I just bought a new reef octopus and upon plugging it in i realized right away what others have apparently realized...it sounds like a **** waterfall. i was wondering if anyone knows where I can buy this output vent from. i tried making my own but the skimmer is metric so i have been unable to find 40mm pipe. any help would be appreciated thank you.
