    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?

    Is that GPH@ 0' or is that taking in account for plumbing? Are you using a sterilizer, or any other accessories?

    Sorry if I hijacked your thread. Is my 550 gph return enough for my 120g? I have 40g sump. Thank, sorry again if I do.

    I run a 740 GPH return pump on my 125. Including head loss I would guess I am getting only 650 gph. I would say your fine. If your flow is too fast and you have macros you lose the effect you are looking for.

    I have the exact same tank and use a gen-x pcx 40 external. 55w 22ft 1190gph and have it mounted on a soft pad so no vibration and quite. No heat in the water like internal return pumps would have.... don't do internal if you don't have to IMO

    I'm now considering using Reeflo's Blowhole 1450 adjustable pump. I called them today and asked if they still had that heating problem they had with their pumps last year. They said they revised and updated their pumps and there's no longer a heat problem associated with those pumps.

    I switch from a mag 5 (to loud) to an OceanRunner 2500 (around 600 gph). 5ft length to the top of the tank from the sump w/ one 45 degree and 1 90 degree bend and mine is just fine. Plus the pump is ultra quiet and love it!! I really wanted something around 750gph however Oceanrunner didnt have anything. The next size they had was the Oceanrunner 3500 but it is way to powerful (it is comparable to the mag 9.5)..it would drain my sump before I could even have it filled..

    I am definitely not complaining about the Oceanrunner. It is a great little pump and runs solid!
