A gravity Fed Pump Return gULP installation

This is a three pair gULP installation that is gravity fed. The timber deck covering the filter chamber is being constructed. This was originally a swimming pool that has been converted into a Koi pond of around 60kl. It also has ducks - so we have added a bit extra to the filtration system and a higher turnover rate than normal.

The pond.

The feathered residents. Cute as hell, but messy as sin!!

The filter chamber with some neat steps going down into it to make access easy.

Bubble bead filter awaiting a prefilter. You can also see the large waste sump for waste water awaiting sump pump to pump to waste/garden irrigation.
