180g peninsula tank build - First ever aquarium

[Milad]

well the thing is I only have 150 MH so I wanted to get some height on the rock so I can put a few SPS in there. I can remove rock later right? When I get the new sump in Ill have more room to put rock in the sump.

Im also thinking of putting a small rubbermaid container in the sump to act as a refugium. Anyone think thats a bad idea? I dont want to put glass in, I was just gonna put the container in and drill some holes to let water slowly flow through.
