Temperature - Saltwater

Water Quality

Water temperature for saltwater tanks is similar to freshwater ranges. The water should be between 75 F to 82 F (24 C - 28 C).  Fish will survive for short periods in temperates between 70 F and 85 F (21 C - 29 C).  Low temperatures can cause some bacterial diseases such as saltwater ich to flourish.  Temperature variation will cause stress and promote disease, so it's important to have a good heater or a chiller to keep the temperature stable within the acceptable range.  The decline of coral reefs has been associated with temperature changes of only a couple of degrees. Coral generally turns white and dies under temperature change.
