MICROBE-LIFTMicrobe-Lift Concentrated Barley Straw Extract Conditioner for Ponds – 1 Gallon – Safe for Koi Fish, Plants & Decorations – Natural Pond Conditioner, Cost-Efficient & Organic Solution

Works wonderfully, BUT you have to keep up on and with it, it only works if you do your part in adding it as directed! Good stuff! It is all I use, and it keeps the Algie away, again, used as directed!

Great price for great product

It works

Ideal product for small water features.

Works well if you keep to the schedule. Does a good job maintaining a clear pond. If you have to clear one up would recommend other methods because this will take a long time

I had tried this product a few years ago but wasn't very impressed. Not sure what made me buy it again but I'm glad I did. I suspect the first time I did not treat it weekly, because it has done a fantastic job on preventing algae. Followed the directions this time for the past 3 weeks. It cleared up the pond water within a week and has kept it clear of algae despite 2+ weeks of 90°+ temperatures.

I love using this product on my pond since it does work and affordable. Koi approve.

I use this throughout the summer to control string algae in my Koi pond - it does a great job without harming either the fish or the numerous tadpoles in the pond.
