So we have had a ton of rain, I've been busy prepping for vacation and haven't paid as close of attention to the pool as I should be. Last night I raised the chlorine level as we have had a ton of rain. I go out this morning to test my water one last time before vacation and notice a ton of maybe dead algae on bottom of pool. So I dose it again and give it a good brushing. Is there anything I can do at this point to not come home to a green pool. I leave at noon today??!?!!?
