I just ordered 6 bottom springs from COV. The first did last me a few days until it "collapsed" ? I just tried 3 mor but everytime something goes wrong. I finally put a spacer in (on bottom and it turned black, the springs as well, they were copper colored and are now black). I only have a few left and don't want to mes them up too. What's going on here, or rather what did I do wrong again? Using my Stealth with a viva nova tank but that should have nothing to do with it, also tried different buttons but again, spring immidiately turns black. Is there a wrong way I can put the spring in? Sorry for having to bug you guys constantly, I don't know what's going on anymore. Thanks so much.
