Dosing Line Holder | Tank Mount | 5mm OD

Dosing Line Holder Tank Mount Overview The Dosing Line Holder Tank Mount is the terminal piece in the Stratiform dosing line holder system. It mounts over the edge of your tank or sump glass and keeps dosing lines evenly spaced as they enter the water. By separating each line at the dosing point, this holder helps reduce the chance of different additives contacting each other during dosing. It also creates a cleaner, more controlled dosing setup around your sump or aquarium. What It Does This holder supports and spaces dosing tubing at the tank edge so each line stays in its own position. It helps keep lines from drifting together, makes the dosing area easier to manage, and provides a cleaner dosing endpoint than loosely hanging tubing. Dosing line quantity options: 1 to 6 lines Dosing line size options: 5mm OD, and 6mm OD Glass thickness options: 8mm, 10mm, 12mm, and 15mm Each line position is 8.5mm wide and 40mm tall Designed to mount over the edge of compatible tank or sump glass Size Notes Each line position is 8.5mm wide and 40mm tall. Adjacent line positions share a wall, so total holder width does not increase by a full 8.5mm per line. For example, a 1-line holder is 8.5mm wide, while a 2-line holder is 16.5mm wide. Who It’s For This holder is ideal for aquarium hobbyists using dosing pumps who want a cleaner way to position dosing lines over a sump or tank. It is especially useful when dosing multiple additives and keeping line ends separated matters. How to Use Select the version that matches your tubing outer diameter. Choose the number of dosing lines needed for your setup. Select the holder size that matches your glass thickness. Place the holder over the tank or sump edge. Insert each dosing line into its own position and adjust the line length as needed. Important Notes This product is sized by tubing outer diameter, not inner diameter. This product is also sized by glass thickness. For best fit, match the holder to the actual thickness of your tank or sump glass. This holder is designed to space and guide dosing lines. It does not control dosing volume or replace proper dosing pump setup. Keeping additives separated at the outlet may help reduce direct interaction at the dosing point, but overall dosing results still depend on system flow, dose timing, and additive choice. Because this is a 3D printed part, minor surface texture or visual variation may be present and does not affect normal use. Clean, Controlled Dosing The Dosing Line Holder Tank Mount gives you a simple way to keep dosing lines organized right where they enter the system. It helps create a cleaner dosing point, keeps line ends separated, and makes multi-line dosing setups easier to manage.
