I’ve added info about the DASTA Bio Balls being used before. They have been in the news recently as tens of thousands have been donated to the flood relief effort in Central Thailand and some even made it on to the TV news when they were thrown out of a helicopter into flood waters. ( Although that did seem a bit pointless as a few thousand small balls aren’t going to clean up billions of litres of flood water.)
These magical little balls help clear up polluted water. They can be used in both freshwater and brackish water. Best of all they are 100% organic and were developed in Sakakkok village on Koh Chang. Live bacteria and enzymes in the balls helps clear polluted water within hours.
This is a recent video of the balls being used outside Blue Lagoon bungalows at the south end of Klong Prao beach.
