Is it safe to put in horses water trough
Answer by ChewyJul 06, 2018
Barley straw is non-toxic and safe for use in drinking water.

We have a 50, 000 gallon pond will these work in it?
Answer by ChewyMay 09, 2020
1 package of 2 bales treats up to 2,000 gallons. This can be used in your pond, however, you may need a few more.

How much piece I need for a 110 gallon tank deep
Answer by ChewyJan 25, 2018
Each mini bale treats up to 1,000 gallons of water for up to 6 months. Allow about 1 month for the bale to reach full effectiveness.

Does this clear dirty water up, say, had clay or dirt get washed into it?
Answer by ChewyJun 21, 2021
As it slowly decays, byproducts are released that aid in maintaining water clarity, which are harmless to fish and other plants in the pond. Barley straw may be used at any time, but best results have been reported when starting in early spring when the water temperature is low. Bales should remain floating for maximum exposure to sunlight and oxygen, which aids in the decomposition process and accelerates the pond clearing benefits.

Barley straw

Hasn't worked yet. Got these in early April to add to our goldfish outdoor pond. We clean the pond in the early spring and wanted to try something natural to control algae. We have goldfish, plants, waterfall and aerator pump. It is less that 200 gallons. The barley was placed under the waterfall a month before warm weather. It did not control algae. It actually had algae growing on it as well as some barley sprouts. We periodically sat it in the sun to dry, but eventually had to resort to the algae fix liquid.

I love these!

I have spend almost 2 years fighting with my Koi/Golfish pond being too murky. I have used numerous "natural" additives that have never really worked. I put one of these straw bundles in on April 8 and today is April 27. I didn't notice any difference until today ( the package says to give it a month to begin working). I wish I would've taken a before photo, but trust me when I saw that you couldn't even see the fish unless they were right at the surface. I see a huge improvement already and it hasn't even been a month yet. I had to get at a weird angle to take the photo because of reflections, but you can see my fish several inches underwater towards the top of the photo. I'm impressed already and can't wait to see if it continues to improve in another month. For reference, my pond is odd shaped but is approx. 3x8 and differes from 1-3.5 feet deep in places, and I used one bale. I bought the 2 pack so that I could double them up if I needed to but I'm going to wait and see how this one does and maybe have the other on hand for next year. I did have it sink once,after 2 weeks, but I scooped it out let it dry in the sun and placed it back in the next day

Algae problem disappearing

Excellent service from Chewy!! Product as described and noticed pond is clearing up daily. Would advise to tie them with string as they do sink and have to be dried out. Otherwise great product.

Clearing well

I have a couple of 350gallon tanks with fish and have begun using one bale in each. After a week or so the difference is dramatic. I can see the bottom.

I like the idea of natural cleaning process for my pond that are chemical free and safe for all the critters that call my pond home. But this product does now work. The directions say place barley straw bundle gently on the ponds surface and let it float around and if for some reason it sinks to take it out place in a dry spot so it can completely dry and then place back in the pond. It also states that the product will not work properly is it is completely submerged. So I followed the directions. I do have a fountain but I separated the pond in half with a pool noodle so that the fountain would not affect the bundle. But the bundle keeps sinking even though it is calm water it sinks. The first time I was like" ok maybe it was the wind" so I took it out and dried it in the sun and placed it back in the pond. Next day it was setting at the bottom of the pond. I did this for 3 weeks until I just gave up. My pond is under a gazebo and if is safe from rain so I know the rain did not drench it and cause it to sink especially since it only rained once in the weeks I tried to use it. I really love the idea of this product and I am sure it works great but maybe the manufacture should attach a small Styrofoam float to either end of the bundle to keep it above the water. I am going to do this with my other bundle and see how that works.

Completely Pleased

I was grateful for it's availability. I had been trying to get it from my regular supplier for a long time. I was impressed by the size. It was much larger than I had previously used. I use it in a large tire water tank for livestock. For some reason this tank has a reoccurring moss problem. I think it will do a good job. But it is a little to quick to confirm.

Great product

My barrel pond was very murky and this product cleaned it up in a few days. I did arrange a plastic bag around the bar so I could remove the scummy stuff as it spread easily if you moved easily back into the water when I moved the bar. So glad I found something that works. My fish are happy too.
