180 Gallon Reef Build - Diary of a Set-up By Giancarlo Podio Starting a new tank is always an exciting challenge full of decisions and surprises along the way and I've always found it useful to look into other people's tank builds to get ideas from. Here I will try to document as best I can my latest tank build. Xmas 2006 - My xmas present:
All-Glass 180g Reef Ready tank with oak
stained pine stand There was one condition however... it is an "upgrade" not an
"addition"... :-) It will be replacing my very overgrown 40g Oceanic Stretch

06/2007 January 2007 - Deciding where, what, how and when... I've always wanted an open top "look-down" reef of some kind so my first decision is to keep the tank open and build a hanging light fixture. A little too tall to be a real look-down tank but I suppose that also depends how tall you are... I'll provide a stool for the shorties :-) Lighting: My initial thought is to have a 400W MH in the center and a 250W MH bulb on either side, supplemented by two 110W VHO Actinics. My current 40g has a 400W 20K MH and 110W PC Actinics so it will be a step down in intensity which is fine as most of my coraline has gone from the intense lighting. Sump: This was the hardest decision so far... I debated over many tank sizes but I could never surpass the fear of not being able to remove the sump from the stand without lifting the main tank or some other method requiring a circular saw... the only thing I came up with was 14g Rubbermaid Roughneck totes, I have used these for years for maintenance and water storage and trust (hope) they are safe for long term use. I purchased 3 of them and connected them in series using bulkheads for easy removal in the future. One will house the skimmer and drain pipes from the display which will flow into the center tub where the return pumps and heaters are located. On the other side of the center tub will be the refugium tub, here water will flow much slower into the refugium and directly into the return tub, bypassing the skimmer tub. Filtration: Typical Berlin methodology... live rock for biological filtration, skimmer and refugium. Circulation: I'm thinking about 2000GPH between tank and sump and an additional 2000GPH in the main tank by way of Seio/Tunze pumps. An additional 5 gallon surge device will be used to create a stronger surge in the display. Painting the background: Not wanting to mess with stick on backgrounds
and such, I decided to paint the background. I used gloss black oil based
"Rust-oleum" branded paint and rolled it on with a small sponge roller:

The tank came with standpipes and bulkheads but I had a horrible time trying to get a
good seal around the barbed bulkheads on the drain side. These bulkheads are moulded in
two halves and fused together, leaving a visible line from the mould which isn't flush
with the rest of the plastic. I tried it all, I shaved off what I could, heated the hoses
and clamped them tightly without success. After wasting too much time with this I threw
the bulkheads on the lathe, cut the barbs off and converted them to a female slip fitting
on both sides. Plumbing with PVC from there on was very easy and fast. Here's what it
looks like so far:
I used 2" spaflex to connect the skimmer tote to the return tote and 1"
spaflex to connect the refugium tote to the return tote. I didn't have bulkheads so I used
the gray PVC fittings from the electrical supply section as these have threads that are
not tapered and will tighten down all the way. A regular 2" seal used for flushing
systems in toilets made the ideal seal for the DIY bulkheads. It worked better than I
thought it would.
The skimmer chosen is the Octopus NW200 which is a needle wheel venturi driven skimmer.
It is relatively new on the market and has been getting some good reviews along with a
growing number of modifications people have posted to improve it's performance. Fitting it
in the sump was no problem and I have about an inch to spare on top which is just enough
to remove the lid when needed.
The one "problem" that was evident before running this skimmer was an obvious
bottleneck in the elbow used to connect the pump to the skimmer. These are all metric
sizes and it was easier to modify the existing elbow rather than replace it. Luckily a
regular drum sander attachment that came with my Dremmel tool was the perfect diameter, it
takes some patience as it quickly clogs up with plastic shavings but eventually it made it
through without any problems. Here's a picture of the original sized fitting and the
modified one:
February 2007 - The Canopy I decided to build my own canopy rather than use pendants. The canopy will be slightly
smaller than the tank so that hanging it a few inches above the tank will leave sufficient
room to view the entire tank from above. I'll figure most things out as I go but I need it
to be light and strong at the same time so rather than using solid sheets of wood I'll
frame it out and panel it using plywood... After a few schetches I decided on the look and
started to cut and route all the pieces I need...
Once I had all the pieces cut it was like putting a lego kit together... I glued and
stapled the frame first and then glued and nailed the panels in the frame:
Before staining and sealing I need to test fit the reflectors, glue some pieces here
and there that will support he reflectors off the wood itself and any other modifications
I need to make for cabling, moonlighting and hanging hardware. March 2007 - Time to get wet... I ordered 100lb of live rock from Fiji, it's the "bio rock" which seems to be
harvested from deeper waters than the rock I'm used to seeing. It was nice to work with as
it really didn't need much cleaning at all, there were minimal number of black sponges and
that was about it, a good rinse in a very low salinity water flushed out most of the silt
and mud on the rock and it was ready to go in the tank.
I tend to prefer the "mound" look over the more common "reef wall",
this is why I only ordered 100lb of rock initially, there's another 50lb in the existing
tank and I figure I'll add another 50lb or so to the refugium. As much as 100lb of live
rock hurts the wallet, it really doesn't make much of an impact in this size tank...
I plan on leaving the tank mature for a month now before moving anything over to it.
This will give me time to play with the rock arrangement, finish the lighting and install
the rest of the pumps. Sump update Small cracks formed just above the 2" bulkheads when I tried filling the sump to
the very top. The problem was the bulkheads being too close to the fold in the plastic
that circles each tote. I replaced the two tubs on the right and lowered the bulkheads by
about an inch, this allows the totes to bow out when full without problems. Also T'd off
the MAG18 return pump to both returns, this seems to be the best balance between noise,
splashing and circulation.
Skimmer seems to be working too, this is about 3 days worth of skimmate with 100lb of
live rock sitting in the tank.
April 2007 - Need a light! Been wasting a lot of time on minor details, I really need to push for the finish line
and get this canopy completed!
Stained and sealed Moonlights I decided to paint the inside black to avoid extra reflections when looking into the tank from above. The moonlights are 4" cold cathode lights commonly used to jazz up computer cases and such, they put out a lot more light than LEDs and in a flood light fashion compared to spot lighting. For the time being it's two UV and two blue tubes which can be controlled independantly.
Installed reflectors and tidied up the wiring...
And finally...
June 2007 - Time to move the corals Well the tank has been "resting" for another month while I treat the 40g hex for flatworms. Now that they are all gone it's time to move things over. The move took a little longer than expected, 3 evenings in all and luckily only one of
the large colonies was damaged (I dropped it on the tiled floor...). I moved the rocks
around a bit, most of them are actually in the fuge now. I'm liking the open space though!
