I scored this tank, stand, and sump for $100. I had to reseal the tank itself, and redo the fittings of piping as well. tank and sump were extremely filthy, and took several washes to get it to where its at now. im wanting move the live rock into sump or most of it atleast, how should I go about breaking the live rock into smaller pieces, maybe a flathead and hammer?
