Aquarium automation is one of the hottest trends in aquarium keeping. What’s aquarium automation? It’s the use of electronic devices to control important functions in your freshwater or marine tank.
The primary goal behind aquarium automation is to make keeping an aquarium easier by continuously monitoring and controlling important parameters. Automation also helps in maintaining a consistent aquatic environment, which helps keep fish, coral and plants healthy and vibrant.
Dosing pumps are one of the primary types of aquarium automation devices. They’re designed to automatically add precise amounts of additives to the aquarium water. The idea is to consistently add just the right amount every day to ensure a stable aquatic environment. Dosing pumps can even be used to automatically change aquarium water!
What kind of aquariums benefit from a dosing pump?
Reef aquariums are the primary candidates for automated dosing pumps. The live corals, clams encrusting coralline algae and other reef-building organisms need a steady supply of calcium and magnesium. Marine invertebrates extract these minerals from the aquarium water to create calcium and magnesium skeletal mass, shell material, and encrusting algae biomass. If there are not enough minerals in the water, coral growth slows down to unnatural levels.
Many reef aquarists are concerned that essential trace and bio-elements can drop to growth-limiting levels. These elements include strontium, iodine, iron, copper and manganese. Other additives include proprietary blends of amino acids, vitamins and potassium. You can even use the pump to add freshwater to compensate for evaporation.
Freshwater planted aquariums can use a dosing pump to add essential plant nutrients like phosphate, nitrate, iron and essential trace elements. The idea is to keep the plant growth maximized to out-compete algae growth. Too much fertilizer at one time will over-stimulate algae growth. A small daily dose of nutrients gives the plants what they need without creating nutrient-rich water that causes algae problems. Daily additions of liquid carbon (CO2) is easy when it is managed by a dosing pump. The aquatic plants will always have a supply of carbon to stimulate lush growth.
How do dosing pumps work?
When dosing pumps were first introduced to the aquarium hobby, they were nothing more than industrial and medical devices. They were large, heavy, noisy and very expensive. Because these dosing pumps were not designed for aquarium use, they required lots of adjustment to make them work. Replacement parts were hard to find and very costly. Fortunately, aquarium product manufacturers worked to develop dosing pumps designed specifically for the aquarium hobby.
Today we can enjoy the quiet reliability of purpose-built aquarium dosing pumps that cost far less than the early models. All dosing systems use a peristaltic pump design. This type of pump consists of a series of rollers attached to a central rotor. As the rotor turns, the rollers press on a flexible hose inside the pump housing. As the hose is pinched by the roller, fluid is forced through the tube. The action of the rollers serves to gently pump fluids through the pump in a reliable, consistent flow rate. The amount of liquid added with each pump cycle depends on the diameter of the hose inside the peristaltic pump and the duration of the pump cycle.
Today’s designs fall into two categories. Stand-alone dosing pumps have built-in capabilities that allow for programming the dose rate and timing. Modular dosing pumps are more advanced, requiring connection to a separate control module. This modular system allows many devices to be controlled by a single “brain” module. Often the entire lighting, dosing and filtration system can be controlled with a wireless app from home, office or anywhere there is an internet connection.
Which dosing pump is right for me?
There are a variety of dosing pumps to choose from.
If all you want is to top off the tank when water evaporates, an automatic top-off (ATO) system is the way to go. While these dosing pumps can be programmed to periodically add water, none senses the water level like an ATO.
If you’re looking to add multiple additives and control exactly how much is added and when, dosing pumps are for you.
Our recommendation is to read through the reviews and see which models best suit your needs for dosing and automation capabilities.
Aquarium Dosing Pump Reviews
1. Jebao DP-4 Programmable
The Jebao DP-4 is a low-cost, four-head dosing pump. Each pump can be programmed to dispense a precise amount of liquid up to 24 times a day.
This allows a user to keep their tank parameters stable, and removes the need for mixing supplements every day. The controller is easy to set up and use.
Each pump can be programmed to function individually.
The DP-4 is perfect for any tank, as it allows for dosing in both large and small increments. The DP-4 comes with a power supply and is plug and play after it is calibrated with a 100mL graduated cylinder. An extra slave unit can be added to bring the pump count to eight.

2. Kamoer F4 Pro WiFi
The Kamoer F4 is their latest dosing pump design. Unlike the previous version, the F4 Pro has no LCD display or buttons.
All functions are controlled through Wi-Fi. Each four-pump unit includes a Wifi connection which gives you control of the doser via iPhone or Android devices.
Periodic software updates are painless. The app sends updates to the F4 PRO via WiFi. No wires or physical connection is required. The user-interface is friendly and intuitive to help you get up and running quickly.
The Kamoer F4 Pro features three operational modes: Automatic, Manual, and Custom. Through the app you can set the start and stop times and dial-in how much to dose during that time period. The scheduling section of the app lets you select alternate dosing days.
An important feature is the option to set delays on channels. This allows one substance to be added and given time to disperse in the water before another pump doses a different chemical. This prevents two concentrated additives from being added at the same time, eliminating the chances of chemical precipitation. This makes it easy to use two-part calcium products, trace elements, liquid prepared foods and even live pods.
Note that a simple single-pump doser is also available.
- Small footprint
- Fully programable
- Easy calibration
- Battery backup of settings
- 1-year warranty

Many thanks for your reviews, especially for the Jebao DP-4. I’d very much appreciate your thoughts on an idea I have for using the DP-4 in a non-aquarium application. I work in a biochemistry research lab and it seems to me that the DP-4 might allow me to perform some of my analytical procedures at a fraction of the cost of laboratory-grade peristaltic pumps. I would like to use the DP-4 to pump four salt solutions in parallel at the same rate, about 10 ml/hour for a total of about 5 hours. Do you think that the DP-4 would allow me to do this? That would be a great help for my work. This would be a routine procedure in my lab.
Thanks in advance for your advice.
Great question Martin! The Jebao DP-4 is indeed modeled after laboratory-grade peristaltic pumps. The technology is well-refined, so it should work for your project!
