I've been struggling with algae for weeks. I've dumped hundreds of dollars of chemicals into my 25,000gal in-ground with little results. Finally I broke down and took a water sample to my local pool store. $250 later they sold everything that I would need to get the water right and they reassured me that I would have crystal clear water in 3 days. With professional help I added 25 pounds of ALK up. 5 pounds of pH up. 25 pounds of calcium hardness. 8 chlorinator tablets. 5 pounds of turbo shock and last but not least one bottle of 60% algicide. I brushed the walls and floor, set the pump on flow 3 and sat back and waited for my water to clear. It has been about 48 hours and it has gotten worse! Is my filter working? I'm at a total loss and this pool has defeated me. What should I do?
