So I've had to SLAM the pool multiple times this summer, but the algae keeps coming back a week or two after each SLAM. I've just re-read the SLAM page and realized I've been leaving the salt cell on for my overnight FC test (Doh). That's one mistake, but I want to make sure it's the only one.
I'm in the middle of another SLAM right now, and here's where I'm at:
-Began the SLAM Friday. CYA was at 40, got FC to 16 and have maintained.
-Over the weekend was checking FC 3-4x a day
-Today (Monday) was able to check it twice. This AM, FC had maintained overnight (with cell on) but I can still see remnant green algae in the spa that won't seem to brush off. Keeping FC at 16 tonight.
It's a big pool, 35k gal, so I'm using a LOT of bleach. I've literally emptied the two local Walmarts, and most of the local Target of their house brand concentrated bleach. However, that's what it takes to raise FC.
Should I be doing anything else? Would raising FC even higher help speed this up? I'm brushing the pool daily during the SLAM.
