Syringe Adapters For Aquarium Dosing

by a_str8

I use oral medicine syringes to measure chemicals for my fish tank. These adapters make it really easy. Just stick the syringe in the hole, invert the bottle, and pull out your required amount. These adapters fit API CO2 Booster and Tetra Aquasafe Plus . 3/2/17 Update: After a couple of days, the API CO2 adapter started to leak. I uploaded version 2 which fits tighter. Whichever version you choose, you may have to do some scaling in your slicer to adjust the fit
