Indoor plywood pond

  • We are currently upgrading MFK. thanks! -neo
I'm still thinking of going with bare plywood and drylok! Might be the first one to do it on a tank this big.

What do you guys think about using glass from a 55g? It will be up at the top as far as i can get it. Petco is having a $1 a gallon sale so i need to decide if it would be alright. I am guessing the thickness is like 3/8? I'm not sure.

What do you guys think of coating the plywood in concrete and sealing it with drylok?
 
i got one of those $1 a gallon 55 and it was a great buy.
with the concrete isnt there a risk of it breaking while moving the tank since it will only be a thin layer that wont actually stick to the plywood.

just throwing that out there, im not saying it wont work.
 
I would like to see someone use bathroom tile, but I don't know how well the grout would cope with submersion.
 
Use silicone to stick the tiles down and for the grout. If you tape around the edge of the tiles you will limit the amount of cleanup from grouting with the silicone (remove tape while silicone is still 'wet').

Interesting idea. Messy, but interesting!
 
I was actually thinking of lining the inside of the tank with the hardi boards and cementing the joints, as well as using some type of quick set mortar or cement and spreading it below the hardi boards. Just like you would laying tile floors. I would also use liquid nails.

I am probably going to try a small tank in the next few days if not today and making it out of just plywood and concrete. See if it sticks to the plywood. Than just wait until i get the drylok.

The taping would take hours!

I've had an idea along those lines as well. Until I realized how much silicone you'll need! It worked out better for me to fiberglass than to tile.

BUT I would also like to see someone try it one day.
 
Concrete or cement would be interesting, but if the walls bow to much the cement will crack. Hardi-board has more tensile strength to it, so its a better option than cement.

You could use a layer of synthetic stucco on an assembled tank. That would look pretty good and it has more give to it than cement.
