I would like your opinion regarding water flow in my 72” x 24” x 25” tank. Currently, I have a Maxspect XF350 Gyre pump pushing water across the surface of the tank, mounted on one end. It creates a good gyre across the tank, in fact I have to dial it down or it displaces too much of the sand bed. My question is do you think I need another powerhead mounted opposite of the Maxspect? The reason I ask is I don’t know that I’ve ever seen a tank with only one powerhead.
