I was wondering if anyone uses these?
I'm interested in getting some, but I'm not sure what size to get. They are designed to attach onto canister filters, but I can't find any sort of guide that will tell you which size fits on what brands of filters.
I use fluval filters for my aquatic tanks. I have the Fluval 105, 405 and FX5. I was wondering what diameter of heater I'm supposed to get for these models.
They have two models of heaters, the "200" that is either a 1/2" hose or a 5/8" hose or a "300" that has a 5/8" hose.
I think I need the 5/8" hose for the 105 and 405, but I'm not sure if the hose for the FX5 is too big?

Also, am I supposed to change the tubing on the Fluval Filters to clear smooth tubing instead of the black bumpy Fluval tubing that it comes with?
