CrystalClear Barley Extract Pond Treatment, Water Clarifier, 1 Gallon | Natural for Fountains, Water Gardens & Koi Ponds, clears cloudiness and is Fish & Plant Safe

Works great! Water was completely green. Took about 4 days to get crystal clear water again. Would definitely recommend

Excellent product for clearing pond algae, much better than the barley straw. Just be aware of instructions to add adequate aeration if applying to a heavily infested pond. The breaking down of the algae causes oxygen depletion in the water. I thought that I had adequate aeration and lost some fish, will not make that mistake again. Have used the product to maintain a clear pond since my misadventure.

Used according to instructions. Small two level water feature with circulation. You need to be patient. It did work finally. Cleared water feature after but used the entire bottle in. Within two days water cleared.

this is the stuff to buy. it works. seems to eat up the crud on the bottom of the pond and sends it to the top where I scoop it off. better price than all the other stuff I've tried too.

Use it in bird bath. Takes a few drops and keeps green algae at bay.

Applied as instructed to two water features that have green algae. I had already cleaned the water features. Helped a little. Increased both dosage and frequency of application. Worked a little better. Finally alternated between barley extract and Algaefix. Worked a little better. So now I just alternate the two more frequently than instructed. This is the only brand of barley extract that I've tried, so I can't say if another brand would work better.

This does not work at all. I increased the amount --I have a small 8 gallon pool for geese to splash around in ---and it only takes 24 hours for algae to develop.

Essential product for keeping the algae down in my small pond. While it did not completely remove all the algae, it does control it. My pond receives a lot of sun so the best I can do is manage it and so far this product has been essential in helping do so. I do not need to use a lot but I use it every 2 weeks and I do notice the algae dying and minimizing reproduction. I am very happy with the product.
