Hi! I have a 700 gallon raised pond built from 4x4 timbers. On the one end I have the spillway which comes from a Zakki shower filter and pre-filtered by an Oase 3000 pressure filter. The Oase and other equipment are kept in the filter house on the end as seen in the pictures. I've seen these autofill devices such as this one from Sacramento Koi https://sacramentokoi.com/external-auto-fill/ but not sure how I would incorporate it with my setup. Or maybe a DIY one with this: https://www.amazon.ca/Little-Giant-5...7325224&sr=8-2 I'd be willing to cut through the 4x4s and the pond liner to install a pipe going to the pond from one. I'd prefer having something as hidden as possible and not taking up real estate inside the pond. Also not sure but I'm guessing I'd have to disconnect it for the winter time to avoid the water feed hose from freezing--or maybe I can get it insulated somehow or use a pipe heating cable or inline heater? Any ideas?? Thanks!
