Advise an ideas needed for a build I'm gonna be doing

[Jimmyman]

My idea is a saltwater pond for a few big saltwater fish . It will be incorporated into a bar of sorts. 12 ft across probably 5 TF front to back and we'll height will be determined with seating I use to go on both front and backside on the left and right I'm going to build a shelving unit in which the bottom shelf on both sides will house the flirtation and pumps. Other then then I'm trying to figure out what would be the best pond liner to use and should I double up the layer of liner. This project will begin in a few months

45mil EPDM liner should work fine. Your biggest concern will be the depth of the water. Building something bar height will put a lot of outward pressure so you'll really have to brace it up to manage that.

Do you have a sketch of what you're planning?

I thought on that and decided on 4x4 framing along with 4x4,s going all the way around . I'm definitely going to look in a few other things as how they will connect to each other so that they don't rip apart but also something that won't rip interior liner
