Product review (1 stars): Does not perform as stated
I bought this product based upon the reviews on this site. I can tell you, after having purchased it and followed the instructions regarding dosage, aeration, filtration, and cleaning that to date, the product does not work at all. My pond is still green as can be. This product appears to be nothing more than water with blue food coloring in it. Prior reviews must have been written by company spokespeople, because this product does not work as stated. I cannot tell any difference at all in the water purity. Please don't waste your money like I did.
