If you ever hated doing that 0.1ml tank water dose. Hanna released a pipettor to dispense that 0.1ml accurately. http://hannainst.com/graduated-pipette-100-l-hi731339p.html I found out about when I was at Neptune Aquatics last week and noticed that the case for the Calcium checker got really big. Saw the pipettor in there and went looking for the part number. Ordered it and just used it. Definitely makes it easier. I also went ahead and ordered a 1-10ml adjustable pipettor from Amazon. So now no more squinting at tiny graduated lines on a small syringe!
