Need hours

Went into the store with a water test told the person helping me that I have had Alage in my pool for three weeks. He did the test, after he went and got two things off the shelf and told me what I needed to do and when. He asked me to bring in a water sample two days later and we would make sure the pool was balanced. Sure enough after the second day the pool was clear. I went back into the store and the same guy set me up on what I need to do to keep it clear. It has been two months and the pool is still good. I would recommend them to anyone.
