Plywood tank (pond liner + bottom drain)?

[small_ranchu]

Hi all,
I want to build a plywood tank with pond liner; no viewing screen at all. Is it possible to put bottom drain? Thanks

yes it's possible but it'll be an indoor pond, not a tank head over to that subforum for more info, plenty of them have done the exact thing.
