CrystalClear Barley Extract Liquid 2.5 gal

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.

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.

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.

Its a great product and works within days. Delivery could have been better as the top of the container was off but the seel didn't come off.

I have been ordering this product for several years now. Since I've been using it in our pond is noticeably clearer and cleaner. I will continue to order this product as needed.
