I got my inline uv sterilizer today, but the barb sizes were different than my eheim filters so I got a coupler to go from 1/2" to 3/4" hose. Its brass though and the water does touch it so I was wondering if it could release anything bad into the water. Its for plumbing so I figured it would be fine but thought it was worth asking.
