Koralia Setup for a 75g sps tank

[steven11]

So here is how it goes. I have a 75 with a mag 9.5 return. I am not able to do a closed loop or anything of that sorts. So i am stuck with power heads. My question is how many and what size? For example, two K4's or four K2's or maybe three K3's. Any advice?

steven just an example in my 40b I have 3 k1s one in each corner and a seio 620 in the center and one k1 facing down in the back of tank hiddin behind rocks and get very good flow. I think 3 k3s would be great JMO

In your length of tank you would get good flow from 2 K4s. With how you have your return set-up this would probably be your best bet. You could have one on each end of your tank, then position them so they aren't directing flow right at each other.

I'd say try 2 K4s. If you want more after that add a K3.

PS - Shouldn't you be working?

K4 move alot of water in 75 and will move alot of sand if not careful.
