I have 3 healthy fish, 2 healthy corals, an urchin and plenty of inverts. I do a 10 gallon water change every week and have the fish store check my water once a month. I also change out the lights once a year. However, anything new I put in, fish or corals just die. And recently all the rocks started turning red. Not slime or cyano, just red. So I am done. I am tired of pouring money into it. I just don't have the energy or the passion for it anymore.
