I started back in the 80s in High school so that makes it 30 years. I still consider myself a newbie until I can get my tank looking like the tank of the month. My first tank was a 10g saltwater with undergravel filter. Gravel was plain white sold for freshwater tanks, tap water mixed with salt, and white dead acropora skeletons as decorations. No internet or clubs to learn about reef keeping. Just books and magazines from the library. SPS, Duncans, Chalices, etc unheard of at that time.
Of course there were numerous of tank crashes, diseases, late night water changes, emergency spending for broken pumps, leaks, higher and higher electric bills. Sometimes I wonder why Im in this hobby for so long
