I would not call it a "healthy growth"...this type of algae is considered a nuisance algae and it might be a good time to investigate its cause before you have a full blown problem. Also question advice given to you by your LFS if he calls it "healthy growth." It is not toxic or something, but generally an indication that water quality, lighting or something is off.
