Automating Additives with the JEBAO MD 4.4 Dosing Pump
The MD 4.4 takes the guesswork out of dosing fertilisers or reef additives, scheduling precise amounts so your tank stays stable while you are at work or away. Its AP mode runs without a router, handy if your tank sits in a corner of the flat with weak Wi-Fi, and the low 12V supply keeps things safe in humid rooms. For Singapore reef keepers, automated calcium, alkalinity and magnesium dosing smooths out the swings that warm water and active corals can cause between manual top-ups.
Planted-tank hobbyists can use it for daily micro or macro dosing, which suits the EI and lean methods well. We suggest calibrating each channel before trusting the schedule, mounting it above the tank to avoid back-siphon, and securing the lines so a knocked tube does not dump additive. Refill reservoirs on a routine so you never run a channel dry mid-cycle.
Browse more in water pumps, and read our auto-dosing setup guide and EI dosing guide to get your schedule right.
