Flow for 120
 

Right now in my 55 I have 2 koralia 1050's and a koralia 2 (approx 700gph).
What would you say would be good flow for a 120? I was thinking about getting a magnum 7. Would that be too much flow. The return pump would probably only be about 800gph after head loss.

I have 7000 ish gph in my 120

Wow that seems like a lot.
I thnk a mag 7 is 2600 gph + 2x1050 + 800= roughly 4500 gph total so far.

thats gonna depend on what you plan on keeping as far as corals go....and if you want your sand, if your running it, to stay put........ a good general rule is....softies and LPS, between 20- 40 times the tank volume and if you get into SPS higher then that.....I have about 10000 gph of turnover in my 110g....just an FYI, the magnum koralias are the size of a football:mrgreen:....if its within your budget, look at a vortech MP40 of one of the bigger tunzes

I have a 120g and I have roughly 6500GPH in mine. Its a mixed reef with SPS and soft corals.

I'm not sure I can handle a 500 dollar pump, a football I can deal with :biggrin:
I'd probably try and hide it behind a rock.
Ill be starting with LPS only, and moving later on to some SPS.

My main flow pump was from ebay. works well :) cost $50 for something that pushes 3200gph. I have 2 Koralias in there along with the return pump which is 1500GPH.

Thanks for the responses.

Jet jumper- do you know what type of pump that was?

I got the magnetic version though.

Sorry I got 2 for $60 after shipping I believe it was. 1 is in my frag system.

Those look pretty bad ass! I may have to look in to getting a couple, thanks for the link.
