      This product is very concentrated and so don't need to use very much but you do need to use it on a consistent schedule. I suggest weekly as does the label. Algae can be very hard to get rid of once it takes a hold of the pool. Seems to work on yellow and green algae equally well. So I have been pleased with it and I like having extra product on hand.
