Since your building this outside the tank you want you can scrap the epoxy putty and cement and just use pond foam and if you want extra structure you can still drill the rock and incorporate your fiberglass/abs/acrylic rods. No ph swings, material is light and easy to shape, easy to blend with rock and very adhesive.

All good input. I decided to buy the fiberglass driveway markers and some Quikrete Hydraulic Water Stop Cement
I also want to use foam and epoxy/sand to cover up gaps etc... but all the epoxies I saw said not safe for drinking water.
What kind and where can I buy this foam and epoxy in Canada? I went to Michaels craft store ...
