Searched everywhere for nylon barb to make a Rex Grigg Reactor with. Does anyone know where I could buy a couple of these in 1/8" barb made of nylon or pvc?I used brass hose barbs for my inline CO2 reactor for several months and didn't have problems. I had Cherry Shrimp in the tank for a week or two, also without issue. I did recently replace the brass barbs for nylon ones though. I did that for piece of mind since I read alot of negatives regarding brass.
