[Joeteng]

I have a 2yr old tank and till now it is still not stable. Whatever i put new fishes or coral, sooner or later they die. Those pioneer fishes in my tank are ok but new stuffs i place is not lasting at all. What actually went wrong? I have give up on buying at the moment. Please help. I have a chiller and good lighting as well.

Good water perimeter is needed for a successful reef tank. Its best to have your water perimeters checked and see if they are all at the acceptable levels....
