I'm a recent convert to tanks. I have to use a syringe to fill my tanks. I DIY my own liquids, and have found a few that I like enough to make up 30 mls at a time. My problem is that, with the 30 ml plastic bottles I have, I can't get the syringe down into the bottle, so when it gets about halfway empty, I can't get any more liquid out of the bottle!8-o Does anyone make 30 ml bottles, with the top opening large enough for a syringe to fit down in there? What are you folks doing?
Edited to add that I'm using a 3 ml syringe which is about 1/2 inch in dia
