I am setting up a 450g Planet Aquarium tank. The tank is 96"x36"x30" with a 36" steal stand. The sump was built by me and a friend using is CNC machine. The sump is 90"x28"x18" and made out of 1/2" PVC sheets. I went with a Deltec 3000i skimmer with the self cleaning head. Deltec CRTT 3000 calcium reactor. Two Panta Rhei 63 pumps for flow, and L2 pumps for the returns. Two Aqualogic Inline Heaters, with two Penguin 1HP chillers. I will be also running a TMC/AAP High Output 110 Watt UV Sterilizer. I have lots of redundancy in this build with higher end equipment. I travel for work a lot, so I am trying to make things easy for my wife.
