Should be a nice tank as soon as you, buy or build a stand capable of withstanding the wieght of 75 gallons of water( 1 gallon wieghs 8.35lbs ) thats 626.25 lbs sitting on top of a dresser not built for that purpose, the odds are against you, is it worth your investment? Also as mentioned youll want to silicone those rocks for sure, then you may want to checkout the thread in this forum pertaining to the "gallons per inches" and rethink how many fish you should really be putting in a tank that size..75 is bigger then a normal household tank but your overloading that tank with fish and the result wont be good. GOODLUCK!
