Have a Fish pond , approximately 1000 gallons. It has a waterfall and is deep enough for fish to reproduce. Algae Fix helps keep the algae from forming. This product is especially nice because it works great ,and does not hurt the live fish., it is easy to use, been using it for years, definitely recommend it.

Followed directions and actually used way less than recommend for the size of my pond to play it safe. It killed all 9 of my goldfish in two days even though my pond has a air gathering fountain spray. My suggestion.........Remove your fish if you don't want to kill them before using.

Have not used it yet the weather is not warm enough. I use this product many times works great. I use it when the weather stays above 40 degrees at night. to kill any algae growth that has started during the winter.. Along with the UV light have no problem with algae during the warmer months Just make sure you have your pumps up and running before use it will lower the oxygen level in the water and could hurt your fish..
