Hoping to hook up my acid and chlorine injection pumps this weekend, and while the best return point for the chlorine seems obvious, (the floor cleaner heads, since that way the new chlorine will be swept over all the plaster surfaces first), I don't think I want to put acid over the plaster...

Our newly plastered (6/26) pool, while generally quite smooth (sort of like leather), has some rough areas near the edge marker tiles, I think due to being roughed up by the sponge as the plasterers cleaned off the tiles. We are steadily brushing, but it seems to have little effect on these...

I am one week from plaster, and trying to decide between two plaster additives that both claim to improve white plaster: Silicone Shield, and RPM, a silica fume product from Triton. Any experiences with either would be great to hear, particularly longer-term. Anybody used them? thanks, Bcatv
