Ideal as an Auto Water Change (AWC) System

  • Accurate Dosing ± 0.01 ml
  • Track Dosing History on the Reef Factory App
  • Advanced Control and Features


High flow rate - about 1L per minute. This pump quickly moves large volumes of water. Using two of these pumps, create a reliable auto water change system and eliminate the water change chore from your to-do list.

Alternatively, if you know the amount of water that evaporates from your aquarium each day, you can program it in the Dosing pump Large and have it pull water from an ATO reservoir to keep your tank topped off and salinity stable.


Manual Dosing Function

The manual dosing function allows you to increase or decrease the dosage once or repeatedly. This allows you to easily change your dosing schedule temporarily. Alternatively, you can select the "Now" option and the dosing pump will add the extra dosing amount immediately. At the end of the set manual period, the pump returns to the previous dosing schedule. 

Additional Functions

The Dosing pump Large can also estimate the amount of fluid remaining in your reservoir. All you need to do is enter the volume of your dosing container and the amount of fluid currently in it. Once complete, you'll have a convenient display of the estimated liquid remaining on the Reef Factory app. When the level drops to 10% of the total volume, you'll be notified automatically.

The App also displays prior dosing history, so you'll have a log of the amount added for that particular dosing liquid.

Product Questions

What’s the maximum head pressure in feet and maximum pumping distance?
Question by: Andrew Sweeting on Dec 16, 2023, 2:54 PM
Hey there,
Thank you for reaching out to us. The max head pressure is about 18 feet. It does not have a listed max distance.

Please let me know if you need anything further and take care!
