Maybe, maybe not. The discovery of water anywhere it isnt supposed to be can cause panic, even in those that have been aquarists a long time.
First, stay calm. Check the area around the stand. Are there wet places on the floor? Water marks down the stand? Water marks down the outside of the tank? Make sure you havent overfilled the tank (I know, that sounds crazy but sometimes it happens). Is your water level dropping significantly more then normal?
Check all of your items on the tank. Check any cords, tubes, the canopy, seams, anything that hangs. Look for places where water can seep or splash. If you added an air pump for bubbles make sure it isnt splashing water out. Those tiny droplets can add up quickly. Check the filters and make sure they arent overflowing (I had a filter built into the canopy and the filter clogged and overflow started leaking out the back). Check the seams around the tank for accumulated water.
Then, if you haven't found a cause, take something and soak up as much water as possible. Watch the area closely and see if more appears. If it does and you have eliminated everything else, then I would think about it being a slow leak and take appropriate action.
