I am thinking about taking some extra liner I have, digging a hole, lining it, filling it with kitty litter and pond water and sticking a lotus tuber in it. It would be about 100 - 200 gallons. Would the lotus tuber easily break through the liner and cause leaks? Maybe I should use a stock tank or something else? I would just like to use liner since I have some extra pieces that would do the trick. \n\nWhat are your thoughts?
