Sudden condition changes can cause devastating fish kills. You can be prepared to address such situations by having a Kasco 12V Emergency Aerator on hand, ready-to-go. The powerful, 275 watt motor provides excellent oxygen transfer and can provide short-term aeration in up to a 1/3 acre pond or emergency aeration in much larger ponds. These units can also be used in remote harvesting, seining, sorting of fish. Additionally, the portable aerators are effective for temporary aeration during aquatic herbicide applications.
