mag 7 or 9.5?

[osueyedoc]

quick question,
i'm finishing up my planned sump/refugium setup (thanks to foxthorn and many others!). I'm purchasing a Nautilus Te and had decided on a mag 700 due to all the good things i'd heard about it. But then i saw some posts saying the 700's performance dropped off much quicker than the 950's as you increase the head. my sump will only be about 4' below my tank. i plan on using the schematic below, including the t-fitting over to the refugium. should i buy the 950 instead?

I agree go with the mag 9.5
I had a mag 7 on my sump/fuge for my 50g reef but recently switched to a mag 9.5 and have not regretted it

Go with the 9.5, so if you miught upgrade too a bigger tank, 90, 100, the mag 9.5 would still good.
Hondo what did you do with the mag 7?

I used the mag 7 for the sump I put on my 37g reef.

thanks guys....i was kind of thinking along the same lines.
another question:
what are your opinions on the overall design of this sump/refugium? my other idea for a sump/fuge would be instead of buying a 30L to use in this plan, i could use a 29g i already own as a sump, and buy a separate 10g or bigger for the refugium. what are the pros and cons of each design?

pro: easier to fit inside a stand. more versitile.
con: cost of drilling glass to connect them, or the cost of an overflow.

Hey man. I'm not far away, in Pickerington. I originally went with a Mag 9.5 in my 125. I have it running the refugium, cross current protein skimmer and a spraybar return. It was pretty maxxed out. I ended up going up to a mag 12, and I'm glad I did. I have some spare pressure now, even though I've added a calcium reactor (small flow) in addition to the others. I'd go with a 9.5 minimum just to make sure you have enough flow.

I'm a little confused. Are you talking a mag 7 to run your skimmer or mag 9.5 for your skimmer or mag 7 or 9.5 as your return. The mag 7 for your skimmer will have no head height and Kent recommends the mag 7 for the nautilus te. It works great. By the way, the nautilus te's output will not work with your design to output into a baffle area. The TE outflows right next to the riser tube and will be adjusted to get the right air/water mix. If you want to have your skimmer output to another area you will need a different skimmer than the TE.
