Water circulation in a 75g?
 
I'm currently putting together a planted 75g aquarium that will soon house a pack of Sterbai's , Cardinal's and Angelfish. What would be a good size Hydor pump to get some water circulation going in the tank? I don't want to stress anybody out with to much water movement but would like a little flow to keep the water moving. Any suggestions?

No power head is needed ... just the canister filter is more than enough.

Agree. A canister rated for the tank size is more than adequate. For the fish named (and plants too), you do not want fast currents. I position the spray bar along an end wall, with the line of holes aimed into the wall itself at a downward angle so the water flow is directed down the wall and across the tank [the filter intake should be at the opposite end from the spray bar].

Right. None of those fish appreciate much current and your plants will do better with less also. Your filter will provide more than enough circulation.
