The Battery Operated Pump Model is a must for anyone who has fish since it can provide auxiliary air when main air sources fail due to electrical power problems. It can also be used as a portable aerator for fish in transit. Comes with air stone and 18" tubing and can be operated with two D cell batteries. The 50 (15 Gal.) & 801 (15 Gal.) models are single output while the 802 (20 Gal.) and Maxima (30 Gal.) models are dual output. The Optima pump (30 Gal.) is single output but includes a rheostat for precision aeration control.
NOTE: Choose the model closest or just above your actual gallon size (ie. best choice for a 20 gallon aquarium would be the Model 802 gallon pump or a 45 gallon aquarium could run with two model 802 pumps if so desired).
