I used brass fittings to connect my CO2 line to my inline reactor, and now I'm wondering if the brass is bad for the livestock. Anyone know anything about this? Thanks,

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.

I doubt any problems will result from it. Brass is a metal alloy between copper and zinc (mostly). Metal alloys don't dissolve or react as readily as pure metals. Not to mention its only 1 tiny barb, which won't expose much surface area to the water.

If it were a copper fitting, you might have problems.

There are quite a few members all over the world that use brass fittings for their tanks with shrimp. I agree with the statement above about if they were copper fittings, it may not be good.

Ok, thanks guys. I was pretty sure that brass would be ok, given that its a really stable alloy. And I figured copper would be a no-no if people went so far as to heat up cold water for water changes rather than run it through the copper piping from the hot water heater. Thanks for all the input-I'll rest easy now.

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?
