BioGuard banish
While away for several days, my swimming pool chlorine level got too low, allowing algae to flourish. Subsequent chlorine killed the stuff, but some clung to the walls and could not be brushed off with a wire brush. I asked Pool Geek what to do; BioGuard banish was recommended. It worked!
