I am near Los Angeles and we have had a couple small earthquakes the other day, so I filled up a clean 5 gallon bucket with tank water just in case we get hit with a big shaker and the tank gets busted. Its in a pretty sturdy spot but after 1994 I still get worried. Does anyone know how often I should change the bucket water to keep it good? Also I keep it covered so that dirt does not get in.
Thanks,
Chris
