We often get too busy in our daily lives to test water and perform maintenance as often as we should. Because of this, our water parameters can easily slip from acceptable levels. Salinity is typically one of the first things to fluctuate. A few days of evaporation can lead to a drastically increased tank salinity. Upon discovering this, some aquarists might quickly react and begin pouring fresh water into the aquarium. This is not the most ideal fix. The livestock in the aquarium has become adjusted to the higher salinity, and suddenly dropping it might actually do more harm than good. Drop the salinity slowly, stretching it out over a few weeks. This may be an overly cautious approach, but it’s better to be safe than sorry.
