borates - 30
temp 84 degrees
The water looks very clear and the testing says it should be clean, but I noticed a couple patches on the bottom and when I brushed it, of course it seemed to be algae. The brush poofs it like a sandy greenish/yellow residue. Is this a situation where it simply got algae again? And how so if my chlorine is at the level it is with no CC?
Thanks for any advice and help.
