I have a 60 gallon cube with about a 20 gallon sump. My sump is located in the basement so I have 11ft of return line. I am looking at the mag drive pumps. I have a Iwaki 800 gallon pump but it just doesn't have the head pressure to push 11ft. Any recommendations. I am looking at the Pan World 200 PS this has a flow rate of 1750 gallon with 39FT of max head pressure. Or a Iwaki MD70RLT with 1500 gph and 31.8 FT of head pressure. What do you think?
