The Dosing Pump Hose Connector Holder by DVH Aquatics is designed to provide a secure and efficient way to dose liquids in your aquarium. This innovative holder uses acrylic tubes that attach securely, eliminating the curling common with traditional tube holders. The angled bottom cuts ensure that liquid flows out without splashing onto your aquarium walls or sump baffle. Simply push any standard dosing pump tubing over the acrylic stems, mount the holder to your aquarium wall or sump baffle, and insert the tubes for a sturdy delivery system. Made from 100% PMMA acrylics, this product includes four acrylic tubes, a mounting bracket with set screw for secure placement, and large diameter connections that do not hinder flow.
