Yesterday morning, my tank was fine, I come home at 5:30pm and My stand is soaking wet and there's only about 3 inches of water in my tank!! I refilled my tank and look for any crack or leaks, but I don't see or feel anything happening. Just 5 minutes after wiping it down, it's wet again. I think that it's coming from my Power Filter, but just to be safe, I put all of my fish (yes, they all survived) in my other 10 gallon tank. I put all of my plants and decorations in there, my Sponge Filter, my heater, and I tranferred my hood too. They seem to be doing fine, but I don't know what's wrong with my oother tank/filter. Can someone please tell me what to do, and possibly what type of silicone to get??
