We live in an area with frequent power outages. When the power went out, I used to add water to the main tank until the bioballs in the wet/dry filter werere submerged. After about 8 hours if the power was not restored, my husband would bring a generator home. We finally got a 20 KW generator. I think if we did not have a generator, and the power was out longer than 8 hours, we would put the bioballs in a mesh bag and toss it into the main tank.
using bioballs as a bio media in a place with frequent power outage seems like a pain. well i think i will do this if the power outage will last for a long time
You are right. Wet/dry trickle filters provide excellent biological filtration, but a long power outage will wreck havoc with the system. This aspect of wet/dry systems and power outages bothered me a lot, and I decided to go a different route for biological filtration on my big tank. Since I made my decision, though, we got a generator that kicks on when the power goes out. A generator is peace of mind for the fishkeeper.
how many hours do you think the bb will last when the power goes out? yeah a generator definitely is a big help for places like ours
