After spending a few months reading everyone's posts about their projects I have finally decided to build a practice plywood tank. This tank is only for me to get a general idea of what I am doing, so when I build the monster tank(hopefully later this summer), I will have more confidence in what I am doing.
For my materials, I have:
One sheet of 4x8 plywood at 3/4in thick $21
2 tubes of silicone (GEI window and door) $7 (ish, don't have the receipt)
Caulk Gun $2
Miniroll kit $5
3/4 in Screws $7 (although I didn't even use 10% of the box)
36 in x 18 in 3/8 thick glass $48
1.5 Quart kit of Pond Shield $80 (+ $10 shipping)
Fiberglass cloth $6
That puts my current total at about $186.

The dimensions of the inside of the tank are 45 1/2in x 16 1/2 in x 24in (overflow holes were drilled at 20 in)

I placed the tank right side up, so the floor (which is/should be flat) would ensure the bottom ends would be at the same level for the base to be drilled on to.

I convinced my wife to help me out. We flipped the tank over, and placed the base on top. Then Brittany proceeded to drill the holes while I followed behind and screwed in the screws.

I was unaware that it would take a grand total of two weeks for the Pond Shield to arrive, but it did three days ago. I waited until my wife and I both had a free day, then began painting. She mixed it(drill died half way through mixing, so we (she) finished by hand.

Picture of me struggling with the fiberglass that I had to soak in Pond Shield, then place at all the corners of the tank. Unfortunately (or fortunately depending) there was only the two of us, so once both of our gloved hands had Pond Shield on them, the camera was off limits.

Me carefully placing the fiberglass in the corner of the tank.

Done painting, and two more pictures of the same topic. If you look in the back you can see the three holes I drilled for the overflow.

Currently we are waiting for the pond shield to completely dry(giving it another good day or so), then we are going to go over a few spots with a small amount of silicone and put the window in.

I think the total is at alittle under 90 gallons full, but the water level will be about four inches lower.

Because it was so messy and frustrating to deal with the pond shield-soaked fiberglass, I had another thought. Suggestions and comments welcome. Why not paint all the wood with pond shield before assembling it. Then after it's screwed/bolted into place, seal the corners with silicone like you would a glass tank? The only downside I can think of is that the silicone may not adhere to the pondshield that well.
 
well, so far so good?

No frame, so the wood screws can hold the weight of all that water?
If you keep taking such good photos you are going to end up with a very good "How-To" topic here that may give all us guys some ideas for our own tanks in the future.

Got any ideas on how you are going to dress up the outsides when finished?
 
The screws "should" be able to hold the weight of the water. We will be filling this one outside just to be sure.
As for dressing up the outside of it, we are looking at framing both the edges, and the glass pane with a coloured molding, then painting the plywood in between the molding a contrasting colour. Haven't picked out the colours yet though.
 
Will do. I'm placing another order of Pond Shield today, there are several areas that was absorbed by the wood to a point that makes me nervous. Any other suggestions?

Never worked with that product before, but if its anything like paint, stain, or poly the wood will obsorb it differently depending on the area of the wood.
 
Well in places that I am pleased with, the Pond Shield is smooth. But there are places that I can feel the wood's texture and I want to put a second coat over those spots.
 
Ya, I "plan" to use the middle hole as a return. Cross brace was also something I intended, but I'm not sure I understand what you mean by "euro bracing"?
 
i stole this from something off google

Standard Bracing - Small tanks are braced sufficiently by the acrylic extruded top & bottom moulds. Large tanks require glass bracing for strength. Standard glass bracing is characterized by a narrow glass strip that runs around the top entire top perimeter of the tank, as well as a center glass brace the runs front to back.

Staggered Bracing - This bracing style is beneficial when trying to optimize light penetration from your lighting. The bracing & metal halide bulbs are off set from each other. For example: a 6’ tank will have the narrow perimeter bracing as well as 2 or 3 ‘front to back’ braces.

Euro Bracing – Euro bracing is an approx. 3” wide strip of glass that runs all around the perimeter of the tank. It gives you complete & free access to the inside of your tank without any cross braces. This is also a favored option for those optimizing on the light penetration into their tank. This bracing can also be polished for a very refined look. In very large tank applications, euro bracing is tempered.

No Bracing At All - Depending on the tank size and configuration, we can construct tanks with no bracing at all. These tanks will be made with thicker glass and possibly tempered depending on the situation.

Return Lines in Bracing – For independent return lines that are up and out of the way, we can drill holes in the braces. This is also a great way to get more flow in the tank without a lot of messy looking power head pumps.

Starphire Bracing – For no hindrance of light penetration, there is the option of using starphire glass for the tank cross bracing.
