It has done great. I don't have it set up all the time, just set it up now and then when I want to feed some live food. Its not really hard. Just have to be careful and change out some old water and put new in every day so you don't poisen them. Also have to be able to feed them but not over feed. If you do a search with someplace like
www.yahoo.com most of the sites on how to do it very as far as salinity. Most of the sites also raise brine for freshwater baby fry. I use tank water so when they hatch my brine is already acclimated to my tank water so when I put them in they have a chance to run for the rocks and live for survival.
