Clear water but low chlorine

[pjku79]

Last weekend I came home from the lake and noticed there was a ton of oak pollen on my pool. My filter was clogged but still running. After spending 2 hours cleaning as much as I could out, I tested and noticed the Chlorine was pretty close to zero. I poured a half gallon of bleach in to get it back up and after a few hours running the pump on high and the robot, it cleared up. I bumped up my SWG to where I had been running at this point last summer (50% for 12 hours).

Three days later, I noticed it was starting to get low again. I didn't measure yesterday because I was busy and when I measured today it was down to 0.5 ppm. Should I jump right to SLAM or if the water is still clear, I can get it back up to where it needs to be.

I am thinking maybe I should SLAM because it did hit zero for some amount of time due to he pollen.

As always, thanks for your help.

SLAM Away, I do a SLAM if it gets below the minimum just to be safe... Just cause you can not see it yet it is coming... I love a 24 to 36 hour SLAM compared to waiting and have it go a week long

Just do an OCLT after 2 days and see where your at...

The Overnight Chlorine Loss Test will verify if there’s something growing.
There’s no harm in doing a SLAM Process especially since you know u have been too low on fc.

Thanks, I'll go dump a few gallons in. That is what I was thinking. Hoping if I nip it now, we can swim this weekend.

You can safely swim in a pool as long as the FC is above the minimum and at or below SLAM level based on your CYA. You must also be able to see the bottom of the pool in the deep end of the pool.
