What size icecap gyre for a 50g cube?

Daniel@R2R · Apr 30, 2021

What size icecap gyre would you recommend for a 50g cube? If I get one that's too big, can I run it on lower settings? I'm thinking about getting this to add flow to my cube. I'm currently running an MP40 on the back wall and an MP10 on the side... I'm thinking I'd put this on the other side. Am I crazy?

I have a 2k and 4k running on opposite ends of my 75g tank. I think the 4k is too large and kind of creates too much flow around the tank for my euphyllia and other LPS corals. I think I would prefer to have two 2k gyres.

The minimum you can run the 4k gyres is at 25%, so this is still quite a good push of water. I think you might want to look at a 2k for the 50g cube. I saw a guy run 2 gyres on a cube...one horizontal across the top, and the other diagonal on the one of the sides. He liked that flow for his SPS coral.

1K would be fine in a 50g cube IMO
but 2K tops.

i have 2x 2k's running same end on my peninsula, 3' setup. i have them cranked way down now....the area closer to the two pumps make it very hard to place corals in the area. im limited to zoas this close to the pumps.

Are you planning to run all three together? If you put a 2K on constant flow in the arrangement you described, and set the MP10 and MP40 to differing pulse modes, you could create some insane turbulence. Your SPS would probably love you forever. Softies might complain a bit. Of course you'll have a blast tweaking your placement and flow.

That's the plan! I'm thinking that having that kind of random flow from those 3 sides would be awesome. At least that's the hope!
