Quick question. I have an Oase Biomaster 250 thermal and recently picked up some glas lily pipes from FZONE really cheap! Problem is I made a mistake and ordered 12mm lily pipes and as you all know the tubing on the filter is 16mm. Would it be detrimental or damaging to reduce the tubing down to 12mm with some reducers? FYI the filter is going on a small 60 liter tank so is substantial overkill!

From what I remember, the standard outflow that comes with the filter has a register to reduce flow, so I'm sure reducing it isn't damaging.
My experience is that the biomaster 350 doesn't react well to restriction in the inflow, the reduced inner pressure helps eventual leaks of air into the filter, and the annoying bubble sounds. It becomes evident when the inflow gets blocked by detritus or something like that. If you come to experience excessive noise due to air entering the system, I would advise to try to replace the inlet. But not without testing it first.

I used a 250 with 12/16 reducers for years. Never caused any issue.

You can always get 12/16 pipe , cut 2 inch piece and slip it over the lilly pipe and then 16/22 pipe will go over that .that's what I do , I think I have seen George farmer do this .

I have the 12mm lily pipes on my 60P as they look more in proportion for my tank. I have not noticed any significant reduction with this, when using my Biomaster 250 thermal, or my Biomoster 250/350 hybrid thermal (a 250, running a 350 head). If you feel that you need extra flow, you can always change the pre-filter sponge (I think to orange), and the other option is reducing / removing some of your media in the 250.
That is an In-line Co2 diffuser!
excellent many thanks 🙏
