Sorry about the typo, its actually about 3000 ltrs.
Water quality is improved since using a stone/media bio filter for a few days. I dont need to clean sludge off any more, so feel im on the right track
Planning on just under 11000 ltrs for the new pond.
Im hoping to use the existing pond as a kind of bog pond with a small stream feeding into the new one, with catch pool to a skimmer run off.
Might take a while, but it's captured my attention from the rat race grind
