great for pond fountain

by
built my own pond fountain using one of these. wish it came with a longer cord, (50 ft. would be better) but added 25 more feet to make it work for my pond. use it about 8 hours each day with a timer. electric cost is neglible. keeps mosquito population down (breed on stagnant water) and distributes chemicals evenly. have less algae also. In northern climate and used from April throuigh October. In fourth year now (2017) and still works great. Remove it in Oct. each year.
