did the usual WC yesterday, took some fish out & put the hood back on & was plugging everything back in & there was water dripping from under the stand. my tank is on a steel stand & has a board then poly & the water was dripping from a corner. its at the back & no water was spilled because i hadnt started filling it. it dripped for about 2 minutes, enough for me to panick & we took the hood off & statred to try & catch the fish & change tanks, then it stopped. now i dont know if there is a crack in the bottom, but surely it would have kept on dripping??? so i dont know if i should strip the tank or leave it, haven't replaced the water i took out yet, thought i would get up this morning to wet carpet!! checked the air lines to & they were dry so i have no idea where the water came from. :-?
