I am designing my first saltwater tank and first sump. DT = 85 gal, Sump = 30 gal, I have 10 feet of head. The sump will be located in a utility room in my basement, so noise is not an issue. I expect I will have at least 4 45 degree couplings on the 1" PVC return line. I'd like to have a least 5x turnover through the sump, so I'm shooting for 450gph after accounting for head and elbows. Recommendations? TIA - John
