Ok so I changed my carto for the first time today and the o rings are oversized? When I go to put them back in the keep hanging out the side or falling off. Anybody else have this trouble? I hope when I change my other carto its not the same way. I had to take something and push the o rings up as I put it in the tube.I knew something was diff. when I took the carto out and both o rings fell off the rubber pieces. When I tried to put them on I could see they didnt fit like they should. I guess I should buy new o rings but I dont feel I should have to. Gonna change my other one tomm and will post back if they are the same way. I have 3 of these tanks one I havent even used yet just a back up I might check that one also. There the mini subs with the 3.0 ohm cartos..
