3 Evolution aqua 55w UV lights

Big filter upgrade!! For 5 years I’ve had the PCF50000 filter it’s done ok but as my koi have grown it’s taken more and more cleaning to the point yesterday I was put to my elbows in it after only a week since the last clean. I’ve just had delivered 2 kockney Koi 20,000 filter boxes quite cheap. I plan on running both, each with brushes, foam, Japanese matting and K1 media. Ps. It came with 3 Evolution aqua 55w UV lights which I don’t need, will let them go for £35 Ono each if any one is interested in Pe15, collection only. Currently untested will check them out later.
