These DO work! Review by Sue

The water out at our barn has a very high iron content and looks cloudy within hours of filling the horse's tank. The algae thrives in it. I've tried several water treatment methods, but Stock Tank Defense works the best so far and it is super easy to use. Just toss in a tablet after you've cleaned the water tank. It keeps the water in our 100 gallon tank clear for at least two weeks. When in gets cloudy, I toss in another tab, and it clears the water up with no problem for another two weeks. I completely power wash the tank only once a month now instead of every week. That's great!
The horses don't seem to notice any bad taste like one of the liquid treatments we tried. They refused to drink the water with that one. My horses and I give Stock Tank Defense a big five stars.

These work! Review by Melissa

I had been getting these locally, but when my tack store stopped carrying them I switched to some of the other methods like barley to keep my tank clean. Well the barley is terrible!

After a summer of struggling I looked online and found the bags here! Great price and even cheaper then what I was buying it for locally as long as I get 2 or more bags. Still works great. I have clean tanks with no scrubbing. I'm so happy to have them again.
