pond-filter upgrade

biofilter1

biofilter2

Since my 4 Goldfish decided to multiply several times this summer my biological trickle filter (made in 2012) ended up being much too small in volume and too hard to clean. So here’s the new one with 4 cutlery drainers stacked containing various biological filter materials (lava stones, perlite, ceramic tubes and Zeolite at the bottom), housed in a flowerpot and exit with a shower drain. All still working with the original solar pump system. Still working on a lid (instead of the splash hood from the kitchen).
