Goodmorning everyone, i have a couple questions about my new Red Sea Wavemaster Pro. first off i have 4 power heads in my new 55 gallon tank and i know the wavemaster makes them alternate to essentially create waves but i dont know where in my tank the alternating power heads should be? should the two alternating be across from eachother? or on the same side?

Thanks in advance!
