So we know the general idea is to keep as much equipment out of view right? After all no one wants to look at equipment that doesn't have to be in the tank. Same goes for diffusers and this is why the Neutro Inline Glass Diffuser is so great.
Made with laboratory glass, this inline diffuser comes in 2 sizes - 12mm and 16mm. I recommend placing these diffusers on the outlet pipes - some place them on the inlets for better diffusion but you end up cleaning them more.
To attach it to your tubing, warm it up with a hair drier and it slips on nice and easy. Similarly when it comes to cleaning them (and removal) get a hair drier on it again which makes the tubing easy to remove.
