I have an old yet tough wooden dresser that Im planning on using as a stand for my 100 gallon (400L) aquarium. The tank itself overhangs the stand by 1.5 inches (approx 3 cm) on eachsides. A carpenter and an architect both said it should work out fine. Like I said, no worries about the way and the materials used to built the stand but my question is would it cause a problem if it overhangs the tank by a bit?
