I was going to purchase a Fluval Spray Assembly for my Fluval 106, but there are 2 sizes 12mm version and 14MM. wondering which one will fit? BTW I'm still using the original tubing. let me know if you have the answer, thanks
i think the hose sizes changed from the x05 to the x06 series. i remember somebody linked to a great chart on either this forum or aquariumforum.com... was quite helpful but didn't come up in my own google search. try doing a forum search, it's in there somewhere!
