It is a matured new tank. I got it from a buddy that had it running for seven years. I transferred everything over from his house, eqiptment, rocks, fish, inverts all in the water from the tank. So it may be considered new but was aged at one point. Im not sure if that matters at all. My water levels are all perfect besides my nitrates, which sit at 20 but reach 30 after a week. The hair algae is getting eaten by the tang now and is started to not grow as I moved ph's on them and started to do more frequent larger pwc
's. I also have a fuge getting put in tomorrow which will have some caulepra(hopefuly help with the microalgae). I also have some chaeto comming in a week.
