Saltwater ponds question

[Dawneme]

Hi sorry dont know where to put this on, anyways so i wanted to make a shark tank but i thought of using those plastic over ground pool thing, or even a cement pond for cheaper alternatives than glass tanks

Anyone kept these before? If so please tell me your experience with it
Wether its an ok option than glass tanks, and their longevity

I assume this is outside. I saw your other thread about the shark tank and with those two sharks a 350G tank would be sufficient. Consider Rubbermaid stock tank.

Check my build thread if you are thinking about a stock tank build. Sharks and Rays need a lot of filtration and the giant UG filter can handle it . I know 2 people who are keeping Sharks and Rays in 300 gal stock tanks and so far it seems to be working for them. I would up the riser pumps to 4 from 2 and put at least 600 gph powerheads on them
