I have been living in the Philippines for a year. I miss my old tank. Well tanks since I was in the hobby for years. There are no salt water aquarists here. I think I can get parts shipped here but not live stock. But I am surrounded by some nice fish and corals. Does anyone have experience using natural ocean water, substrate, and rocks without coraline? I am thinking something small that I can do easy water changes with. A few chomis, some leathers, and a native monti cap.
