Tom__in_Maryland Posted November 25, 2020 Share Posted November 25, 2020 has anyone else experienced air valve corrosion after one month this is all fresh water fishroom with Aq Co-Op air pump which is fantastic Link to comment Share on other sites More sharing options...
TheDukeAnumber1 Posted November 25, 2020 Share Posted November 25, 2020 I think these valves are brass with a chrome finish so they can develope a patina. I use one of these in my brine shrimp hatcher as an air/dispenser valve and it has developed a noticable green patine on the inside of it. Looks like yours are getting wet often. 1 Link to comment Share on other sites More sharing options...
lefty o Posted November 25, 2020 Share Posted November 25, 2020 like mentioned above, most metal air valves are nickel plated brass, and once the nickel is compromised the brass will corrode, or get verdigris to be more specific. Link to comment Share on other sites More sharing options...
farrell989 Posted February 24, 2021 Share Posted February 24, 2021 Can this hurt invertebrates as brass is part copper? Link to comment Share on other sites More sharing options...
lefty o Posted February 24, 2021 Share Posted February 24, 2021 no, as they arent to be submersed. 1 Link to comment Share on other sites More sharing options...
