I currently have a 20 gallon aquarium, everything was booming....corals and fish. However, I preformed a 5 gallon water change at noon, and by 6 pm all my fish died. The corals seem to be all doing just fine. I immediately did a 40% water change and waited until the next day to check my levels. PH 8.2, ammonia 0, Nitrates and Nitrites 0, as well as Phosphate.
I then went and purchased 3 fish and within 5 minutes they all died. Corrals are fine....
All saltwater was purchased at LFS. I have used them exclusively for my saltwater with no issues up to this point....any thoughts what might be causing the this?
I also just did a 70% water change after this last incident..levels remain the same...PH 8.2, ammonia 0, Nitrates and Nitrites 0, as well as Phosphate.
Any help would be appreciated and I am at a loss what might be causing this?
