Excellent product to keep water in your fountain clean!
I use this product to keep my water fountain in the patio clean. Especially in hot weather in Arizona, during the summer you need to put a capful or more in the water at least once a week. I have been using this product for over 15 years and found ordering it on Amazon was the best price and fast delivery. Very happy I found it here and you will be too.

best for fountains
We've used this in our 3 tier fountain -- keeps it sparkling and is ok for occasional bird to dip into water.

Best product for greenhouse pathogen control
I've been using this product for many years to control pathogens in several greenhouses. I don't know of any other product that effectively controls such a wide spectrum of fungi, bacteria, algae, etc. It is so concentrated that when appropriately diluted with water, a gallon jug will provide multiple years'-worth of spray and drench applications.

Love it!
I use this product in my greenhouse weekly. Its hugely effective in controlling algae that can build up on the floor and be very slippery. Love it!!
