Summit Clear-Water Barley Straw Pond Treatment, 2-Pack, Treats upto 2000 Gallons, 1000 Gallons per Bale

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.

Works well to keep algae down.

Have a very small pond maybe 200 gallons, it filled by my ground water sump and I'll also have a hose dripping, the pond is water source for my honey bees. Bees love it but I've always had pond scum and algae issues, we put minnows in to eat the mosquito larva and gnats. Pond was noticeably clearer after 3 days, but bale sunk, so I rigged up rope to keep it near aerator bubbles and I can swap bales out with ease without have to go all the around house (I have a handicap and walking can be a challenge) would of been 5 star rating but sinking after 3 days, and directions say if it sinks you need to remove and let it dry out, so I'll rotate them when one sinks replace it with the dry one. 1st picture is after aerators were installed next 2 are after 4 days with the barley bale was placed in pond.

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 don't know if we did not give it enough time, but this did not work for our pond. We still had a lot of green murky water even after three weeks in the water. PS We placed it in the pond tank right after cleaning and two days later the water was dirty again.

Works well in ponds

I believe that this item has been stored incorrectly or is extremely old from years in storage. It does not work in the slightest. It simply floats around and even accumulates algae itself. Please refer to other recent reviews and you will see that this is a pattern.

Worked like a charm fir clearing the algea in my very small pond.

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
