Hello to all , am planning to get a 240 gallon 96 x 24 x 24 tank for two silver Aro's Eventually. I have a 40 gallon 3 x 12 x 18 am using as a grow up tank. any suggestions as to what type of filter (thinking of getting two eheim pro 3's ) , gravel , heater , etc. I need for the tank looking at black gravel as substrate driftwood centerpiece and some plants to decorate tank. Will be of great help to get things right the first time and not make a very expensive mistake. looking at maybe $2000 to spend for the whole lot
