My Dream Tank- 225 Gallon Custom Shallow

Hi all,
I have been following (and envying) your large tanks for years. I have been keeping Reef tanks for almost 13 year now. I started small and worked my way up to a pretty nice 120 at one point. I scaled back for a while, and when I recently moved to Montana I went on hiatus. It has been a little over a year and a half now with no reef :headwalls: I am very happy to tell you all that we purchased a home that we feel like we will be in for quite a while so it is time to jump in again. I have been plotting and planning this in my mind for some time now, and I am super excited that it is finally coming to fruition. Helping me with all of this is Tanner at Crystal Clear Aquatics in Bozeman, Montana.
Tanner is building the tank for us with these dimensions: 88"long x 29.5" wide x 20"deep (rimless). The front and the left side panel will be low-iron glass. We thought that 20" will still look plenty shallow over the distance of over 7 feet across and still give us enough space to do a quasi-bonsai SPS dominant reef. the stand will be a very simple iron stand with a completely open design. I have asked that the stand builder add a leg in the front-middle to match the rear, and also for another bar to run across the floor in the front making it basically a rectangular box of a frame.

The tank will be lit with 3 Kessil a360w. I have done some research on the spread of these lights. My idea is 2 "islands" in the tank. One about 48" wide on the right side, then a 24"ish one on the left. The larger of the 2 islands will have 2 Kessils over it and the 24" island will have 1. I hope that there will be enough light spilling over so as not to have shade in the open areas. I do have a plan to ad another Kessil if the left side looks too dim. The lights will be on a track system above the tank to keep everything looking clean and allow the ability to move the lights if need be. They will be controlled be an Apex Neptune controller.

Instead of having the equipment under the tank we will be routing all plumbing into the wall then through the crawlspace and back up into a closet under the stairs about 10 feet from the display. In the "fish room" we will have a 75 gallon custom sump, 55 gallon refugium, 55 gallon saltwater mixing vat, and all related equipment. All drains will be plumbed into the main drain line of the house and a bunch of planning has been done for emergency drain redundancy to ensure no water will end up on the floor. This will also make water changes a breeze. Thanks, Tanner!

Instead of writing the rest of the equipment list out in story form, here is a list of what I've got so far:

-Apex Neptune Controller
-(3) Kessil a360w
-200# base rock
-Reeflo Hammerhead 5555GPH for the return
-Reef Octopus 5000-SSS with bubble master pump
-(2) Hydor Koralia Evolution
-(2) 300 watt titanium heaters
-Melevs reef RO/DI

I am sure I am forgetting many details. I just wanted to get the build thread started so that I don't have to backtrack too far once it starts moving along. If you have any questions please ask. Or, if you have any advice or comments please feel free to leave those too. I will post more pictures as I have them. Tanner should have the glass in by next week, and the stand should be being built next week as well.

:fish2:
 
Sounds great. I like the idea of having a large dedicated refugium. Im currently using a 60 gallon frag tank 6'x2'x8" as a refugium. It is a thick forest of caulerpra and chaeto and it has really benefited my system.
 
Thanks, jt48! I checked out your inspiring build thread yesterday. I did a bit more reading this morning. Wow! I really like your fuge. I would love for mine to look like that. I know that some people in the past have had problems with caleurpa "going sexual". Do you have any concern over this? I have personally kept it in fuges before without issue.
I did a lot of reading about the "big" tank builders nationally. I had my heart set on a glass cages tank for a long tim, but the reading i did was about 50/50 on both them and Miracles. I am glad that you had your issues satisfactorily resolved, though. I was really excited to find, Tanner, a guy who builds tanks locally out of Crystal Clear Aquatics that would build to my specifications at a very reasonable price.
Thanks for checking in. I hope that you will tag along on this build as it is pretty similar to your setup. Not only in tank design, but also in the remotely located equipment. Wish me luck!!

Thanks and good luck.
Sometimes i do worry about the fuge going sexual but take measures to prevent this by providing 24/7 lighting, frequent pruning, and frequent checks. I have experienced what i believe to be a partial die off where about 10% went sexual. The bad stuff was pulled out and did not notice any negative side effects on live stock.

Its not for everyone, but for me it has helped and i am able to keep an eye on things easily as my job does not take me away from home at all for travel.
 
Sound like an interesting build plan.
Let's see some pictures of the current scenario how it looks before the big change.

You might want to use Sketchup (free) for 3d planning. It takes a little to get used to the software but it might be very helpful.

Here is my build thread in which I started my stand in 3d as well.
Very soon I have to incorporate my wifes laundry, lol, or at least parts of it.

Thanks psxerholic. I am familiar with, but haven't used sketchup much. Tanner met me out here at my house this afternoon. We finalized all of the measurements. The toughest part is going into the wall behind the tank with the drains and returns. We used a hole saw to drill up into the wall from the crawlspace so that we could see up into the wall. We have about 15"x 4" to work with so we should be fine there. Once it comes through the floor into the crawl space we have free range to go where ever we want in the direction of the closet. It is really roomy in the crawl space about 5'6" space between the floor joists. Once we bring it back up into the closet we should have more than enough room for plumbing the refugium and the sump. Oh yes, the saltwater mixing setup will also be in the crawls space.
 
Here are some pics of the spaces as per psxerholic's request

Space where display will go. The stand will be 38" tall making the top of the tank roughly 60" from the floor. It will be centered on the wall with 18" on either side.

The drain and return plumbing will be run in the wall in the space between the outlet and the heater return.

This is the closet that will be the fish room. All the boxes are reef related goodies =)

A photo of the crawlspace. on the other side of all that ductwork is where the display will be (about 15 feet away).

Ladder back up to the fish room closet. the drain you see in the background is the drain we will tap into for the system drains.

Interesting plans. Thx for the pictures. Keep the progress posted.
Will be a nice build!

What will you use for sealing the penetrations in the walls?
 
Hey, Looks great.
Now get it out for sandblasting and paint it, lol.

By the way, beeing a mechanical engineer for steel structures etc. in the O&G business, I really would recommend to add a center support on the bottom in the middle to avoid bowing due to the forces coming from the top frame.
A simple piece just bolted in between will do the job. There is only a little bit of tensile force required to keep things thing literally together therefore a simple bolted straight piece of steel will do the job.

Keep up the good work and progress.
 
Which direction? Front to back or side to side? I really feel like this stand is overbuilt for the weight distribution. It is also all 2" angle iron. Tank is very wide and shallow for it's length. I really do appreciate the input, and I will ask Tanner how he feels about it.
 
I like the idea of a shallow tank and how you're going about the planning. The only thing that has me concerned is that register on the wall behind the tank stand. Is that the return for your HVAC? Or is it a transfer vent to/from another space in the house? Might be something you don't want to block.

Subscribed and following along :)
 
Is it going to be blocked by the stand? I mean will the stand be enclosed? If so, that will wreak havoc on your system. It would be a good idea to relocate it. Then you can use that penetration to route your plumbing. Looking at the pics, the air handler is in the crawl space below. The return being blocked from good flow is going to not only put a strain on the HVAC, but also diminish it's effectiveness. Relocating it looks like a pretty easy task considering what things look like in the pics.

Basically in the middle a shorter piece from front to back. Simply bolted at the end with one hole on each side to avoid a bow effect due to the forces distributed from the top frame down.

It is very robust but this detail is concerning to me.
By the way you can do this with home improvement stuff by yourself. No welding required.

If a hardwood or plywood baseboard will be mounted in the bottom and you drill and srew that along the back and front could do the job.

Talk with your builder. The forces downwards can go toward both directions, worse case into the direction that cause a bow.
