FZONE ATO tube size

[rjp83]

Hi all. Does anyone use the fzone smart ATO system and happen to know the diameter of the water tube? I need to make a new longer run from the chamber to my new 75g. I believe it’s 7mm ID but just want to confirm ID and OD.
TIA

The Fzone tubing fit my hydros water pump which is 6.5mm ID.

To be sure, put the part of the pump where the tubing connects between 2 parallel flat surfaces, measure the distance between them. Assuming you don't have calipers that is.

Mine came out to 7. Bought some 7mm Id tube and it worked perfect. I bet I could have used the 6.5 as well. Thank you for the input
