Our pond is 7 years old . We have 2 aerators and one fountain. We buy 2 of these and put one each by each aerator . Blues gills are doing great and pond is very clear and clean . Review: Seems effective. Pricey, and the block can break down to a powder if you store it - Works well, but it's pretty expensive. Our pond is small, and even at twice the recommended dosage, we didn't use it all in one shot. By the time we put in the second dose, the block had broken down to a powder and was much more difficult to get to the places in the pond where we needed it. I'm not sure if this affected it's effectiveness, but we did switch to another slightly cheaper "pellet" brand for easier distribution. If you've never used this type of stuff before, be aware that this is a bacteria, so there is an odor to it. ## Features - Pond Muck and Sludge Remover: Kasco’s Macro-Zyme Muck Block pond equipment is the perfect choice to control and eliminate sludge and foul odors in tanks, ponds, and lakes.

Results are best when the application instructions are closely followed and when the pond has an aerator or water fountain running in it to assist with maintaining good pond health.

Thank you and enjoy your pond! **Q: Have an acre pond how offen do you put these in how long do they last?** A: I think varies a lot.
