Barley Straw for Fish Ponds and Fountain (16 Oz). Treats up to 3000 to 5000 Gallons, 100% Safe & Natural Pond Cleaner. Keeps Your Water Garden Clean & Fresh. Made in USA

There is a neglected pond near me. There is an inlet but since we're in a severe drought, there hasn't been any water flow. It is always algae covered in the summer and very gross. This is not the type of pond recommended for this product. Since the pond is not in a place I can actively manage I took the straw out of the netting and tossed the straw flakes (sections) in. They floated on top and are still floating on top. The areas around the straw are already improving! It has been 4 days. This is a large pond and I know I can't treat the whole thing but deer frequent the area and I was hoping to clear the water for them. I didn't want to leave the netting unattended not knowing what to expect from the product and being concerned for the turtles. I cannot believe the algae is already dissipating!

I learned about barley hay and algae many years ago, and now this is all I do to keep it under control in my goldfish ponds (4000 gallon). It’s natural, and chemical free. Packaged as they are, it is soooo much easier than buying an entire bale, and breaking it up to use which is super messy. I am sold on these, and would recommend them 100%.

Most of the barley I have purchased are these little tiny things. This is big! It is a great size for a pond. Best yet!

It worked real slow, but take your time about 3 weeks.Makes a difference.

This didn't work in my pond. The bale was very large and bound with loosely woven net. It was loosely packed and absorbed water. Due to weight it sank quickly (within days). Also the netting weave was very wide so pieces of straw slipped out and there were bits floating around on the surface. I have gone back to a product which floats longer and has a tightly woven fine netting that contains the straw (and also seems to have less absorbency).

Before I put this in the lily pond, there was no green algae, but I like to KEEP it clear, and barley straw normally does a great job at that. I usually use a different brand than this, but decided to try this one for a change... I can't be 100% certain, but apparently that was a mistake on my part.All I really know for sure is that a day after I placed this in my pond, the water began to turn green. There have been no other additions/changes to the pond since I placed the water lilies in there over a week ago, and there was no algae in all of that time.The sudden appearance of the algae really caused me a lot of extra work, (filtering and changing out the water in the pond), I otherwise did not need to do.So, as I said, I'm not really sure what the heck happened, but just in case, I'm sorry but I won't be using this brand again and shall go back to buying my old and trusted brand.

This is awesome! We will be buying several now to be able to swap out every few days. It cleared up our green pond after the algae fix killed 4 of our koi, left us with 3. We didn’t want to use anything chemically related at all again after that. Algaefix apparently kills fish a lot!! Someone mentioned this straw, we found this and tried it. Took 2 days to clear up a 3000 gallon pond. We bought 2 smaller ones we toss in when we pull out the bale. Rinse out the bale and let it dry. Then a few days later we pull the 2 small ones and drop the bale back in, rinse the 2 small ones and let dry. Works great. Will be even better when we have several bales to swap out every few days.

Straw came out of bag, clogged filters badly. Never had that happen with other brands
