Reef tank

I had a salt tank for a short time ~25 years ago (as a teenager). At the time I read Martin A. Moe's handbook and reference. About a year and a half ago I started a project to try keeping sea squirts in my lab. They were difficult to keep and the tank crashed twice. I decided to bring it home and set it up for fun and to teach my self a bit more about keeping marine invertebrates. Looking forward to learning all about corals and maybe keeping a stray sponge or sea squirt in time. Looking for low maintenance but pretty in the short term while I get my sea legs.
