Help ~ 2050 gph return pump too much?

[Laverna]

I will be setting up my 125g AGA tank with dual overflows (each overflow will handle 600 gph via Megaflows) to a 75g sump/refugium (aquarium to be converted and located in basement).

I am getting a little nervous with my choice of the return pump; I bought the Sequence ReeFlo Marlin (2050 gph) because I have read numerous posts stating that high flow is better. I fear the overflows will not be able to keep up with the return ~ does anyone see any potential problems?

Any info would be greatly appreciated! This will be my first experience with a sump and hopefully a positive one vs. a disaster.

I suspect the 2050gph is without a head pressure? Once you tranport water up one floor the output will go down considerably, but I cannot be more specific because I'm not familiar with that pump.

I have always heard its best to get your flow from things other than your return pump, like using the 2050 as a closed loop and then maybe 600-700gph for your return (after head loss). Also, what corals do you plan on keeping? Depending on what you want you might not need all that flow.

Yes, that is without head pressure ~ using the following chart, it looks like I will have a flow of 1860(ish) gph (I have LOW ceiling in my basement). http://www.marinedepot.com/aquarium...no_series_tarpon_wahoo_marlin_information.asp

I want to keep mixed corals and thought (there I go thinking again) I could put those that like lower/moderate flow out of the line of "fire". I really don't want the flow to be directly pointing at any one coral ~ I just wanted to make sure I didn't have any dead spots in my tank. Hoping to do it right the first time and not have to disrupt the tank after it is up and running.

Thoughts?

Thank you for your replies.
