Simple pond filter system with very good effect

Construction (chamber system with UV lamp):
The instructions in my opinion is partly misleading. You always have the feeling that anything is missing, as shown in the instructions dismantled some components (eg pump), although they are already assembled.
With logical understanding and healthy sense of proportion but one tends after a certain time anyway to no guidance the knap 20 parts assemble together.

Installation:
Very easy. , Chamber system put pump into the water on the ground floor next to the pond. There are 2xSchukoanschlüsse required (pump + UV lamp). But I still had to get a longer hose, so I filter also "hide" can. (3m from the pump to filter are sometimes too short)

Effect:
My pond holds about 3,5m³ (approx 1.7m deep) and includes 10 wühlfreudige Golfische (20-25cm). I have virtually taken over the pond unkempt.
Many suspended colored water scharz-brown. A water lily came in, because deposited on the leaves of these substances. The goldfish were just to see if they are attracted to the surface.

When you turn on the device you can see the difference immediately to the water, which is located in Tecih and the water that comes out of the filter.
After a week you could already see deep about 15 cm. The fish hold increasingly on the water inflow.
After 2 weeks, no noticeable change - ie filter times cleaned. That was absolutely necessary.
After 3 weeks, the water turned from black-brown toward green. But no problem, because the selling agency for this is indeed a UV lamp integriert.Ich could now see loose 25cm deep and the stones of the 1st Vergetationsstufe.
After 4 weeks, the water was still green (strong sunlight), but I changed again the filter.
After 5Wochen the water was so clear that every stone and every Tecihfoliefalte could see on the 1st Veg.-level (ca.30cm), but I now saw the stones of 2. Veg. level - ie visual depth and 60cm loose finally fish without that they have to be lured.

Next I will not "clarify". The pump remains on Veg-level 2, so the fish do not have a level to protect and hide.

The system can certainly circulate even larger ponds and filters, but my Tecih had been for many years has not been maintained. After initial skepticism, because they hoped the process of clarification of water is faster am now completely convinced of this product and recommend it for purchase.
