We are in need of advice from the experienced koi lovers here.


This is our new pond. I do think the filtration is not enough. Currently we are using Laguna without UV light. I have a friend who actually advised us to add another chamber consisting of all sorts of matters to filter the water instead of using the Laguna . I have tested it with local cheap koi as well as tiny swordtail fish. But the water is still green and murky with food matters floating. What would you advise us to do ? I want to be sure before I proceed.

1. Can I keep the Laguna and make improvements and yet have clear water if I rear 9 kois?
2. If I were to add a chamber, what about the pump and piping on the floor of the pond? Will One piping with punctured holes be sufficient ? Do I need to create a gradient on the floor of the pond so waste matters would flow to the piping system to be pulled out to the filter ?
