Hello all. So outside my apartment complex is this tank (pictured) below, sitting beside the dumpster areas. It has one crack going lengthwise from corner to corner. Do you all think it's worth trying a silicone repair job and salvaging it? I currently have a 20 long tank and am in the market to upgrade to a 55 gallon.I'm not sure what size this tank might be. It looks a bit longer than a 20 long, definitely deeper than a 20 long and definitely taller than a 20 long. Any input would be appreciated.
