I wouldn't try it - the tank could weigh 400 - 600lbs when full of water, gravel etc. I wouldn't put anything beyond a 20g on something not specifically made (either by a store or DIY) to hold the weight.bizzy420 said:i also have a dresser, that looks pretty sturdy, but im not sure. i know that tanks can get very heavy. is it safe to leave a tank 45-60 gallons on a dresser?
