Battery Operated Air Pumps

Coghlan's 0817 Battery Powered Air Pump

Power failures happen sometimes but These can be deadly for your fish. If your tank is over crowded or if you have sensitive fish like Discus fish Then you need a backup system. It's fine if filter doesn't work for half a day or so but without an air pump things can get really bad. This is why you need to keep a Battery Operated Air Pump. This can save your fish. Specially in summer time temperature rise and fish need more oxygen. A sudden power failure can kill all your fish before you finds a solution.

 One way to do this is using a Computer UPS. This might cost you around 50$ but will save your fish from Power cuts and power failures. This need little bit work but if you have no idea how to do it then just by a Battery Operated Air Pump. Cheaper and easier to use. Some of these monitor your AC power and kicks in if there's a disruption in power and work like 8 hours. So these can be very handy if you need to go out where you will spend long hours.

This Silent Air B11 battery operated air pump continuously monitor your AC power to detect any interruption and will turn on automatically as needed providing your fish with life-saving aeration during a power-outage.Says can provide full power for up to 48 hours depending on the life of your batteries. But don't take words for granted always run is and see if it stay for 48 hours with new batteries. It will cost you pair of batteries but it's better than cost your fish their lives. It uses 2 Alkaline "D" batteries which costs around $6.00. Also this battery operated air pump will be very handy if you transport fish to another location.  Oh there is one another thing. Silent Air is just it's brand name. It's not silent. You might need to use some cloths to absorb noise.

Marina Battery-Operated Air Pump is another good one. Only downside is this pump is not silent. Best thing is with fresh batteries it works up to 20 hours. But another thing I dislike is use of D Batteries rather than more common batteries like AAs. But the solution is buy few pairs of rechargeable batteries along with the pump.
