Frequently Asked Questions
Can this hold more than 4 tubes?
No — the holder is designed for exactly 4 dosing lines. If you run more lines, add a second holder.
Does it fit any aquarium rim?
The holder clips over standard-thickness glass or acrylic rims. Check that your rim thickness is compatible before ordering.
What are the quick-connect tips for?
The tips snap onto the end of each dosing tube, allowing you to attach and detach lines from the holder without tools for easy maintenance.
