So I was set on doing a sump until I learned that a 75 gallon tank does not fit in my stand. Also it seems like the magdrive 24 runs about 245 watts. I was thinking of doing 2 FX5/6's and calling it a day fx5 - 50 watt and fx6 43 watt. Also I wouldn't have to drill the tank. What do you think? The sump would have to be custom made it will run me close to 500$ being sump alone not including media and pump and all the plumbing equipment (drilling, bulkheads, pipes, tubing.) The dimensions I would be able to fit is 48"x18"x16" would be roughly 60 gallons. If I go the fx5/6 route depending if I buy used or new can run anywhere from 300-600$. Obviously the higher price would be for 2 brand new fx6's but I see tons of used fx5's for 150 or less. I'd like your opinion on what your take on this is because I can't make my mind up. thanks guys
