Hello! Thanks for your responses in advance. I have a 25,000 Gallon concrete pool. I am having trouble bumping up the free chlorine in my pool. I have added about 10 lbs of Clorox Shock over a span of 3 days, 18 lbs of Hardness Control, clarifier and a bottle of pink-algae (Pink -X) compound to get rid of water mold as told by local pool company. Yet, no luck. I have uploaded a video and an attachment from of chemicals tested. I am completely lost on what to do next. Advice from the local pool store is not being helpful. Thanks again.
