AACH25 Active Aqua Chiller 1/4 Hp

As the summer months get closer your room temperature will become more difficult to control. In many growing situations spending big money upgrading your air conditioning is not always the best answer it may be easiest and less expensive to simply add an ACTIVE AQUA CHILLER to chill your water. Plant root health can be diminished by high water temperatures any temperature over 67 degrees Fahrenheit can make your root system soft and susceptible to many root borne diseases. Oxygen is also a big factor in a healthy root system the warmer the water temperature surrounding your roots the less capable that water is in holding oxygen. That's right the colder the water the easier it is for that water to hold oxygen but don't get too cold as your plants roots will be slowed in their ability to transport vital nutrients to your plants.

Fresh and saltwater fish tanks also benefit from cooler water on those hot summer days. Growing coral is easily damaged in the summer by high water temperatures These ACTIVE AQUA CHILLERS are great for controlling your aquatic environment.
