Tubing connector for tunze 9004

[jimmypencil]

I have a tunze 9004 skimmer that I’m trying to connect to my brs co2 scrubber. The BRS has 3/8” tubing but I can’t find what size tubing the skimmer has. How do I connect these? I’m sure it’s a dumb question but this is all new to me.

The smaller tubing is from the tunze

You need an 3/16” to 3/8” barb fitting. 7 bucks on amazon, I just ordered some myself for this modification. I have two extra adapters if you want one.

isn't the hose on the Tunze 9004 1/16"? When I looked it up it said it was 1.5mm

How did you solve this?
