Decided to get back into the hobby after about 30 years, and I must say that things have certainly changed! Under gravel filters were all the rage and bio ball setups were becoming popular. Keeping coral was all but impossible for everyone but the most dedicated. Anyway, here's my new to me 80 gallon set up. It's ready for water as soon as I get something to cover the back so I don't have to look at the wall.
