Pond In and I'm a Happy Bunny

We have installed the pond and the new filter system created specially for us by Cougar Coatings Waste Water Division. After much deliberation and heartache we found this company and they responded to my plea to let us have a solution to our duck pond.   They normally deal with industrial sized sewage plants but were very happy to answer any questions- however lame - I had about how to solve my problem. Now ducks are very messy creatures, they can turn perfectly clean fresh water into chocolate coloured muck in the space of 10 minutes. Its not their fault, its just that they dig in the soil and then they have to rinse their beaks and sinuses out and consequently all this muck ends up in the water.  They shake their beaks in the water and this flicks all around the water containers and turns the surrounds into a mud bath. Great for ducks, bad for chickens. Our pond was first installed with an Oase filtral 5000, a filter/pump which comes with a clear water guarantee. Doesnt work for ducks, nice clean koi yes maybe, but ducks, definitely no. Our pond is 470 litres and this pump is capable of 5000 litres per hour. Complete rubbish. We then purchased another external filter to filter the filter. Another complete waste of money. The filters were gummed up with feathers and duck grease in a week. Dirty water continued. Most of these fancy filter systems are all designed for Koi and Koi bear no resemblance to the problems caused by ducks. We have installed our new "mini" sewage treatment plant designed by Cougar utilising a Bio-Blok and nothing more exotic than an air pump and our dirty pond is clearing in 9 days. We can nearly see to the bottom of the pond, despite the ducks dabbling in it for the whole 9 days. We added a UVC to the outflow to kill the microbes and nasties that might still exist and hey presto. Healthy water and we haven't had to clean a stinking filter out yet.  If you have a pond problem and need a brilliant filter, you wont go far wrong by speaking to Cougar.  I have to say to Andy Gostling and Dave Ward at Cougar, that you are my heroes. A huge thank you.
