We have a Gould sewage pump that we use to pump water to our waterfall. It is a nice powerful pump so powerful that it sucks up our fish! For some reason the fish really like to hang out around the pump, it must be the current it generates or something. Anyway, is there something we could put the pump in that will allow waterflow thru' and will keep fish safe? The pump stands 19" tall and is about 13" wide. Thanks!
