Twin Fan plus ATC999 Fan Controller

This package provides you with a Twin Fan and the AquaCool ATC999 Fan Controller to help prevent your aquarium from overheating.  The AquaCool Fan Controller will only switch the fan on when a specified temperature is reached and no longer has to run 24 hours a day. The controller includes a temperature probe to measure water temperature and determine when to switch on or switch off the fans. In addition to increasing room temperature, the heat generated by multiple powerheads, skimmers, return pumps and aquarium lighting can easily cause temperatures in your aquarium to rise to levels that are detrimental to fish and corals.

It should be noted that cooling fans are not as efficient as aquarium chillers, but they will help to lower tank temperatures by 2 or 4 degrees. An aquarium chiller is still a necessity if you battling with rising temperatures.

How do cooling fans help to lower water temperature? Cooling fans lower water temperature by promoting evaporation, venting warm or hot air from cabinets and lights.

Fans can be directed to blow across the surface of the water causing evaporation and lowering the water temperature in an aquarium.  A major downside of using cooling fans is that evaporation increases greatly, requiring that freshwater or RO/DI water be replenished.

Having one or more cooling fans directed upward at a metal halide pendant or T5 light fixture blows heat from the bulbs away from the surface of the water, easing the burden on the chiller. Cooling fans used in this way may even extend the life of the aquarium lights and ballast.

Used with a timer, the fans can be turned on or off automatically to coincide with the lighting schedule.
