Hi,

i want build a pond of 6' X 4' X 2'. Someone say me i can build only 3/4plywood, Is that enough solid mainly the corners and the bottom if it's only screw plywood in plywood
 
I've seen people use only 3/4" plywood - 1 main box with 1 layer external bracing. Though you would definitely want to use screws AND wood glue, not just screws. However, for piece of mind I would recommend using 2x4's and/or 2x6's as bracing, that's how I build mine. It's not as pretty, but you can still wrap that with a thinner sanded plywood veneer or build it into a wall.

Here's a pic of my plywood tank after bracing was installedIMG_1207.JPG

and here's a link to the youtube video I used as a guideline, this guy has a lot of great DIY videos
 
Thanks, it's definitely more than it needs, but it's always better to go overboard and have piece of mind. I should also add that after a viewing panel is installed you need to add bracing on top too.

I used Pond Shield by Pond Armor. It's a two part epoxy that you paint on. It's basically a very thick paint, very easy to use. I used 3 coats but probably could've gotten away with 2. again, better safe than sorry

I'm still contemplating trying a pond liner with an acrylic viewing window using 3M 5200 and SS bolts for my first tank.

Im also leaning towards your approach with pond shield and then siliconing a viewing glass windows in place. Did you fiberglass your seams? I was wondering if I could get away with only screwing and gluing my corner pieces together and just use a few extra coats of pond shield to make up for it. I have zero experience with cloth.

I don't have any experience with pond liner or acrylic to wood interfacing but I know people on here have used them so I'm sure you could find more on them.

I did use fiberglass cloth on the seams. It was only my second time ever using cloth like this, and the first was on a roof repair, so I'm no expert by any means. It's a little annoying to do, but totally doable for a first timer. The key is really just putting a ton of pond shield underneath and a ton of pond shield over it. I would strongly recommend using something extra on the corners. If you ever have leaks, it will definitely be the corners or the plumbing, and even the slightest little crack will cause a big problem. Plus, without the cloth the pond shield on the corners will crack when the tank flexes from being moved or from big water changes. So I would definitely use it, though I think if you go on Pond Armor's website they have vidoes showing a few other options for the corners.
