Hi everybody, quick backstory, I’ve kept quite a few fish for quite some time but only ever freshwater, I’ve been super interested in salt water and would like some help getting started. I would like to get a 10-20 gallon tank going . And I’m not sure exactly what I will need. I’ve read and listened to so many conflicting opinions, some people saying they don’t even need filters or protein skimmers or some saying it’s absolutely necessary and some saying just use live rock and a powerful powerhead. I would like to know what’s worked for everyone else and what species of fish and coral...etc; they’ve successfully kept. Keep in mind I’m in a bit of a budget . About 200-250$. Near Calgary too so supplies at LFS are limited.
