Actually it's very inexpensive.
All you have to do is buy two pure silver dollars, drill a hole and hang them into the water on a non conductive rod then charge them with a 9 volt battery. Two silver dollars will make tens of thousands of gallons of colloidal silver.
Once you buy the coins. The cost is merely water and a 9 volt battery every three months. 😊
It's much cheaper than buying fungicides.
