Hi my name is Pamela. Are there any threads on taking over an existing aquarium? I am an RN in a memory care facility. We have a new management company that didn't want to pay the tank cleaners anymore. Tank cleaners were let go the end of last week. But my residents love the saltwater aquarium so i am willing to take it on for them. It is sad looking and has only 1 clown fish, 1 tang, a sea urchin and a few tiny things in shells. Its also plexiglass not real glass. I tested the water and no ammonia, no nitites and no nitrates. Ph was 8.2 and specific gravity 1.028. This may be because I asked when fish were fed last and no one knows. They are fed now. I have been bingeing on BRStv but there aren't many things on taking over an existing tank. I'd like to turn it onto a reef tank and get more fish. Any ideas or point me to correct thread would be appreciated. I do have a decent light system, a wave thingy and I believe the pump/filter is decent but I doubt anyone has done anything with it. It's 50 gallons I believe. 48 inches x 15 x 16 (water level). I guess I should measure to top not just water level? Thank you in advance. I'm at work, so will check in after. I would attach a pic but I don't see where to do that.
