Some recent pics.. over the period of years, the tank suffer some up and down , red cyno, bryosis alage bloom , massive kh fluctuation due to c02 tank running empty on Cr .. anything that can happen in the hobby, you name it and it can happen over time if you reef long enough. loss some of the sps, some STN but manage to save some in my frag tank for regrowth later on..
