Hi everyone! This is my first forum post outside of my intro and responding to an existing thread so if I should do anything differently, let me know. My question is, does anyone have recommendations to fully or partially automate keeping a duck pond clean? What I'm hoping for is to find out about specific brands and models of filters (bio filters?) and pumps to look for and ideally ideas based on others' experiences. For reference to know what we're working with, here's a photo of our duck house for our two girls. The main structure is about 8' by 10' and the attached enclosed pond area is roughly 6' by 4'. The pond itself is a Rubbermaid 50-gallon stock tank that we buried with maybe 6" above ground. We have sort of small river rock surrounding the pond. Our current practice is to place a pump in the pond each evening to pump water up and out over our yard; we have a very long, wide hose attached to the pump to avoid creating small marshes. It's not difficult but it's getting tedious, and I'm not looking forward to having to keep this up through the wet, cold winter here in NW Oregon. We thought we'd have come up with a solution by now but as first-time duck keepers on a budget, it's been really hard to want to spend a couple or few hundred dollars to figure out what's best. Thank you in advance!
