So, the mermaids, got into the moon pool during a lunar eclipse. The lunar eclipse makes their tail go away only for that period that it occured up to twelve hours. After that everything goes back to normal and they transform into mermaids regularly, when they come in contact with water.

Lewis says, that they will LOSE their powers 12 hours after going into the moon pool after the lunar eclipse. But he only tell them after the 12 hours. Emma is swimming in their family pool, Cleo is in the bath tub and Rikki is walking by the shore (in the water).

pay attention to the show

They went in yhe moonpool when it was a eclipse and it loses there tail for 12 hours and after 12 hours they are mermaids when they thouth water again.
