The ATI DP-6 is an aquarium dosing pump equipped with 6 programmable channels you can use to automatically dispense liquids like additives, foods, and even top-off water.

Most dosing pumps for reef tanks are only capable of dosing 4 liquids and require expensive sold separately extensions to dose more. The DP-6 from ATI has 6 professional-grade peristaltic pumps that you can program or operate manually and it costs less than other auto dosing pumps in its class.

The DP-6 doser has a controller built right into the top of it with a LCD display and touch pad to easily schedule your dosing regimen. You can automate 2-part calcium and alkalinity, Kalkwasser, trace elements, live or prepared foods, and even fertilizers and liquid CO2 if you have a planted tank.

If you have a reef tank, it is strongly recommended to have your essential element levels tested regularly by
ATI Labs while using the ATI DP-6 Dosing Pump. You can then fine-tune your tank`s health by dosing ATI Elements instead of doing water changes to try and correct water chemistry.

The elements and nutrients corals and invertebrates use to survive must be replenished. If a reef aquarium is fully stocked, they may need to be replenished daily. Setting up a reef dosing pump to administer the proper amount of elements and nutrients for your reef tank can be an enormous benefit. Not only to your sanity, but to the animals that call your tank home.

The peristaltic dosing pumps used in the DP-6 are perfect for dosing fluids into aquariums because they deliver them at a safe, precise and controlled rate. They are also self-priming and can draw fluids/supplements out of a
dosing container, into the pump and then into your aquarium without any harm to the pump itself.


The DP-6 is designed to be used in conjunction with ATI ICP-OES Water Analysis (a mail-in lab quality water testing service) and ATI Essentials and ATI Elements.

When you arm yourself with truly accurate water quality measurements, the elements your reef needs, and a means to safely deliver those elements into your aquarium, performing partial water changes to correct water chemistry or compensate for trace elements will became a thing of the past. You will ultimately save time, money, and grow more robust and colorful corals!
