I would NOT place a gyre below the overflow box as placement of the magnets will have water going over it inside the box. Because you have an apex, I would get the tunze 6095 wideflow pumps with controllers and hook them up to your apex and have them point to opposite corners. I can share my code with you and it works awesome!! The tunze's alternate left and right to opposite cross corner and then both come on, and then both come off. I have them set to do this every 17 seconds. The mp10 on detritus mode sweeps from the back wall from left to right. I have a bare bottom as you can see, and no almost no detritus except for hermit excoskeletons and old frag plugs) No hair algae, diatoms... Everything collects bottom right back corner under my xenia. I call it the boneyard. Another option, is two gyres on opposite sides of tank. One from back left corner horizontal near top from back left to back right, and the the other from side right to side left (The gyre currents would be perpendicular to each other). I would use the same program. This way you have counter swirl flow similar to mine. I went with tunzes (but either would work great) because they last forever, and would def keep your MP10 like I have for back corner as that makes a very big difference (I have it on the 2nd lowest setting). If money was no option, a total of 3x mp10 would probably be awesome as well with the advantage of having good nem guards) Flow wouldn't be as wide or diagnol across the tank, but wouldn't make a difference as the detritus mode and variable on these pumps.Very exciting. I'm building a 60 cube as well and spent the better part of the day thinking about flow as I did chores around the house and ran a few errands.
I already have an MP10 and the apex module so I'm considering adding a second MP10 and placing them mid-tank on the back wall. I'm also considering the Icecap 2k and placing it just below the overflow box.
I feel like the mix of the Icecap 2k gyre and a pair of MP10's along with the dual return inlets should create a nice mix of flow at 50%. It may be overkill but this will be my first bare bottom tank so I want the option to crank up the flow.
Le us know what you decide on for circulation and good luck with the tank!
I don't think you can go wrong with that. The beauty of a cube is you can almost always set them up to have really good alternating current that swirls. If you have an apex, you can hook them up to a variable outlet and try out my code. It works great.I have decided to order the dual 2k gyres and see what kind of flow I can create.
And apex is on the list but unfortunately it will be a year down the road.I don't think you can go wrong with that.
