or do we all ahve to wing it for our own tanks:notsure:
Personally I like to try to eliminate powerheads as much as possible. To this end I have a spray bar attached to my overflow box at the return part. This spray bar is modular and I can point the seperate nozzles around the tank. I still us one MJ 1200 on the far right corner of the tank. So the best way is to have a drilled tank with internal overflow and a good return pump, then a powerhead or two.
Otherwise I would use maybe 4 Maxi jet 900's on a 72,75 or 90 gallon tank depending on your return pumps flow and your plumbing. Perhaps on a wave maker as well. But thats alot more electrical devices that way and there is more chance of stray voltage getting into the aquarium.
You can pattern a couple in the back corner pointing toward the front middle, then a couple near the center pointing toward the front corners, and or one pointing along the back of the tank so that you have flow there as well. Many options on how to do it and you will have to find what works for you.
