About H2O Just Add Water
H2O Just Add Water premiered July 2006 on Network Ten about teens Cleo, Rikki and Emma turning mermaids at Mako. Season 1 sets 26 episodes with tail hides.
Seasons 2 to 3 from 2007 to 2010 add Bella and finale moons in 52 episodes. The show shares one timeline, so broadcast order keeps tails and moons clear. The pace stays steady across entries, with each part adding new faces without losing the core tone. New jobs appear often, with each fix teaching care without losing humor and keeping friends clear.
Good to know
There is no separate chronological order worth listing since all three seasons run in sequence. Watch Season 1 fully before Seasons 2 to 3, since Mako rules assume tail setup. Treat the run as complete with 78 episodes, and see Mako Mermaids after. Plan extra time for finales, since later parts assume full knowledge of earlier twists.
