Thanks for that info. Only read one other thread that had to resort to ALUM to fix them up. Was after the pool was only cloudy, with no green or brown evident.
I, too, was under that impression. But, if I recall correctly, they have passed the OCLT, even with the green/cloudy water. Seems a bit unusual for it to stay cloudy/green for an extended period of time after passing. Though No two SLAMs are the same.
