Would using swamp cooler runoff to fill a pond be safe for wildlife?
So I have a swamp cooler (evaporative cooler) with a minor defect that leaves the water constantly trying to fill instead of only filling when the level drops too low. It's untreated well water, and it doesn't have anything added to it from running through the cooler. It just flows over some mesh mats then pools at the bottom of the water pan.
I just set up a hose and rain barrel under the cooler to catch the excess water and have it run downhill instead of pooling on the dirt and creating a swamp by my house, but im thinking I could maybe have the hose feed into a pond shell my grandma never used and make a little pond for the local frogs and birds instead.
Before I do that I wanna be sure there isn't something about this setup that would end up poisoning the local critters that swim or drink in it.
