CrystalClear Barley Extract Pond Treatment – Natural Water Clarifier for Fountains, Water Gardens & Koi Ponds, Clears Cloudiness, Fish & Plant Safe, 2.5 Gallon

This stuff is incredible! I take care of two ponds that total 1.5 million gallons of industrial processed water. This will not only improve clarity in a matter of hours, but it will also breakdown oily biofilm deposits. It’s very safe to use without gloves - but still be mindful not to spill. I’ve had this product shipped several times, and not one of them has arrived damaged or leaking.

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.

It works almost as soonas it's poured in the water. I had algae build up on the sides of my water feature. Within the hour the algae started to go away.

This pond treatment works for our large fountain. I don't like using anything with chemicals because the birds drink from the fountain, so this is the perfect solution for keeping the water clean and free from algae. And the price is right!

Worked great for our pond. We also bought the floating straw and it was crystal clear in about a day.

Do not believe what you read! If you dig very deep and click just the right link you will find a disclaimer. My pond is less than a month old. I used exactly how directed & ended up with a cloudy pond. Brand new Crystal Clear to murky water in less than 30 days. "Maintains Clean & Clear Water -- CrystalClear Barley Extract is a powerful liquid concentrate that works with nature, providing a year-round solution to maintaining a clear koi pond or water garden." "....maintain beautiful, crystal-clear water." The above are quotes from their advertising that I found to not be correct for my pond. I have used Barley straw in the past successful & thought I would try this because it would be cleaner and easier to work with. What an EXPENSIVE MISTAKE!

It works well. Will buy again.

Just recently used this. It has killed all the beautiful moss in the several waterfalls in my water feature. It must be stronger than the Microbe-Lift barley grass I usually use. That’s why I only gave 3 stars. Think I will stay with algaway and regular barley grass…..must say the micro-lift barley grass is weaker.
