Tetra Tec1200

Hi, i have a Juwel Filter running with my 190 Litre Tank, it looks after itself and is easy to clean. However, i also have a tetra Tec 1200 and have noticed that the tubes runnign in and out are looking a bit green. Is there a method for cleaning these.?

there is but TBH leave it.
in the tube willbe living bacteria aiding your filtration,
they should only be cleaned when the flow is significantly reduced
