Hey, I just wanted to get some people's opinion on flow on my new tank that I am planning to get...its going to be around 30"L 24"W and 18"tall (around 55 gal). I wanted to install a reeflo dart with a om sqirt hd in a closed loop because I hear that it is quiet and uses only 160 watts...do you think that this will be tooooo much flow? If so, what other pumps would you recommend? Also, where are the best places in the tank to drill 2 drains and 4 returns for the closed loops?
