Greetings,
I drained and refilled my pool over the weekend. Prior to the drain, I started noticing algae forming in a few spots but with such a high CYA level I figured a drain was best. Because i wanted to drain and refill as quickly as possible to avoid the 95+ degree temp, I drained pool until sub pump wouldn't drain anymore and started filling immediately. So there was still some water at the bottom of the pool when I started filling. I also failed to backwash prior to draining.
After refill, I got my numbers in check and everything was running smoothly. Yesterday morning I tested my water after adding the needed bleach and my FC was at 78. Today, my test was:
FC: 2.2
CC: 1.6
pH: 7.5
TA: 130
CYA: 40
My pool is still as blue as it ever has been, but based upon the SLAM criteria I did not pass the CC test. I am somewhat surprised that I have to SLAM already since I have had my numbers in check since the refill. I am assuming that the reason is because I didn't drain all the water out of pool completely during my drain and some algae stayed alive and needs to be destroyed. Is that a possibility?
Because I caught this early, I'm hopefully that my SLAM length will be minimal. I just want to make sure I am doing this correctly since it's my first time.
Based upon Pool Calculator, I need to get my FC level up to 16 and hold it there all day. Do I need to hold it there even if my CC level gets back to normal on a test? Or do I maintain my SLAM level until I perform the overnight test?
I just backwashed my pool before adding my chlorine. Should I be back washing all day as well?
Any feedback is greatly appreciated.
