Our pond has been doing fine for about 1 year, 3 coi, 4 gold fish and
several frogs moved in so we now have about 300 tadpoles. But, we are
finally getting around to getting a water softner system. They work by
addind salt to the water, so when I add water to bring the pond level
back up, do I need to worry about salinity? Pond is about 1400 gallons
and the level drops about an inch every couple of weeks.
