14000 have now turned on three weeks day and night to Biosmart. At the beginning of the same in given Bio Quick Starter. At first the water was cloudier than a few days before the filter insert. Now it's in untieferen part with about 80 cm deep crystal clear to the bottom. The UV lamp I have so far not yet been switched on, since one because of the structure of the micro-organisms should therefore wait in the filter sponge. The sponges can be cleaned easily, although it is somewhat cumbersome to collect the waste water front, since the drain tube (purchased separately to) about 40 cm above the water. The 3/4 inch tubing between the pump and filter might be a bit longer, but I have bought an extra oasis hose so that the water in the pond can cirkulieren well. I submit a clear recommendation for this filter set! Would buy again.
