We live in a rural area where power outages can last hours to days. The first thing I do when the power goes out is to add water to the tank so the bioballs get submerged in the wet/dry filter. I throw in a couple of battery operated air lines into the tank. If the power is out several hours, we hook up the tank/filters to a large generator, which my husband has to bring home in a trailer. When the power comes back on, we test the water and do a big water change. This system works if we are at home. But what would happen if we were away for a week and the power was out for several days? (Last month we were gone for 9 days.) This is a very troubling question, especially since we are in the process of doing a major tank upgrade and building a fish room to house the new tank. We need a generator to kick on automatically to keep the fish tank running during a power outage. But why should the fish be warm and comfortable while we basically camp out in our all-electric house?
The solution for us is a 20 KW generator, so it will be business as usual around here during a power outage. It required getting propane on the premises
Putting in a transfer switch
When it is all done, my power outage worries will be over. Peace of mind.
