Other than Panta Rhei pumps what other power heads have you guys and gals found that can really move water over and 8 ft. span? I have an eight ft peninsula and I am too stubborn to put power heads on the far viewing pane. I have a bottom based closed loop which takes care of the bottom one third and I have the top one third managed by strategically placed return nozzles. Middle one third is my problem....tank is 43” tall.
