Hi Everyone,

Like many of you who spend time in the DIY section; I get as much enjoyment out of designing and building fish related projects as I do out of the fish themselves. This time around, I have decided to build my own stand, canopy, and sump. I looked around at all sorts of design ideas, and have put together a design that should be simple to build, be solid, and look nice enough to keep in the living room.

The design for the stand is simple; I liken it to an Oreo cookie. 2x4s around the top and bottom, supported by board and ply in the middle with some inside 2x4s for extra bracing. It is very similar to what you get when you order an unfinished wood stand from a LFS. I basically just reverse engineered one, and am adapting and scaling it to my needs.

Given that 6x2x2 is a popular size, I thought that if my build goes well, others who enjoy DIY projects may also want to give it a try. For those who want to build their own, I will post the exact specs for the build including the list of lumber that I buy, the costs, and the cuts that I make.

I have used Google Sketchup to design each of the components for the build. Everything is built exactly to scale, so that all I have to do is measure the pieces on the model, and then cut to those dimensions in real life. There will likely be some building material irregularities, so I will take that into account when making the actual cuts. IE: ¾ plywood is often 0.71 inches.

Here are some overview pictures-

Here is a closer view of the sump:

The sump is a combination refugium and wet-dry filter. I started a design thread for the sump a while back that had some very interesting discussion. Here is the link to the thread: -Feedback on FW Refugium / WD Sump combo design. Some of the details are a little different, but the design concept is still the same. Basically, I will stuff it full of plants and light it. Until I have room for an additional tank, the refugium portion of the sump will also be housing the plecos who have developed a taste for the fire eels. For this reason, I am building the sump with the largest possible footprint. I am still working on deciding what I want to use for a base tank. I have found a 60x18 acrylic, but bonding in the baffles could be a bit tricky if it isn't perfectly square. I am also considering looking into the cost of buying the glass, and building it myself. We have a family friend who owns a glass shop, so I will post updates as I get more information.

The tank has been ordered, and will be ready for pick-up Monday. Last night I wrote up the shopping list for lumber. I will clean it up for posting a little later along with some other details.

looks nice, love the american eagle model lol

LOL, thanks. I made him in my own image. :grinno:

He is there as part of the template by default when you start a new design, and I actually only left him in there for perspective. Without anything to compare against, it was difficult to tell how big it was going to look.
 
Here is the cut guide and shopping list. I'm sure there will be some changes as things move forward. I will update it as necessary. This should take care of all of the structural components. I haven't thought about trim yet. I figured I would get the structure done before worrying about that. Plus, I may have some scrap that I can reuse, and I don't want to think that hard about it or get ahead of myself.

I haven't finalized the 2x4 shopping list because there are so many different lengths available, and I will be looking for quality wood grain for the pieces that show. I may have to cherry pick different lengths to get the pieces I want. Given the relatively low cost of 2x4s, I don't think this should be too big a deal.

From my pre-shopping at Lowes, it looks like the 2x4s are douglas fir, the solid wood boards are pine, and the plywood comes in several flavors such a birch, and I thought I saw pine. As I recall, I don't think the pine ply had a nice finish. I'm a little concerned about how each type of wood will take stain. They are all fairly similar in color tone... but it was a similar situation last time I stained a stand, and it was a nightmare. Although, I don't know what the types of wood were because it was purchased and not DIY.

If anyone is knowledgeable about how the different woods take stains, please let me know. I would prefer to build from the same type of wood, but I haven't found the wood grain quality I am looking for in pine for each component yet. Also, I know that douglas fir is a coniferous tree, and pine is a sort of generic name for various types of coniferous trees... so I'm not sure if I'm splitting hairs here for nothing. So, if anyone has some feedback on the different types of wood, I would appreciate it.

How are you going to get that huge sump into the cabinet area? Are you going to to put that in last before the support brace goes in?

??? And how would you ever get it out if needed?

Looks good, I am looking forward to seeing actual pics

LOL, me too. I will pick up the tank Monday. This weekend I should be able to start construction on the stand. So, there should be some pics by the end of the weekend.

Both of the rear 2x4s will be removable. The compression from the tank and water alone will hold them there, but I will use a few screws on them too. The sump will get angled in and supports attached before the stand goes against the wall.

If I have to get it out, I will have to drain the tank and pull the stand away from the wall. I will definitely water test it for a while first. I don't think this is a particularly uncommon situation when it comes to setups. My current discus tank sump only fits in through the back, and I haven't had any issues with it (knock on wood). The key is to have enough access to be able to completely service everything in the sump without needing to remove it. I should only need to get it out if it fails, not on any sort of regular basis.
 
If you have hardwood floors you can ad a bunch of sliders to the bottom of your stand where you can slide the tank away from the wall to service you sump. I did that to my 100gal and it works great.

No hardwood floors here... just good old fashioned cheap apartment carpet. I would be really nervous about water damage on hardwood floors. Not that carpet is easy to deal with for a spill, but at least you can pull it up and use a fan. If hardwood gets wet, it could be game over.

Good idea though as long as it doesn't slosh when you slide it out. ;-)
