2000G pond and 830G sump (almost)

[Yanbbrox]

This was when I first fired up my K1 fluid bed, media is brand new and perfectly white with no bio added, fish were slowly added after this and if I can find the picture I'll post it.

This was running only about 30 litres of media at the time, this has been increased to about 105 as the bio load increased, the chamber is about 500 litres/about 130ish USG

Normally I say things, like I'll dig up a pic etc. and it'll take me an hour to find them I guess I got lucky tonight:

New K1 fired up:

Much more media added as the stocks increased, notice the brown coloring, BB building up:


I'd like to add, check out MRul07's rock filter it's great and I want one

You could go many different ways with a koi pond, there are beads and Cls that are worth a look as well

Good luck with the project
