Macro-zyme Pond Bacteria Enzymes Water Treatment for Muck, Sludge, Silt, Odor (4 x 8oz. bag)

Used product previously and satisified. This time one bag floated to shore and did not dissolve. After 2 weeks no obvious improvement. Previously saw results. Either ingredients have changed or quality control has been compromised

The product appears to be way past shelf life and water soluble bag that holds bacteria was deteriorated and falling apart in bag. Had to just dump in water from shipping bag.

Absolutely helped our old pond! I wish we could see the bottom to know how much it has improved but the water isn't full of tannins and there's much less muck!

All the bags were broken open so you couldnt just through them in the lake. I wasnt happy at all !!!
