I went and did kind of a silly thing today. Sprung for a pair of new MP 40's. Do I NEED them? No. I am a bit unhappy with the flow from the 4 x icecap 2k gyres in this tank so considering the "sale" price and how quickly they seem to sell at a decent price I thought I'd try them out. I've always been enamored of the wire & electronics being outside the tank.
With this tank footprint (false wall overflow so no back of tank) and the rockwork I have, how would you set them up? Opposing in the middle sides or one in the front left and the other in the rear right? What flow pattern to use and velocity? I can use the gyres to supplement if needed or just for backup.
