Dosing tube holder needed for Trigger Systems Sump with 3/4” lip..

[joe-ejs]

Hello.

I am setting up a dosing system on my tank and have a Ruby Red Triggers systems sump which has a 3/4” lip all around the top edge. I am trying to find a tube holder that will fit. Has anyone run into this and found a holder?

also, my sump was used and does have two pre drilled holes near the top with standard RO tubing connectors which are larger than 3/16” doses tubing. Is there an adapter where I can utilize the existing larger RO size tubing and connect it to the dosing tube?

any advice/recommendations would be appreciated

If your holes are bigger than your dosing tubes, put your dosing tube through the hole and put a zip tie on the bottom so it doesn't pull back out easily but can on purpose. Could also wrap the tube with electrical tape making an edge that fits through when you want it to. Not on its own.
