    Do I need to continue to slam?

    Trying to decide if I need to continue to slam and for how long?

    Pool readings have been pretty stable: FC - 6, PH - 7.5, Alk - 130, CYA - 70; but I noticed pool has not been as sparkly as usual, kinda dull looking and few waterbugs in pool so checked CC and it was 0.5 and OCLT - 1. Still decided maybe I should go ahead and slam and started last night. Scrubbed pool walls, floors, steps and this morning pool looks great, sparkle is back. So I was thinking great no need to continue to slam, but then I noticed a few dark brown spots on 2 noodles we had left in the pool and in looking closer noticed a few of these spots on steps. I'm assuming algae? Scrubbed pool again, but wondering if I should continue to slam even though I do not see anything else at this time and for how long?

    Go ahead and continue to slam today and run an OCLT tonight. As long as you are seeing algae the pool is not clear.
