I need some suggestions for a pump to pump both fresh and saltwater up 2 flights of stairs for water changes on several upstairs aquariums. I currently have a 100ft hose in the basement that I cah pull up the stairs to pump the water. I just need some pump set up. It is just for water changes and does not run continually. Is there any kind of utility pump that would not cost an arm and a leg to set up in my basement? Perhaps some type of home sump pump... but I do not know how it would hold up to the salt. I thought that maybe I could just flush it with fresh water after use. Any suggestions would be appreciated.
