With the background I think the top being covered is more important than the bottom, the live rock and sand will cover most of the bottom.
Shawn that would be great if you are there get me a price for the 1" ID stuff. Man you type fast. I have the exact same background in my 65 gallon reef.

Al your absolutely right about the rock work covering the bare spot per say......I just came from checking the last pour I did and happened to measure the width of the background with the edge cut off as I'm planning to do, and it's about 1/4" short. Not a big deal as you pointed out. I really can't run it clean up to the bottom of the euro bracing anyways, because of the 45's that are installed for structural support and it would go back to your angle theory on the corners of the tank as well. What I'm planning to do here in a bit, after my phone charges is shoot a short video of the tank and progress of the initial (white) epoxy coat pour. In the video I'll point out the area where it will stop due to the 45's and get every ones advice at that point. Hopefully the video will give everyone an idea how far along I am, and hopefully finish all the epoxy work. The worst part is just waiting for it to setup so you can rotate the tank and pour another area. The tank is really starting to get to be a handful rotating and moving it.
On another note, as most are aware; I've been going back and forth between glass and acrylic. I think somewhere in the beginning of the thread I had said that if I opted to use glass it would have to be Starphire (PPG) or Low Iron glass. Some people will try to feed you the line Starphire or Low Iron glass is softer and scratches easier!!!!
That thinking is incorrect. Low Iron or Starphire glass has the same properties and hardness as regular float glass. So through a friendly get together this past Sunday of some friends who also have tanks, my 1 buddy just happen to let out a friend of his has a glass company about 45 minutes away. Needless to say my friend called his friend and I got a price on 3/4" Low Iron glass for the tank.....Under $500.00 for both the front and side viewing panel. I had been quoted locally a $1000.00 just for the front panel. So I've actually decided that the front and left viewing panel will be Low Iron glass. The right viewing panel that will be hidden in the fish room which will also be part of the external wave box will still be acrylic......This is due to the construction idea/process of how the wave box will be built and needs to be drilled. I have drilled tons of glass tanks, but feel acrylic would be better for this application, for several reasons, once the build process begins on that part of the tank. I also don't feel very confident or comfortable doing the wave box without it being support and due to the constant fluctuation of water level in the wave boxes........
PS.....Al I use to type in my earlier working days, and have been timed in excess of 68 wpm....

I will call them at 10 am....That's when they open.....do you know what length your looking for? I seen they had 4' & 6' lengths. I was eying them up thinking what I could use them for/with......

Here's another short video. This just shows the progress so far on the tank progress. As you'll see the initial white coat is all but done, and now it's just down to laying the final coats.....Shouldn't be much longer!!!!!
All in the video where I show the shots from the inside of the tank where the cutouts are leading to the overflow box.....the 45's under the euro bracing won't have the backgound on those areas. I honestly don't think you'll pay much attention to that area once the tank is up and running and stocked.....Hopefully tomorrow I'll have all the white done, and the tank sitting right side up and I will shoot more pics and such, to give a good overall look of it. The white except for the bottom will receive another layer of epoxy, but this time it will all be in black. Everything will be done in black expect for the bottom which will get the final white coat, and then clear on top of it, the rest will be black. I've looked at the blue gel coat, and I'm just not liking it at all. Just way to dark.
Let me know what you guys think!!!!!!

.I'd like to get the torch setup with the long hose by Benzomatic.....just can't stomach the $60.00

Part of the reason I like working on a project is that it's an excuse to buy new tools.
At least going into a project I like to know a ball park figure of what it's going to cost, to see if it's even feasible for me to do. The construction costs are "one time" and once it's done, it's done, but it is the monthly recurring costs that I really try to know in advance. I built a 180G in-wall tank set up about 5 years ago. It was beautiful but ended up being too costly for me to run the heaters, lights, pumps, etc, along with the other routine maintenance. At that time I just couldn't justify it on my income.
It may have been asked earlier, but why did you choose plywood over the other construction methods (acrylic, glass, etc)? It doesn't appear to really be a time or money saver, are there other advantages?

Overall cost to run I haven't figured out, but my 240 costs me rough an extra $100-$150 a month depending time of year, but with this build being a little smarter/wiser on equipment selection. I've never been one to skimp on equipment, but there are more economical ways to run tanks. I've thrown out there in another section the possibility o using small solar panels to even run small items such as my Tunze PH's heaters etc. I was told to expensive and not really feasible, but that still hasn't stopped my searching or believing I can't do such a thing. You have to dream!!!!!
What made me choose a plywood build????:flame: Nah kidding!!!! I've built acrylic tanks, and glass, I've had tanks custom built with Starphire glass whole 9 yards, so it came down to 2 things. What would something comparable like this cost? Bottom line I wouldn't get all that I wanted in a conventional tank. With an acrylic build the issues with scratching!!!! Yes it's lighter, better insulator than glass, but has it's drawbacks. Glass bottom line; way to heavy, bracing becomes and issue, and depending on who's building the coast to coast over flow wasn't an option, and the wave box option was out. Yes I could find a builder to do these, but when you contact the best builders for something custom unique; you'll have to sell your kidney and then some to get the tank. I'm rather picky on equipment and honestly only 3 builders would get my money and that would be James from Envision Acrylics ( the best), AGE, no I don't mean AGA, and Miracles. These IMHO are the best builders in the field. Price out their tanks and you'll understand some of my madness.
Another issue is size of the tank. I didn't want your traditional store bought, production line tank. Rather limiting at times with options. I was after width, and there was no way I could get a tank of this size through the doorways; into the stairwell, down the stairs into the familyroom, so the tank would need to be built on site. Of course you could get a builder to do it on site, but would drive the price up even more.
Basically the finall decision was that the plywood build was a challenge!!!! It's not often you see them, and they are a total expression of the builder. I am able to tailor everything around my build as I choose. You might be trying to reason or rationalize labor; time spent, but when you enjoy all aspects of the hobby the labor doesn't matter, because your getting what you truly want. Might take some time, but it's all personal. Take all the woodworking done so far, all the detailed trim work, light rack, fishroom. These are all things that aren't store bought and makes you utilize all your talents, and pushes yourself to be better or learn!!!
My last build on my 240 was boring. I get bored when everything is store bought and thrown together. I spent over $30k just on the build and equipment. Did I enjoy the last build as much ad this one???? H3ll No!!!!!

Well put, I thought the only reason for plywood was for custom sizes/installations but you also add in the talent and now I see why it's appealing...
I would try it if I had a wall worthy of installing one in.

Sorry Al for taking so long....I had a major brain fart, when we were talking about the hose last night...Guess I lost a few to many brain cells to the epoxy.....I couldn't find them on their website, and I woke up this morning, and got ready to call them and happened to look down on the breakfast bar, right beside my laptop, and low and behold there sat their new catalog, and I opened the book and there set the exact hoses we were talking about, along with the prices.....
Prices are as follow for 1" ID
2' $8.99
3' $9.99
4' $10.89
6' $13.89

A bit of a setback today.....I was rather pleased with the results of the sample test piece I did on the background........
I got bored and curious while I was sitting and waiting for epoxy to setup to rotate and start another area, so I grabbed the drill and holesaw bit, and figured I'd drill the background sample.....I had some reservation about how the background might react being drilled. I was suspecting the bit, might grab the background and tear it instead of cutting it.....Good thing I like to play with things ahead of time, but what I found is that the vinyl background material doesn't bond/stick to the epoxy.....So with that said, once I drilled the sample piece it cut perfectly, but I can take a razor blade and slide it between the coat of epoxy and the background.....The epoxy is intact and not damaged; just I can see and tell, that it doesn't adhere to the vinyl background at all.......Back to the drawing board!!!!!
Ok guys need ideas and all input....Calling all hands on deck!!!!!

Sorry on the poor video....Could be the tv in the background or just behind the sample piece the tank is sitting and could have been echoing off the tank.....At least I'm getting closer to the end of epoxy work.......Just a minor setback!!!!!!

Easy fix.. Just drill/cut a hole in the vinyl background a little larger than the the hole saw. then when you epoxy it in it will seal and you can just drill the hole inside the vinyl hole... Hope that makes sense!
Are you worried at all about water getting into the void between the layers???

Personally I'm not a fan of patterned or fancy backgrounds. I think they look tacky and end up distracting from the things I want the attention to be on, namely the fish, corals, and inverts. I always paint the outside back of my glass or acrylic tanks. I used to do blue but now only do black. Just my preference.

Desertdawg your idea does make perfect sense to me.....I should have thought about something on that line. I know that once the bulkhead holes are drilled I'm going to pour the edges of the exposed edges, so everything is completely sealed......I think I was sort of thinking something like this would possibly happen, that kind of why I had questioned wrapping the back corners of the tank as well due to the possible thought of the 2 materials not actually bonding to each other......I think I might give the techs a call Monday morning and see what they say or what they might suggest, but I think your perfectly right. I just need to determine where my bulkhead holes are going to be located on the back wall to drill the background material.

I'm not a fan of backgrounds as well Ben, and usually I do paint my tanks on the back, but how do you consider the background material distracting when it plays into the image of adding depth? Curious as to how it would distract???

I haven't seen the background you are going to use on a tank in use, in person, but it doesn't seem like it would be distracting (poor choice of words on my part). It is just that the ones that I have seen locally just look so bad and unnatural that I couldn't ever see using them. For the "tape on back" style, if later on you decide you don't like it, you can easily remove it. Yours on the other hand will be pretty permanent. Is there a "plan B" if you epoxy it in and then decide you don't like it?
This tank has a black background and has depth of darkness. Of course, it is 90" front to back to begin with, so it is not a very fair comparison, but it is beautiful.

To achieve this illusion, he has to keep the black acrylic very clean. Is the epoxy surface "scrapable" with an acrylic type scraper?

Ben if you look for 2Quills build over in the Reef forum I think it is, he used the background on 1 of his setups......Honestly I didn't realize it till he pointed it out to me....I was caught up into checking out his tank never paid any attention to the background!!!!!!
