The 6 Best Dosing Pumps
This wiki has been updated 17 times since it was first published in January of 2019. An automated dosing pump is a useful tool that helps keep your aquarium’s inhabitants healthy and thriving. In reef tanks, these systems ensure that invertebrates receive a proper supply of the calcium and magnesium they require. In freshwater environments, they administer essential nutrients needed by plants for growth. Here we rank these devices for reliability, ease of operation, and price.

The all-inclusive Aqua Medic Evo 4 made the top spot on our list, as it comes with all you need for a four-channel system that can add water, nutrients, and supplements to your tank. Just connect the handy, wired panel for a full range of controls and an easy-to-read, backlit LCD.
If you’re in need of more than four pumps, look to the Eshopps Master, which, when combined with a separately sold slave unit, accommodates up to eight channels. It’s refreshingly easy to program, so you’ll be up and running in no time.
The Neptune Systems model featured here is an expansion module that connects to the manufacturer’s Apex hub. It’s great for automatic water changes, where one pump removes old water from your tank, while the other adds new water.
No matter which you select, each of the choices listed here is a quality model that will reduce the amount of work on your part and help provide a stable, healthy environment for your aquarium.
