Pulse Supercharged Pond Bacteria (16oz)

Performed very well in a badly overstocked koi pond (9 twenty inch and 6 five to ten inch koi plus 4 6 inch shubunkins in a 400 gallon pond) and successfully kept ammonia, nitrates and nitrites at safe levels. My only complaint is in the packaging: both times I have received my order some of the contents had leaked out of the bottle due to caps that were insufficiently tightened.Edit 9/29: It's wonderful to find not only a company that offers a quality product but works hard to keep their customers satisfied. They are addressing the packaging issue and have gone above and beyond to make me a very happy customer.
