water current

[CubicGgW]

i have two PH in my 20 gal tank which i tried to make a cross current from them. but i have a question, what would happen if one of the PH is stronger?
well, i know i wont get much of a "x" shape current, but i'm hoping that there would still be currents or water movements everywhere in the tank.

It wont mater much if one is stronger than the other. Having them positioned so they are blowing toward eachother will create a good random disturbance of current that makes the water motion more natural than a constant adn steady jet stream of water.
