Saturday's incident at the Formosa Water Park is believed to have happened when a coloured powder ignited after being discharged onto the crowd.
Footage showed people panicking and screaming. Inflatable water toys were shown being used as stretchers.
Some 190 people are seriously hurt - 182 are in intensive care.
