I'm thinking about going with the nuvo black 30l and plumbing an overflow box to the back. And then I can run a much more powerful return pump, and/or mount mp10s to the rear wall.
I think 2 mp10s on the back wall is overkill IMHO. It’s only like 12 inches or so to the front glass.
Of course it’s all up to you, but I would like to see you use the stock pump and spinstreams, and just a simple non controllable tunze for $50 places on the back wall, in a corner, aimed to the front center.
You will be surprised how much good, random flow there is.
The spinstreams will continuously break up the flow from the tunze.
Then you will have a lot of cash to spend on more important things like corals!
If you are doing primarily softies and zoas, what I recommended is PLENTY.
I love the tank! Good luck with yours and I would be happy to offer up any advice from what I have learned.
