I have a 120 reef tank (48x24x24) with 1 one inch drain and 1 3/4 return line. Refugium holds 30 gallons (32x16x16) and it will be underneath the tank. The Skimmer is a Reef Octopus XP- 2000 internal skimmer I have two MP 40's (and a couple of Koralia 750's if needed). I need to have a recommendation for a return pump, the quieter the better. I don't need it as a power head, as you can see, I have that taken care of, but I will be running it through a UV sterilizer which I also need your recommendation on. All of this will be plumbed with PVC. My sump is drilled for an external pump, but would do an internal if it meets my criteria. I'm actually looking at an Eheim 1262 pump. is this a good choice?
