Taking Care of Fish During a Power Outage

Written By Bill Wymard, Marine Biologist

Without power there is not much that can be done with filtration on the aquarium.

The fish and animals, if not overloaded in the aquarium, should be okay for a few days filtration wise. Do not feed the fish or do any cleaning of the aquarium as this can add to the overload of the filtration system.

The most important, immediate concern for the fish in the aquarium is gas exchange, oxygen in and carbon dioxide out. This occurs in the aquarium at the water surface. Moving the water at the surface increases the surface area and thus increases gas exchange.

This can be created manually by using a bucket. Put holes in the bottom of the bucket and position the bucket above the aquarium. Fill the bucket with water from the aquarium and allow it to drip/splash back into the aquarium creating increased surface movement and increased gas exchange, oxygen in and carbon dioxide out. How often should the bucket operation be performed? The fish will tell you. When they need oxygen, they will go to the surface and hang there “this is where the greatest concentration of oxygen is located”. At this point, perform the bucket operation.

Other options are the purchase a battery powered air pump. This will bubble and allow the surface of the water to agitate. Another option would be to run a battery operated fan and have it blow across the surface, again to cause agitation. The surface agitation allows carbon dioxide to be released and oxygen to be absorbed.

A small water exchange, no more than 25% can be done which also will help a bit by adding fresh oxygenated water to the system. This however, without the filter system running, can only be done once or twice over several days, any more than that amount will be too much of a shock for the fish.

Bill Wymard, Marine Biologist

Owner Bill Wymard set up his first aquarium at the age of 10. He had no idea that, several decades later, he would be keeping over 500 aquariums, and still possess the same passion and enthusiasm for aquariums and fish that he did when he was young.

As Wymard grew, and earned his degree in Marine Biology, that excitement and passion became something more. It just seemed natural to him to blend his life-long dream with his marine knowledge and skills to build the biggest (and best) aquatic superstore in the country. In the late 1990's, with the help of many talented, business colleagues from Petland, Bill, his wife Sandy and Petland owner and mentor Ed Kunzelman did just that!

In June of 1997, a new Aquarium Adventure franchise opened to rave reviews from local and visiting customers alike. Designed to hold and showcase the largest selection of freshwater and marine fish in the nation, our 12,000 sq.ft. showroom quickly earned a sterling reputation for the best selection of aquatic life and custom tank design in the area, as well as a knowledgeable staff.
