Our pool pump broke and in the time it took to get it repaired, we developed a "severe" algae problem. We went to our pool supply store and was sold Super Soluble and Banish (Bioguard products). We followed the instructions to the letter and things seemed to be improving. We were concerned after about 4 days that the progress seemed to stop. We were told that it was a time factor involved, that it would take about a week. After a week, we saw that the green started to redevelop. When we took another water sample in, we were told that the problem was that there wasn't enough chlorine. This was very frustrating, because in all the instructions that we were given, we were not told to continue to use the chlorine sticks. Perhaps, it is well-known to always keep the pool chlorinated, EVEN DURING TREATMENTS, but we are first-summer pool owners. I really feel like they should have told us to keep chlorine in the pool. We just assumed the chlorine would interfere with any of the treatment. Now we've been sold flock and shock to treat. We will be vacuuming the pool (on waste) tomorrow to remove the sediment from the flocking. I am hoping that this will resolve the problem; however, I am willing to accept any advice that any more experienced pool owners my have.

By the way, we have an in-ground, vinyl-lined, 18 X 36 pool. I do not know the make of the pump, but we use a Hayward Sand filter. Our pool is about 24,000 gallons.

Please let me know any additional information you may need.

Thanks, in advance for any help provided!!!!
