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.

Product Questions
Long story short, yes you can place it below the dosing container. :-)
it is able to handle up to 2 pumps and has independently controlled outlets.

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).
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.

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.
