well everything in my tank was established, it came from my dad's 90G bowfront and then i added two pieces of cured rock from salty, and then i just started adding fish, i am slowing down though and adding corals now, im learning more and more and thats why im just adding SPS corals now, they are small pieces and im seeing what i can do with these before i continue, i know alot of people are telling me that im going too fast, but now i need to upgrade my skimmer and my stand to fit the skimmer
