BRS 2 Part Doser - 1.1 mL per minute

Why does BRS recommend this? The BRS 1.1 mL dosing pump is a very cost-effective yet long lasting stand-alone dosing pump perfect for trace elements and 2 part. By hooking the pump up to a simple timer or aquarium controller they can be one of the most inexpensive ways to get into an automated 2 part dosing system. With their peristaltic design, they will not back siphon and provide extremely accurate flow rates. BRS 2 Part Dosers are intermittent duty pumps and not meant for continuous operation. We recommend on/off cycles under a few hours to maximize lifespan. You will need two pumps in order to dose both calcium and alkalinity. When used with controllers like the Apex, we recommend connecting these to a mechanical relay outlet, and not a TRIAC outlet on the controller's power bar.

You will need two pumps to automate both calcium and alkalinity solutions. Timer not included **On average BRS 2-Part Dosing Pumps will output 1.1mL per minute but may vary depending on your supply of power and what other equipment is being run off of the circuit. We do suggest running the pump for 10 minutes and collecting the liquid from the output to know how much the pump will dose in a 10-minute time frame. Simply dividing the total output by 10 will let you know how much the pump will dose per minute of operation.
