Sick coral!! Please help!
We own a 180L saltwater tank with about 7 pieces of coral, 2 clown fish and a sail fin.
We recently bought another light as the aquarium shop recommended we do if we wanted to purchase more colourful coral.
Ever since we have done so, the coral seems to be dying. One of the coral has turned white, one has shrunk, one has developed blace spots all over it and they are all generally very unhappy.
We first took the water to be tested and were informed out salt levels were far to low, so we fixed that. All other tests are coming up fine??
Can anyone offer any advice? Could the lights be the problem?
