Thanks! The water doesn't stay clean for long. However, they are Muscovies and don't spend as much time in the pool as Mallard-type ducks would. Using the water in the compost is a great idea! My duck pen surrounds our small orchard and right now the pool waters the fruit trees.Very nice! Those ducks look quite happy. Love the sink drain idea for draining the pool.
How long does the water stay clean? I had ducks and geese years ago, but they made a mess out of everything fast. I don't think I've ever seen duck pool water that clean!
Just a thought, but I think that duck pool water would be great on a compost pile when you drain it. Save all that duck manure in the water to supercharge your compost. Looks like your pallet wood deck duck pond is built on a downhill slant, maybe you could put a garden hose on the sink drain and gravity drain all that water into a compost bin(s) somewhere downhill.
