In my nano I point both returns slightly and toward the center of the front glass. In the cube like tank this creates a gyre with the water circling the tank in a vertical circle. You can do this in the red sea max by adding another power-head in the opposite corner form the returns. Alternatively you can point the stock returns with one pointing slightly up and toward the slightly toward the center of the tank and the other down and nearly straight. It's all a matter of preference and how your rock-work is set up. The main thing is you want good flow throughout the tank with no dead spots.

 

With Nano's like the RSM where both returns are on the same side of the tank I recommend an additional Powrehead in the opposite corner.

 

There are several members in Lehi. You're welcome to come check out my tanks as well and take some sand with you to seed your system. I have a 28G Nano, 55G Frag Tank and a 10G clown tank.

Let me know!

22lbs of rock should be fine but more would give you a bit better filtration. I would wash the old sand in clear water and put it in the new tank 2-3" deep. I would also seed it with a couple cups of live sand. You ought to be able to get some live sand here on the board for cheap or free. There are a lot of good hobbiests here on the board from your area. There has been quite a bit of live rock for sale here too.

 

If you have any other questions ask away we are a friendly helpful group. You could also do a search on this board that will come up with a lot of useful information.
