Update:
I wanted to upgrade my Tunze 6025 powerheads to 6055 so that I can get more random flow but after a little research it turns out the nanostream powerheads by Tunze are not ideal for cube tanks. The flow is too direct so I decided to go with a Vortech powerhead instead because the flow pattern is much wider.
I also got the battery backup so that if the power goes out it will stay on for 30hrs. It has another port for a 2nd Vortech and they would share the battery so it would be 15hrs each.
So far the flow is incredible. As soon as it was turned on detritus got kicked up for area's my nanostreams did not reach. I am glad I went with the MP20 because is more than enough flow.
