Summit...responsible solutions Summit 125 Clear-Water Barley Straw Bales, 2-Pack Treats up to 1000-Gallon

Works well in my backyard pond. My pond is only 100 gal., so one of these is sort of 'overkill' for it, but it works well to clear the water, and I'll keep using it. After a couple of weeks, it sunk to the bottom, but it was easy to fish out with a net, so it's currently drying out, and I'll put it back in soon. It's nice to be able to see the fish again!

I have been using these for years now to keep the water in my pond and waterfall clear. I wedge it down with a rock and it slowly decomposes over the season. It is very effective and no longer need any chemicals or other treatment to keep the water clear.

I have a new Pond setup. I have 125 gallon pond and have read that barley straw is really great for deterring algae. I have had this in my pond since the setup so I can't say how great it works but I'm sure it is doing the job. I live in El Paso Texas where we get nothing but direct sun and my pond is in full sun half of the day. So algae is a concern and it still happens but I do believe that this is helping. It does get water logged after about a week. I just take it out let it dry a little and then put it back in

This stuff is amazing! I was VERY skeptical that a hay bale would clear up my emerald green Koi pond, but dang if it didn't! One review said they last 3 months, and after about 3 weeks it was much clearer, but it wasn't crystal clear and it didn't seem to be improving, so I threw in another one. Now, it's crystal clear. I'm curious how long it will stay that way, but I'm ready with a new order if it starts turning green again. My only problem is, I would love to find this in bulk, but I found that the feed stores don't have barley based hay. I love having a clear pond but $10 for a few small bales when a huge bale from the feed store is $15, seems a bit high. I've included some photos. The green photo is from June 25th and the clear one is from July 17th. Booya!!! :) (Note: I put the first bale in on June 17th, but didn't take a picture until the 25th).UPDATE 5/27/2016: So, they worked the first time, but not the next. I tried them a few times and got frustrated because they weren't working. I read the instructions and it says, "put near a water fall" but I don't have a waterfall that runs 24/7. I do, however, have spitters that run all the time. So, I bought some of these http://www.amazon.com/Improved-Secured-Closure-Replacement-Guarantee/dp/B00KGEDB60?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00 and broke open a bale. Put the hay inside the wash bag and used that in my filter http://www.amazon.com/TetraPond-SF1-Submersible-Flat-Filter/dp/B0024EFYU6?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 I just replaced one of the filter pads with the was bag. This worked amazing! I just wish I could find bulk barley hay for a reasonable price!UPDATE: 8/10/2015 - So, I still love this stuff, but I've noticed it stops working after about a month. I just put in a new bale on 8/8/2015 because it was starting to cloud up again. I'm also using the barley flakes. The reviews said they work faster than the bales. I also noticed if you leave the bales in, they do disintegrate and you'll find the barley splinters in your filter and floating in the water. I'll update regarding the flakes, but will probably continue to use both.

I put it in my horses water to keep it clean, and it wasn’t tied together very well and came apart in my 125 gallon tank. A big mess! Kept water fairly clear except for barley straw floating in water.

IDK how many of these I've bought. We have a couple big tanks that catch rainwater off the shed roof as there is no running water at my raised beds. Every year I put one in each tank and they really keep the scum from stagnate water away.

It doesn’t work as advertised. I have a small pond having around 500 gallons water with algae. I tied one of those his products and threw it in the pond and it was floating for 4 days and sank inside. But it didn’t clear the algae not even an inch around the bundle. It’s a waste of money.

This stuff works. Put one bale in my waterfall and one bale tied at bottom of waterfall in my pond and we are algae free within a week. Just bought more. Apparently it can be dried out and reused which I am trying now but also glad to buy once a month if needed as well. So happy with the results.

Cela devrait purifier l'eau de mon bassin mais il faut attendre 1 mois pour voir le resultat.J'esere que cela va marcher

Very happy with the product. Smells and feels like Hay

Tengo mi estanque al aire libre y en una zona que le da el sol la mayor parte del día. Tenía tiempo batallando con las algas. Después de un mes de tener las pajas en el agua el alga disminuyó notoriamente.

To try to restrict algae in pond!

its a great and effective product
