After two years having a tank on the second floor and a number of times falling asleep when making water up my ceiling started to show some scars ( Some of you guys saw the scars at my meeting).. Well the last month or so the ceiling was getting worse paint was peeling and always felt damp.. sheet rock had swollen and started to drop.. I have been getting frantic thinking my tank/sump had a leak and was always looking but didn't see no wet/damp spots around the Tank/sump/Stand so yesterday I pulled up a part of the plank flooring in front of the tank to see what was going on but it seemed dry but could only see one part of it due to the way the joist was running.. this was driving me nuts so i decided to take a look from the dinning room ceiling.. well the little look turned into a big look but i think i know what was causing it now..wife and kid had a few small water spills on the bathroom floor and the water ran down the joist close to where the tank is and with the humidity it was wasn't drying out..Anyway some pics of my dinning room ceiling now.. Just glad it wasn't the Tank
