Our new lake is doing very well you can see down into the water about 18 inches it looks great. My fatherinlaw went golfing and was talking to one of the grounds keepers and asked him how he got there ponds so clear and he told him about an aditive he puts in. It makes the water blue. Now I do understand what it does it filters sunlight to reduce the alge growth. But I don't know if this is a good idea for the fish. Any body out there who has used this product I would like to know what were your results. Thanks for any info.
