Over the past three months Iíve been working with a local pool supply store and collectively weíve aggressively been trying to fix my green water problem. The manager of the store has been very helpful, yet the green water Ė algae problem continues. The pool is about 9000 to 10,000 gallons. Iíve spent about $300.00 is chemicals to balance the chemical issues and repeated testing at the local store shows the chemicals are in the water. The problem though seems to be that chlorine is quickly evaporating. One evening I poured 6 gallons of chlorine and 12 hours later I took a sample of water to the store and the results shows very little chlorine. Whenever I take a sample thereís little to no chlorine. Dumping more chlorine is not fixing this problem, it keeps burning off. The stabilizer is within normal limits. I had an old outdated filter so I replaced the filter with a Hayward 17502. The pump is a Flotech 1.5 HP. Hayward tech support said itís more filter than I need but will work since Iím seeing a reading of 2 PSI.
When the pool was clear about 9 months ago, I swam to the bottom drain and noticed there was no suction; therefore, only the skimmer on the side of the pool is functioning. I donít know how to clear the bottom drain.
Thanks in advance for assistance.
