My small koi pond was full of algae due to direct sunlight for more than 10 hours a day. Despite 2 UV lamps algae still cover 70% of the sides and base. 2 weeks after applying Pondworx the base and sides began to clear up to 40% and the aeration pumps also became more vigorous! Bought second bottle already!

My garden has a very large natural pond which unfortunately had a problem with biofilm. I used the full container of PondWorx Pond Bacteria and the following day the pond was much improved; a couple of days on and the pond has greatly improved and the water is clear. I can actually see the fish again, which by the way are unharmed. I would definitely recommend and will continue to use periodically or should the pond have another problem with biofilm. Depending on the size of your pond it could become expensive, however this works.

This bacteria works great. I start using it in the spring and before long, maybe a couple of months all the sludge in the bottom of the pond is just gone. If you want to accelerate the process, I noticed if you add an air hose to the area it works even faster

I've tried other bacteria in my pond and this one actually worked. My pond is 1.25 acres by 5 feet average, and one bucket cleared it up in about 4 weeks. I can walk in it without being overcome by sludge :) yay!

Pros: This really works on clearing my 1/3 acre pond. It went from brownish water to crystal clear in about two weeks. No negative impact on the pond in any way. I used a full jug since the pond is about 13 ft at the deepest and averages 6 ft. Cons: The water will start to revert back if you don’t apply again every 2 months.
