Pond foggers are completely safe to use with fish and other living creatures and can give your pond a cool effect, especially at night when used in combination with lighting. They are required to be kept afloat at the right depth using a “fogger float,” which is essential for proper operation. The best pond foggers should be fully or semi-submersible, have a long power cord for optimal usage, and come with a transformer and float. Some can also have color changing lights. Look for ones that use ultrasonic waves instead of chemicals. Ultrasonic sound waves vaporize water into a cool mist and they are completely safe for fish and pond inhabitants.
