I dont know of any way to stop the leaking, but if it were me I would be in a hurry to take it down and repair it.
Well, i kinda hope that was the case. But i keep measuring the water level and even switched off the fan to minimise evaporation, but i notice the water level keeps getting lower and have to top up water constantly until the new tank arrives.JanS said:Just another thought. I've heard a few people now who have thought the tank had a leak from the bottom, but like you couldn't find the source of the leak. It turned out it was just sloshed water that settled into the bottom frame and started seeping out.
Before you get drastic, try drying out the bottom frame and see if it keeps doing it. Of course that's unless it's really losing water at a quick rate.
