Can’t seem to find a similar post.. if I’m dosing small amounts per day, throughout the day. Should the jebao 4 doser I’m using better calibrated to 10ml or 150ml that I did. I’m dosing diluted ATI in first two heads. #1 through the night and #2 through the day. But my question is my dose of 1ml per hour doesn’t seem to be working. Is it because it’s a small amount? When I’m manually dose each head liquid comes out into sump. So no airline issues. Any help would be appreciated
