I had a pool maintenance guy check out my broken filter the other day and he told me I could start tackling my green pool while I serviced my filter. He said I could set my multiport valve to recirculate and start adding chlorine to kill the algae and get things blue again. He then recommended using floc on recirculate and let it settle and then vacuum to waste. I know that floc isn't usually recommended on tfp because it can gum up your filter, but since it's not currently part of the occasion would this be an OK way to clear things up?
