Lots of good input - seems like flow keeps coming up in addition to cleaning.

I've got the urge to do a peninsula in the future too but pausing at getting one that is too long due to flow considerations. The ideas on alternating flow seem great, has anyone used a wave box successfully in a peninsula and what are your thoughts on that helping with creating sufficient flow?

Presently in the design and build stage of my 48x30x17 lagoon peninsula.

For my 48" I don't think flow would be too much of a problem. But I watched the ReefBum videos with his recent peninsula and to achieve the flow he needed, the return pressure was so high that the fish are all blown to the far end of the tank where the water bounces off the the glass and allows them to have some stability.

He may have changed the plumbing by now and corrected it, but it was very apparent there was an issue in the video I saw. So the struggle is real.

Anyway, I anticipate needing a few powerheads at the far end to circulate water back.

As has already been said, getting good flow at the other end of the tank is key. You can see what I did on my 400g peninsula below. Routed returns to other side of the tank, plus added a closed loop as well.

I can (and am) write (ing) a book on the 99 things I thought I planned but didn't with my new peninsula.

Flow is number one by a mile.

Go 48" wide if you can. You will never regret this.

If you aren't going to have a fish room to put everything in, we have a LOT to discuss about the stand configuration.

Enjoy cleaning glass because it's a daily chore.

I absolutely love my peninsula but it has serious challenges I never planned for.

I have a newly setup Red Sea 650 peninsula and it is fairly large, like everyone else has said flow is the biggest problem. I have a Red Sea gyre on the far end and it easily solved the flow issue. I have two MP60’s & two MP40’s on the overflow side and that still wasn’t enough to reach the far end. I built a light mount out of 1515 extrusion for my Kessils and I just ran the gyre cord along the mount.

The flow comments are kind of blowing my mind. My low flow "problem" area is actually on the drain side below the returns; not on the far side of the tank.
This is my problem area as well - exactly the same spot...

I have Gyre pumps at each end. They were pushing the water to the middle. Since the return and overflow are at the same end I wasn't satisfied with surface skimming. I used flex lines under the hood from the return to the opposite end of the tank. That let the surface get pushed continually toward the overflow.

I'm Starting my Dream build with a Peninsula 7225 from WaterBox, (it's was just delivered) for the feeling you get of immersion there is nothing better, no black background, the expansion of two sides for corals, (stocking it with your priced frags is half the fun) I saw them and fell in love. I can't wait to get started.
I started my Waterbox 7225 on May 3rd. It's a great tank.

Here's a challenge I had which I haven't seen really mentioned yet, albeit a nice challenge: scaping

You want to be sure the tank is wide enough that you get good aesthetic scape and dimension on both sides with enough spots for corals, AND enough clearance to clean the glass without bumping into rocks.

My tank is over a year old, and I still find myself playing with the aquascape!

Following as my new tank is being built. It is a 480 gallon 96x48x24 peninsula. One of things that is going to be a struggle is flow. I think I have a plan though. I am going to have return nozzles coming out of the braces on each side. So 16 nozzles on two different pumps. Plan to have two MP60s on the back end towards the bottoms.

I was totally convinced I was getting a large peninsula & I was planning on placing it to divide the 2 living rooms. However, as I did research online & looked at tons of pictures I realized the ability to see thru to the other side was very distracting. With doors & windows on one side & a wall of patio doors on the other I worried it would take away from the enjoyment of viewing the fish.

Tank width and having to leave space on both sides of the aquascaping can make the rockwork a bit 2 dimensional. access to both side is a big plus. it can take more lighting if lights are moved to the sides and angled to light up the aquascaping better. viewing height on both sides need to be considered to determine how tall the stand should be.

That is going to be a great tank. You might plan for at least one other mp60. I have 3 mp60s on the overflow end in a 72x40wx32h tank and it is barely enough, and you have to push another 2ft. Then again, I don't know what your 2 return pumps will be pushing in the 16 nozzles...
