we have a natural unlined pond 20ft x 40ft by 2 ft deep and has begun to have string algae we need a product safe for water as it is unlined - can you give me info on if your product will work and how much to use...and how often - we are in Colorado
GreenClean Pro Algaecide is safe to use in your unlined pond. You would want to use 1-3 tsp per 1000 gallons water. Your pond appears to have approx. 12000 gallons of water. So, you would use approz. 24 tsp to treat your pond.
