well construction is starting soon on my 12' by 8' by 3.5' tank it probably wont have a window to cut down on cost a little, but i wont be skimping on filtration. Im planing on putting an advantage 5 bead filter as the primary filter on it. my question is what size pump should i run and does anyone have suggestions for the most energy efficient pump that would have a sufficient flow rate for this size of tank? the stock list will include a pacu a RTCxTSN and 5 oscars.
