Aren’t you worried about the copper leeching into the rock? Or are going to remove the rock and sand

@Ortho281 - 1st, is this mixing station in a closet and if so, can you step back a few feet and tke a couple of pixs b/c I would like to see how you built it or if you're just using a closet?
I am getting ready to set up my saltwater mixing station next to my new SC Rimless 150 but instead of installing it in my garage, I am going to build a closet for my Saltwater mixing station to hold my two 25 gallon Ace Moto containers. I want to do it like your how you have it Vertical instead of the storage barrels sitting next to each other. Here is a shot of mine but I haven't glued anything together since I might want to build the cabinet over the stand with the barrels sitting vertically.
Yes, all my equipment is in a fish room adjacent to the aquarium. Since this was a new build out I was able to make the fish room exactly 2'x4' to hold all my equipment and not take up too much space!
