I did a SLAM last week as I had some light algae (see calcium levels thread), and it all cleared up nicely and my FC level is holding overnight but I've noticed what appears to be algae again on the grout lines. Won't brush off with the pool brush, but comes off with a sponge.
Is it possible to have algae with FC levels holding? Last FC test showed 17.5
I'm assuming it's algae, I have no trees or other litter falling into the pool.
