i have a question on where to place an mp40 in my tank. im guessing it doesnt really matter but i rather ask and make sure. my tank is 48x18x16 tall and i have the return on the back right corner (ive added a pic). im planning on putting it on the left side facing the incoming water but wouldnt that just cause turbulence? but if i put it on the right side then theres probably gonna be a dead zone on the left side of the overflow box. any suggestins?
