Dosing pump for apex

[folsomreefing]

Hey all! New reefer here

Anyone have a recommendation for an affordable and reliable dosing pump I can easily control with my Apex? Need 2-4 channels.

Thanks in advance!

Unfortunately, neptune decided not to incorporate dosing pump control unless you buy their brand of dosing pump, the DOS. Its not cheap, but I got one used on ebay for $150. Otherwise, you can get the BRS dosing pump that can be controlled just by power. You calibrate it so you know how many mL per minute the pump outputs, then program the apex to turn on an outlet connected to the pump for the appropriate time to get the volume you want. But to track volumes and do more complex dosing schedules, the DOS is the way to go if you can pull it off financially.
