Honestly not sure. I can check tonight. I wanna say we have 50-60 psi on our system. I'm not thinking it'll just fill the pond up over a week or anything like that. I'd be happy if running it every other night would keep up with evaporation haha. I've gotta run the hoses all the way down to water the grass. Not much more work to drop it in the pond and walk away.
Maybe also dumping in clean water would help clear it up a little?
No way to tell without knowing how much water is going in, but my guess is it'd be like whizzing in the ocean. 0 change or rather the cost of the electricity and wear/tear on the pump shutting on and off wouldn't be worth it.
For instance. my well pumps 25 gpm if I direct it all to the pond (I rigged up a 3" dia pipe going from the well to the pond). My pond, at 3' below full pool leaks 18 gpm. Is it worth it to keep pumping water into the pond AND have 0 water pressure in the house? The answer is no.
