how many sea swirls and what size?

browning_boy20 · 03/31/2013, 06:34 PM

I am in the process of building my 350 tank and need some advice on the sea swirls. My tank is 96x33x25 and I was curious as to what size I need and how many? I am going to run my return from the sump through them via a Reef Flo super dart gold pump. Any advice is appreciated.

I run four 3/4" Seaswirls with a single Iwaki 70 pump (1800gph). It was decent flow wide open throttle but I wanted more... I put 4 penductors on the seaswirls and had to turn the output of the Iwaki down about 40% due to crazy flow through my display. I have probably 5 times more flow now AND had to turn the pump down 40% as mentioned. If I were you, I'd run five or six 1" Seaswirls with penductors off of a pump that can move 2500-3000gph. You will have more flow than you need!

with the super dart, you can use 2 -1" seaswirls with the head loss, I run 2-1"
with a Hammerhead pump on my 300,12' head loss.

I also forgot to mention this will be a bare bottom fowlr. This may be a stupid question but if you have 4 sea swirls and now have them turned down 40% could you make do with 3 and turn it up some? I am new to this so I am still learning.

Is that all the flow you have for your tank?

I would think that would work also. Penductors increase back pressure on the lines and fittings, so they will exploit any poor plumbing (insufficient glue, pipe work, etc.). I had to turn the output down because the flow was moving my sand around too much on the bottom of the tank. I just turned down the valve until I found the sweet spot.

Oh ok. I see now.

My tank is 96x48x24" tall. I have two 1" Seaswirls at one end of the tank fed by my Reeflo Hammerhead return pump. On the opposite end I have a pair of Tunze 6205's and a Koralia 1400.

I would say two in your case. Any more and you will disapate the flow too much.
