Hey everyone. I am thinking about building a plywood tank, but instead of using epoxy I am just going to put a epdm liner inside of it, its really going be a indoor pond you can say.

I have some questions though regarding this. I plan on this indoor pond to be 300g-500g range.

The questions are; 1. Is there a special plywood I should use for this? Also what size?

2. Support, how do you guys build it so it doesn't bow? Am I going be building a 2x4 frame around it?

3. Filter wise, since I am using a linear, should I not cut a hole through the liner and wood so I can connect my canisters to it? Or should I just plumb it so it hangs over?

4. I am not quite sure exactly how I am going to brace the liner inside, does anyone have any ideas?
