## Overview

CrystalClear Barley Extract Liquid is a natural, eco-friendly pond treatment that safely reduces debris and maintains crystal-clear water. Each 2.5-gallon container treats up to 20,000 gallons for 4 months, offering a faster, cleaner, and mess-free alternative to pellets and bales.

## Description

As barley straw slowly ferments or rots, it produces a natural extract that has been proven to work as a powerful treatment to clarify pond water. While effective, this fermentation process has always been slow and messy requiring the barley to be added early in the spring. Designed to eliminate these steps, CrystalClear Barley Extract was fermented under ideal conditions capturing the powerful all-natural barley extract, allowing it to work immediately out of the bottle, with no mess. It's the natural solution to maintaining a clean and healthy pond all year long. Faster than barley pellets and cleaner than cumbersome bales, CrystalClear Barley Extract is a powerful liquid concentrate that goes to work fast. With CrystalClear Barley Extract, you can enjoy the benefits of barley straw treatments without the mess and without the wait. Apply 1 ounce per 500 gallons of pond water once every two weeks.

Review: Liquid GOLD - 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.
Review: Please understand this will NOT KILL ALGAE - Like the title says, this product is NOT designed to KILL algae. If you want to KILL existing algae you will need a proper algicide. String or mat algae will form when organic materials are allowed to decay in your pond. In my situation we did not get the pond cleaned out in the fall, so once spring hit and the sun came out the algae started to form. We were only using beneficial bacteria and blue pond dye last year, however the combination of these two products prevented mat algae from forming. We now have fish in the pond, so we discontinued use of the blue dye so we could see the fish better. With more sun hitting the pond (which has virtually no shade at the moment), the algae reared its ugly head. Again, since we have fish I did not want to put a chemical in the pond. This is why I chose this product. This product is designed to prohibit the growth of algae, but it will not kill what is already in the pond. If you have algae now you will need to clean/scoop/drain the pond to get rid of what algae is there, then add this product. We have a 16,000ish gallon pond with a natural bog filtration system. We did not drain the pond this spring, rather we used a vacuum to suck out the existing algae and leaves. I then applied 1/2 a gallon of the barley extract along with the proper amount of beneficial bacteria. Using this product GREATLY DECREASED the growth of algae, which is exactly what it is supposed to do. The thing is, you have to use this product WITH your beneficial bacteria EVERY WEEK until you have the issue managed at a level you are happy with. Using a natural product like this helps balance a natural ecosystem by allowing the proper things to thrive in moderation. If this is not something you are willing to tackle, then you might want to consider the chemical route or a UV light system. If your pond is in the open sun like ours, it will be much more difficult for you to control the algae. Plants in and around the pond, shade trees, sun netting, pond dye will all help prevent the bloom of algae, but you will need a combination of things to keep your pond looking decent.

### ⭐⭐⭐⭐ Worked for a while on pond with heavy debri
*by O***K on 7 June 2024*

Purchased 2.5 gallons. Poured 1/2 and a couple weeks later the other half. I think it was definitely clearer. But didn’t last and we will have to continue to treat. To be fair, our pond is in the woods and has heavy debri. the oak leaves among others have coated the bottom of the pond along with some plant life that we don’t want in there. The water comes from a spring so there’s no filter system it just continually fills and has a run off. We do have a lot of ducks as well which stir up the water. This didn’t hurt the ducks or turtle that’s in there. The pond is about the size of a football field and red clay dirt if that help. I will purchase again and see if another round improves clarity.
