Some fish tanks require an aqarium chiller not a heater

 Believe it or not, but the water in your aquarium can often be too warm for certain fish and plant life.  This is when an aquarium chiller is needed.  The function of an aquarium chiller is to keep the temperature of the water within a certain range that is optimal for both the fish and plants.  If the water is either too hot or too cold, the fish and plant life will not be as happy or healthy as if the water was the perfect temperature.

The type of aquarium lighting, how long they are on for, the temperature of the room will impact your tank’s water temperature.  To create the right water temperature, you can choose from either a drop-in or in-line aquarium chiller.  Drop-in chillers have cooling coils that you place in the sump.  These cooling coils lower the temperature of the water.  The best part with this type is that there is no plumbing required.

A more complex aquarium chiller is the in-line chiller.  Water is pumped in the chiller, cooled to the right temperature and then pumped back into the tank or sump.  You will need to get either single stage or dual stage temperature controller.  A single stage controls the chiller only while a dual stage controls both the chiller and heater which are excellent at minimized water temperature variance.  The less, variance the better.
