Hydros minnow pump question?

BriDroid · Jul 15, 2025

If I add a minnow to my collective, can I have it dose 3.8ml, and then have it run in reverse to clear the line out?

I can’t seem to find that info anywhere.

The Minnow can run as low as 25ml a minute and it will run in reverse also. You would have to add to the dose the amount it takes to refill the lines to get the amount you want out. I have not tried it since I do not dose anything that needs to be removed from the tubing.

Ok, I setup a test on my unused Minnow dosing pump. Below is the output setup and the two schedules used. Also the log is below. I reset the time a couple of times so there are three dispenses.I figured I would use 5ml as the amount t takes to fill the tubing but you will need to figure out how much it really takes and add that to the dispense since the lines will be empty to begin with. The first schedule does the dispense and the second one empties the line running in reverse.

Thank you so much! This is what I wanted to see work! I really appreciate it!
