Hi there fellow reefers! Just wanted to introduce myself and share a bit of info. My name is Mike and Im from Daly City. Ive been away from the hobby for a very very long time(10 years or so). I finally decided to jump back in! At the moment I have a twenty gallon tank that is housing a clownfish and a couple zoa frags. Since I dont have much space to work with my idea is to make a three tier system. I plan on drilling two ada 60p tanks with a sump on the bottom. The top tank would house my clown and z and p collection with the bottom one either a display fuge or maybe an nps tank with a tube nem and some nice cup corals. I cant really decide at the moment. My main worry at the moment is building up enough cojones to drill the tanks. So if anyone has some tips they are more than welcomed!
