40ft by around 12.5...... ok my maths was out, that's around 500sq ft...... well if you're going to dig a hole may as well make it a big one eh?! The filter I'm designing myself. These are fish I've been maintaining for 30 yrs so I know what they need!! Primarily solid settlement, there'll be a separate biofilter as well. Fish wise, as I mentioned in previous messages it's going to be less of a koi pond and much more mixed community. Lots of water lilies too, some of which are almost busting out of their baskets! These will be "potted on" when the pond is ready to plant up.
