So funny to come across this thread. My husband and I were just discussing this, this past weekend when I was doing my water change. I take care of the indoor fish and I taught him to do the outside pond. I told him, if anything happens to me figure it out, just like I have to figure everything out! That being said, when he had surgery and I had surgery I made sure all maint. was done to give us atleast 2 weeks for recoveries. I also do maint. if I know there may be a BIG storm coming that could cause loss of electric. I’m a pre-planner for sure, but if I “pass on” someone will have to step up.
