I am doing a120gal. Reef tank thinking of a40 gal. Sump. I am looking at the reef octopus,bubble Magnus,and eshopps 300 skimmers any suggestions. Also the sump is in the room below the tank, the pump will have to return the water 10 feet up.any ideas on a pump or pumps for this, submersible or external? How about uv lights, some use some don't, some keep them on 12hrs,any thoughts? Thanks so much.
