Well I bought a Used 135 Gallon Tank from a Owner of a Boat Business,72 inches long Tank ,Top and Cabinet for $350.I bought 110 pounds of Paver Sand from Lowes and put in the Tank.And put in all my Live Sand and Live Rock from my two Old 55 Gallon Tanks.So far everything seems okay I finally have a Large Tank :lol: that I have always Wanted.Has anyone ever combined two Tanks like this before in this Manner?.
