Questions about a future plywood build.

Honestly I can not exactly remember how many coatings I did. I guess at least 3, and more on the critical parts like corners. In the corners you normally want to have 2 or 3 coatings with fiberglass mats before you start coating everything.

Great! Thanks for all information! Will Probably start the build in Oct/Nov

12mm glas should be fine. The standard for glas tanks that size is also 12mm. You just need proper cross bracing.
I would not use pond amor. I have too often heard of it failing. In most cases it started to develop bubbles. I would only use aqurium safe epoxy. The best in my opinion is Bredderman.

Hello, I live in Italy and I used PondShield in the past. It is very good but it's price has gone up a lot, so I'd rather buy ia product from Germany (being eu-patriotic ). Do you have experience with this product? Does acetic silicone (like dowsil 881, saratoga aquarium silicone) stick to it, like it sticks to PondShield? I asked the company but they advised me to ask the silicone brand about it. Which type did you use or would you use for a plywood-bottom aquarium: thelow viscosity or the medium viscosity version?
Thanks.

I've never tried it in combination with silicone, so I have no experience with it.

Viscosity isn't that important for working directly on wood, but it does affect the application of subsequent layers (e.g., epoxy resin on epoxy resin). I personally preferred the higher viscosity, although the lower viscosity version produced a smoother finish (fewer bumps and bubbles).

Thanks,

so what kind of sealant have you used to install glass windows in epoxy-waterproofed plywood aquariums?

Thanks again.

P.S. About viscosity: PondShield suggests to thin the first layer with alcohol in order to let it penetrate deeply into the wood and use the normal viscosity epoxy for every subsequent layer.

Good question. I hadn't even thought of that while typing my answer. Of course, I glued the glass in place with regular silicone. If I remember correctly, it wasn't even special aquarium silicone, but just an acetic-cured silicone with no additives from the hardware store. I just can't find the pictures anymore.
