In line heater

[Dave55]

Hi guys,
I have purchased an in line heater. I then realized the tubes on my 107 filter are ribbed so i have been told they will not work!
Can anyone tell me if there is a mod or if i was to change the tubes, what diameter tubes do i need for a good tight fit?

We don’t know what size your existing tubes are or the size of the in-line heater you got. If you don’t know, maybe if you tell the brands/models someone might happen to have the same thing and be able to advise.
