Cold Water Beneficial Bacteria ⅓ oz. Blocks - Fall Winter Maintenance

Product does a great job breaking down leaves and fir needles and helps reduce sludge. Regular weekly use adding tablets has substantially reduced the need for manual sludge cleanup.

I use this weekly all Winter to help keep my water parameters stable and the water very clear. This video was taken through the feed window of my Winter cover. The pond is 5 1/2 feet deep at this spot.

Our pond stays running year round. But, the water temperature sometimes drops below 45f. We use the cold weather bacteria blocks to bolster the water quality. This video is in Ontario, Canada a week before Christmas and the water parameters are so good the koi are even getting a small meal.
