I'm looking for 1.25 oz accurate dropper bottles or something similiar to these to dose liquid ferts from (20 drops = 1 ml):
I have old AP test kit bottles like that, but obviously I won't be using those in my tank due to the chemicals they once contained! I want something I can refill, so that I can put an end to syringe measurements from the big bottle and just count drops instead. Any ideas?
Edited to say I'd prefer if they weren't clear in color, as I believe the ferts say to not expose them to light.
