Finally a Tank Big enough for this thread, 200 gallon 48x48

I finally have a tank large enough for this thread. Now that may seem like a weird title but my main display has always been just under the 180 mark, 150 gallons actually, and its always bugged me that my system is big enough 270ish gallons, but my main display wasn't.

Okay so now that, that is over, lets start with the basics, I picked up a used 48x48x20 eurobraced tank today, that I will hopefully get the stand roughed out tomorrow so that I can really start to plan out my twin sumps, as well as the plumbing to integrate this tank into my total system. Now to some this may sound like a major pain to plumb two systems together that are on opposite sides of the room, but for me the benefit is, only one set of controls needed for water change, and ATO, as well as using one larger skimmer. In addition to being able to monitor it all thru one apex, as I work in the oil industry and travel 2/3rds of the year, roughly 2 weeks on, one week off.

Working on uploading some photos right now, as well as some sketchup ideas for a false wall to hide my power heads, as I'm a big time fan of gyre type flow.
 
Teaser pics,

As it's going to be a few weeks until I can get it moved down the two flights of stairs down to my fish room

And a little bit of flow, over kill for the mixed reef I'm going for, but I will likely never have them all on at once, just wanting options and flexibility that the closed loop on my 150 doesn't offer.

Still undecided on my return, looking around 1000 gph in the tank after head losses. Looking for submersible as may do something unconventional with the sump.

Thinking about a shallow sand bed of sea floor special grade and mixing dry rock with live rock to build my reef structure. Since the tank is going to be positioned in the corner I'm thinking a C shaped structure with an island centred in it. Having a peak of the C potentially breaking the surface, all depends on the rocks I can get and how the aesthetics work.

Also leaving the perimeter very open to create gyre type flow as my tangs love it in my other tank, just swimming in place holding one spot in the current. Also the rock work will be elevated so I can create the horizontal gyre as well, under and over the reef structure.

As for lighting I'm going to go led, either radion or hydra 52 or even both, but I would like a central spot light to highlight my rock structure, a potential clam bed in the centre and maybe a mangrove or two on the emergent portion, for this I thought maybe a kessil, but a halide just makes more sense. For the past five years I've only done led on my planted and reef, so input on halide options would be appreciated. Especially as I only run my chiller for 2 months a year right now.
 
A few weeks, quickly turned into a few months as work and life got in the way.

After trying unsuccessfully to wrangle enough people together to get this moved to the basement I made the decision to cut it and re silicon it. Since I had to do all the cleaning and prep work in the garage I figured what the heck, I might as well bevel all the edges. This turned into a great en-devour, as I already had the wet polisher and pads, from doing concrete counter tops, but I really should have chose to do this during the summer, as doing it when snow is on the ground really did suck.

After three days of being damp, and cold and really ****ed off at myself for foolishly thinking this would be easy, it was done. Now would I do this again, maybe, but on a smaller scale, as I even beveled the eurobracing.

A few more weeks passed before I was able to commit the time to the fun game of assembling the tank, the new overflow arrived, as did the new back panel, as the original was chipped and had a really small overflow. Now I've built smaller tanks before and figured this would scale up, boy was I wrong. I now have a strong dislike for silicon, as it makes a mess, and I much more appreciate those who build tanks with excellent silicon work. Mine holds water, but boy is it not pretty. Now with water in it its not bad, but I'm skill considering doing aluminum trim, covering up all the fancy bevels in order to hide my less then stellar silicon work. What follows is the obligatory "mermaid" shot, but probably not the type that most people would hope for.

Now while the silicon cures and the equipment arrives, I sill continued to collect live stock and crammed my poor 40 gallon full. My Durasa clam found it was no longer alone when a ReefRaft order arrived at a local vender and two tear drop palau clams arrived in my tank.

To this were also horded various Acan, Blasto, Torch, Hammer, Zoa and a few others. A trend was developing that this tank indeed was going to be my LPS system, leaving my 150 to be for the SPS critters. Now there are no pictures of my hoarded corals, as I have a few fish that needed a bit extra food to get acclimated and healthy and as a result my frag tank is recovering from a minor hair algae outbreak.

The packages started to arrive from all corners of the globe, in hopes that over the Christmas shut down, I could begin the setup.

After main struggles and a few missed deadlines, it had functional plumbing, functional lights, and it was wet.

Now I haven't said finished as its far from it, but I have circulation, heat and light. I have something that resembles a skimmer, as my Lifereef Skimmer jumped off of my work bench while I was cleaning it, still to be determined if I will trust salvaging it or if I will switch to a MRC MR-3R. I also am needing to hook up my remote deep sand bed, as well as plumb in my 90 gallon refugium bio filter display tank thing.

But since it was essentially operational, I added in some new dry rock, as well as add about 50 lbs of live rock from my other system. After this was added I needed something to keep the system going, so I transferred all my fish out of my holding tank, and boy do they enjoy the change of scenery .

Sargassum Trigger
Niger Trigger
Purple Tang
White tail bristletooth Tang
2 Vlamgii Tangs

and that takes us to today.

Now the tank hasn't been scaped, as I'm still awaiting some branch rock, so its arranged right now just to keep all the live rock exposed to light and to allow flow and hiding spots for the fish. My canary corals, a couple zoas a gold hammer frag and GSP are all doing well so after I scape next week I may start adding in a few more precious gems from the frag tank.
 
Apparently you failed to read the fine print: square tanks don't count! :lolspin:

Well I guess that it is a good thing that I'm finding it too small, so already planning to upgrade to a 48x96, granted that will be a year or two away. As I've decided having storage in the fish room is over rated, If I remove my cabinets I can put in a larger tank
 
Couple questions for you.
What is the glass thickness of this tank?
and do you have any sort of styrofoam under the tank?
I'm actually debating about building my own tank this size.

I'm actually debating about building my own tank this size.

The tank is built out of 1/2" glass, it was built by a custom builder in Edmonton, but since I bought it used, and this builder doesn't have a good reputation, I chose to cut it and redo all the seams. I also replaced the back panel as it had stress cracks radiating from a poorly cut overflow groove.

It is sitting on 1" foam, that I then placed black plastic on top of so that I wouldn't have the white showing thru.

Thanks man. Can't wait to see this build progress.
 
Hi, I was following this thread as I like the tank idea and want to go the same, but in smaller size. Any further update?
 
Well this tank has had its ups and downs, and I'm fairly confident I'm back on the upside of things.

I had a float switch issue twice, as a result this tank flooded my basement and I lost most livestock. I have since replaced my cheap ebay float switches with the shielded ones from Madison Switches and have had no issues. I have also incorporated an optical switch as my high level emergency off unit.

Now that parameters are once again stable, I'm dealing with nutrient issues from the die off, as the tank was pretty neglected for awhile. The fish are fat and healthy but aptasia and cyano along with bubble algae are running rampant.

I've began doing water changes again, started to run bio pellets as well as increased the size of my fuge. And changes abound. life is once again returning to the corals, a red goni that I thought was completely gone is springing back to life. So now I am attempting to combat the Aptasia. I have two filefish, whom ate the aptasia for awhile, but are now interested more in frozen and pellets. I also have a copperband, but well with my rock work there are many other tasty treats to eat other then aptasia. So I have once again turned to Berghia to help me out. The local supplier lost his colony and as a result I was forced to import from the US, so I brought in 60 individuals for myself, and have them growing and breeding in a separate system until I have a large horde that I can unleash upon the Aptasia scourge.

But in the mean time here is a video showing some of my very healthy fish, as that is the very common comment I get when fellow reefers are over... the fish are healthy and well so are the aptasia.

Finally an Update

Finally an Update

So I've sorta let my threads go a bit stale, but the tank is doing really well.

So well in fact that I'm having to upgrade as its getting way to small for my critters.

Over the summer I am gutting half of my fishroom and putting in a large plywood tank. Now I know there are many downers on plywood tanks, but I built a test tank last summer that is showing no signs of issues, as well as I work in the coating industry and have access to coatings and equipment that most hobbyists don't, this should result in a near bomb proof tank, that will be water proofed in minutes, thanks to high pressure plural spray systems.

Now to keep people amused and satisfied until I start that thread, here are a few videos of the current 200ish gallon tank.
