The Jebao DP-4 is a compact, four-channel programmable dosing pump designed for marine, reef, and freshwater aquariums. Each head can be programmed to dispense precise volumes on a schedule you choose, helping automate routine additions and support stable water parameters without daily manual mixing. What makes the DP-4 stand out Four independent dosing channels let you run different liquids such as calcium, magnesium, or alkalinity solutions simultaneously. Each channel handles 1 to 9999 ml per day, enabling both tiny adjustments and larger dosing when needed. Up to 24 dosing events per day provides flexible timing to spread additions across the day. Programs can be customized per channel for individual times and volumes, delivering precise control without guesswork. Compact footprint at 23.5 x 15 x 6.5 cm fits neatly under most tanks or on shelves. The kit includes a power supply and four soft tubing fixtures for straightforward installation. Calibration with a 100 ml graduated cylinder ensures repeatable accuracy (cylinder not included). All four channels operate independently, allowing tailored dosing recipes without cross-interference.
