I've toyed with the idea of getting a small submersible sump pump with automatic shut off for a dual function. I'd put it in a bucket with a screen (to remove larger debris) and use it as a drain for my tanks. You see, I live in an old house (by Denver standards - 1910) in which the sewer line is about 6"/15cm above the basement floor, so I have no floor drains. The sump pump would pump waste water either out the window to the lawn and garden, or to a basement utility sink. I could then use it to pump adjusted water from holding drums into the few apisto tanks that need something other than my tap water. I worry about using a simple submersible pump because it might be damaged if it runs dry for any length of time and I don't want to be turning it off and on at every tank. I'd be interested in anyone's thoughts on this, pro or con. Mike Wise > > I'd like to come up with a system where I pump the water out > > of > > the can and right into the tank for water changes.
