When I decided I wanted to try acros I decided to set up a new tank. I wanted to be able to provide for a acros and not have to try and keep lps and softies happy also. Flow and light have been the most important things for me. My first tank was 36x22x22" and had 6 power heads and two photon 32s for light. My N and P has always been low and I dose ammonium and diy PO4 to keep them detectable. I keep things pretty simple and test alk, nitrate, and phos weekly and calcium every few months. I dose AFR to maintain alk and calcium and it's also supposed to keep trace elements in line from what I've read but I've never done an ICP so I don't know if that's true or not. I just moved into a new tank after three years and things look pretty good I think. My first coral in when I started was battle box of stags. I try not to buy fresh cut pieces because they've done poorly for me so I look for frags that are encrusting so I know they started growing after being but. I Don't have high end pieces.
