Here's my raised,long concrete pond, just built, painted with a pond sealent and has 8 goldfish in it just to start with.
I'm wondering what sort of pump and filtration i'd need on such a long shaped pond?
It's about 5m long, 1.7 wide and about 60cm deep. I plan on having some lily pads, a big fresh water fish of some sort and maybe a small water fall up one end over rocks. No fountain..and most of the pumps i can get are for fountains.
I just don't want to change the water often and im wondering how good the water will circulate but will a to strough a pump blow the water out?
Anyone have a pond like this?
