Product Questions

Is this the same rigid tubing that comes with the BRS 1.1ml dosers?
Question by: Pete Thompson on May 31, 2017, 1:06 PM
The 1.1 mL dosers actually come with a length of standard 3/16" airline tubing and then slightly more rigid tubing which is actually provided with the pumps from the manufacturer. The closest option we have to this is the flexelene tubing at the link below.


Happy reefing!

Are there bulkheads for this size tubing like there is that fits the regular 1/4 tubing for ROI units. And also are there connection or junction parts available - like the ones that go from the Magus Bubble Doser to the Tubing.

Hey there! Most dosing unit options utilize the 1/4" type of tubing. However, the tubing with this doser is softer than the polyethylene tubing that fits those bulkheads. Unfortunately, there are no bulkhead options that would work for this pump's tube. :-(

Does this work with the Neptune Systems' DOS?

Great question!
The BRS tubing will not be a good fit. I have included the correct tubing below.
