tpallas' 33g SPS Dropoff Tank Build

Introduction

Some of you may know me from my other thread on the nano forum, my 11.4 gallon Mr. Aqua SPS tank. I've been keeping fish since I was 6, and saltwater fish since I was 12. My first job was at my LFS, Marine Care Specialists. Needless to say, I've been hooked ever since.

First and foremost, I am 100% keeping the 11.4 gallon tank, and am very excited to see it grow out into a full-blown SPS nano forest. My original intent was to make this a soft coral tank, but with all the planning and effort going into it, I can't help but make it a SPS tank. Maybe I'll set up a third tank for softies?

But instead of the normal rectangular tank, I am jumping on the dropoff bandwagon. There are some great dropoff tanks starting on RC, so I thought I'd throw in my hat as well. So hopefully my build will be interesting and entertaining, and give me the results I'm looking for.

Design Concept

Here's a Sketchup of my concept:

The idea is to have the tank and stand match my 11.4 gallon tank as a piece of furniture in my living room, and a semi-room divider. This sketchup is very preliminary; I intend to lay out the exact setup in detail before I make my first purchase. I've been working with Adam of Artfully Acrylic who has been working with me for two weeks now to ensure that every exact specification is met. The tank will be rimless 1" cell cast acrylic, 30" deep with a 6" deep coast-to-coast overflow, 18" wide, and 24" wide on the bottom step/12" deep on the top step. In the overflow I'll use a Bean Animal setup to reduce noise to a minimum. There will be two 3/4" returns with Loc-line. The back panels will be black and there will be a 1" lip on the lower back wall to retain sand on the upper step. Adam will also be building the stand for me which will match my 11.4g stand, plank style with an all white interior.

Equipment List

Lighting: I'm a little torn on this. I intentionally made it large enough to accomodate a 24" unit if I opt to go with MH/T5 combo. I'm using a Sol Super Blue on my 11.4g, and I do like the LEDs, but I wonder if I might get better colors from MH/T5. There is also the heat to worry about. Other options might be a Radion or a Vega if the reviews are good.

Skimmer: Bubble King Mini 160. 'Nuff said.

Sump: I plan on going to Jeff at LifeReef to build a custom sump for this. He does amazing work. I'd like to incorporate a small refugium and potentially an area for frags to be lit by a AI Sol Nano. That way I have a place to prop frags in the stand, out of view. All told this should add another 20 gallons water volume to the system.

ATO: Tunze Osmolator.

Controller: I will use an extension box for the Profilux 3 and run a control cable to my tank from the 11.4g stand. This way, I will be able to control both tanks through one controller.

Return Pump: Tunze Recirculation Pump Electronic.

Flow: 2 x Tunze 6055s. I had hoped to use MP10s, but with the 1" thick sides, they're out. So I'll mount the Tunzes on the overflow wall.

Way Ahead

I'm currently finalizing my order with Artfully Acrylic. Build time is looking to be 2 months out so I'll be collecting the equipment in the meantime. The only big equipment choice I have remaining is, what type of lighting to use? I suppose there's as many answers as people.

More to follow.

Cheers!

Bk mini is a huge waste of money, nuff said. Please put your money elsewhere, this tank is going to look fantastic!

I would not worry about heat from mh. Use a fan or two hooked up to a controller and you'll be fine. I've got 2x250w mh and 4x39watt t5s over my 40breeder
 
looks awesome cannot wait to see the end product

Sweet blue prints, I can't wait to see it all come together!

Thanks for the comments! Sticking with the Bubble King (ordered it today acutally) - hey, I like toys! Also ordered all of the Tunze pumps and now I need to sit down and figure out all of all of the various components I will need for the Profilux extension box.

Working with Artfully Acrylic has been absolutely wonderful. I've spent 2 weeks talking through each and every detail of the tank. Build time looks to be about 8 weeks so in the meantime I'll just be doing more planning, collecting equipment, and cooking rock.

For lights, I'm leaning heavily towards the Vega provided they get some good reviews when they come out.
 
This build is still on, just going slowly!

Adam from Artfully Acrylic designed a metal stand:

The stand was just completed and he is working the mahogany-veneered ply which is magnet mounted to the stand. After that, the tank build will progress and we will be ready for the sump build.

Quick poll: do I go doser or calcium reactor on this one?
 
This looks really great! Can't wait to see it develop! You're using acrylic?
And what do you plan to stock it with?
Great Tank!
 
Thanks! That's 1" thick acrylic so as not to require eurobracing. I'm planning on a select few SPS for this one - still making my list!!
 
It's 24" long, 18" wide, 24" deep at the lower step at 12" deep at the short step. I'm also installing some acrylic rods to make it easier to mount rock to to create a dropoff effect.
 
Thanks guys! I'll provide updates as they come....hopefully the tank will be done in the next couple of weeks.
 
Hi mate, was wondering f you could post the dimensions in an image? I'm planning on doing something similar to you, and would love some help! Your tank is amazing!
 
Hey Charlie,

Here are the dimensions on the original drawing I made in sketchup. I was going for a conceptual drawing and not exact dimensions, but you get the idea:

I guess youll have the best of both a shallow reef and a deep reef tank all in 1. Im thinking flow at the bottom will be reduced and you could keep LPS on the bottow and allow them to be super inflated while having SPS on the top tank...simulating a reef crest. It will look neat. nice idea.
