In the given experiment, the scientist is checking for the effect of more than one variable on the development of the coral, which includes the pH, the salinity, and the temperature. The conclusion that the coral do not grow in the water with high salinity is wrong as in that aquarium, the pH, and the temperature were also high. They could also have been the factors behind the decreased growth of the corals. One variable should be tested at a single time to arrive at a valid conclusion.
