1. Back in May this year, I decided to scrap my home made filteration system and purchase a Nexus 200 Eazy. I got a very good deal locally and installed it the same month. This is my experience with the nexus so far... 
2. I use a Nexus 300 + an Easy, I drilled out the holes in the Nexus Air-ring to 2m, fitted an Hi-Blo 80, and I have crystal clear water, and no problems, only Blanket weed which cloverleaf B/W is removing.
This website started with a booklet which I made up originally for the help of those members of the BKKS - South Wales Section who were intending to start building a koi pond, and as the website has expanded more information and articles from other people have been included. This is for general guidance only, and we do not take any responsibility for problems that might occur by following these ideas. It is important that you check out everything in your area, and check on local laws and rules that may apply.
