Ply indoor pond / tank build . Time for bigger

  • We are currently upgrading MFK. thanks! -neo
What you see is the bottom . I will be sealing and then i will fix a full ply sheet then flip it over, repeat the timber around the top as i have done with the bottom . Then i will fit vertical bracing timbers all around . A final seal then a liner will go in .
To finish it off i will put decking board around the rim and skin the outside with a as yet undecided material .

I will update with progress pics untill completion .
Plan is to move my israeli kio into it .
 
I have never did this so takes my advice as opinions not fact.
But I believe I would go with a liner. It seems to me that it would be easier, and less likely to have leaks.

I really want to get more done this weekend . I have checked for any bowing of the panels and found a difference of 3mm on the end panels . So i will be draining and fitting a horizontal brace in the centre of the end panels . Need to drain it to move it to get to one end . I am not sure if the 3mm of bowing on 18mm ply is acceptable but just to be safe :).
Any thoughts on this from experienced ply tank builders . ??
 
Looks good. Flexing is expected as long as it's built strong enough to not come apart I would worry. Because you are using a liner and the liner will flex with the plywood you shouldn't have any problems.
 
I meant to say I wouldn't worry. If the flex isn't enough to make the tank fail you should be okay
