I found a miraculous way to move m tank in my apartment. Due to a recent TV purchase i needed to move my tank across the living room. I bought some furniture sliders that are absolutely awesome. I took about 6 gallons of water out, put it on the sliders and moved it by myself easily. Granted i have a 30 gal, wooden stand, and sump. But i was still absolutely amazed at how big of a difference they made. Here is teh link if you find yourself in a similiar situation or if you wish there was an easy way to move it.
