So I went and bought an aquarium stand for a 20 gallon long(It was supposed to be for the 15 gallon, but since I have to empty and move the 15 gallon anyway, I figured I might as well just get a bigger tank and use the 15 for a qt :grinyes. It's a Top Fin stand like this one except black. Anyone I'm assembling it myself, following the directions exactly (hopefully), but I'm just nervous that I am going to forget something or make a dumb mistake and it will collapse a day after I get the 20G on it. Soooo any suggestions or advice to help relieve me of my paranoia? I'm going to check that it's level, but what do I do if it's not? Thanks.. I know this is kind of newbie stuff!
