So a guy offered a 125 gallon tank for $200 and I took the deal, was really interested into making it a saltwater since my last tank didn't survive the move (besides my anemone "queso"). I needed help in deciding almost everything since ive never tackled a tank this large before. I am also on a kind of tight budget and would like as much as can be to be DYI, just for the fun of it. so what kind of lighting would I be using, should I drill the tank or use a overflow box, people say they arnt very reliable. do I really need a skimmer for such a large tank and no coral? Finally stocking, my only true desire for this tank is to have some kind of puffer, I am open to all suggestions as long as they are awesome to look at.
