OCLT shows loss of 1.5ppm - Time to SLAM?

[R1NLP]

HI everyone,

I noticed my pool started losing chlorine faster than before. The pool has been getting more use but to be safe I did an OCLT.
Last nights results showed FC @ 4ppm. This morning's test showed FC @ 2.5ppm. CC has been no greater than .5 at any given time.

The water is clear so I'm wondering - is this loss dramatic enough to require a SLAM?

Yes. Should be a quick SLAM Process since you caught the algae early.

YES! SLAM Process time! If the water is clear, it could be just a day or two of raised FC level.

Be sure to take a full set of tests before starting!
