Drew's Dosers feature a low flow rate of about 1.6mL per minute that makes them perfect for dosing 2 Part. Two Drew's Dosers are needed to dose 2 Part. These are the pumps that we use on our own systems.

  • Will not back siphon
  • Super quiet
  • 1 Year Bulk Reef Supply warranty
  • Includes 10ft of tubing, directions and 100mL measuring cup for calibrating

      • The flow rate of a Drew's Doser is intentionally 1.6mL per minute which makes it too slow for most auto top off needs. With the addition of an inexpensive digital timer Drew's Dosers will provide a fully automated calcium and alkalinity dosing solution. Two Drew's Dosers are necessary to dose 2 Part. The tubing set typically lasts 1-2 years depending on amount of use. Each Drew's Doser includes 10ft of tubing. Please note that the flow rate of each pump will vary slightly and should be tested before use to determine the exact flow rate. BulkReefSupply.com offers a full 1 year replacement warranty on all Drew's Dosers.


      We do not suggest using this pump for auto top off systems.

Does the doser need to sit above the dosing container? Will placing it at the same level or lower create a syphon? Thanks!

Great question! You can place these peristaltic dosing pumps anywhere, in relation to the dosing container, and there is no worry of creating a siphon! The peristaltic dosing pump head pinches the dosing tube inside so there is no chance of a free flow siphon.

Long story short, yes you can place it below the dosing container. :-)

what timer works best with it ??

Great question, One basic timer we would recommend is the EcoPlus Dual Digital Timer
it is able to handle up to 2 pumps and has independently controlled outlets.

I have the inline going clockwise as it made since that it would circle through then dose the tank-is that correct? I feel stupid but not sure. :)

Hey Claralice,
That is correct, it should go in the tube on the left and out the tube on the right (assuming the tubes are pointing towards you).

Hello. I want to know if I can use this pump to dose kalkwasser? I have a 18x18x18 rimless cube. Thanks.

Hi Edwin,
This pump wouldn't be a very good choice for kalk as it isn't meant to run for that long. For kalk you would want to look at something like the 50mL doser which is faster and wouldn't need to run as long.

Can the flow rate go down to 0.2mL/min?
Question by: Ling on Sep 24, 2013, 11:01 AM

Hi there,
The actual flow rate on the pump is not adjustable. It will always flow at 1.5mL per minute that it is running. You control how much solution you are dosing by adjusting your timer and thus how long the pump itself runs for. If you want 15mL, you would run it for 10 minutes. If you wanted .75mL you would run it for a half a minute.
