<i>Microcystis</i> bloom control using hydrogen peroxide and floating sodium percarbonate algaecide Lake Guard Oxy in Florida.

ABSTRACT: Harmful algal blooms (HABs) pose a critical threat to aquatic ecosystems, human health, and economies globally, necessitating effective mitigation strategies. This study investigated the efficacy of two hydrogen peroxide treatments, liquid hydrogen peroxide and sodium percarbonate algaecide Lake Guard Oxy (LGOxy), in the field during a Microcystis bloom in the Caloosahatchee River, Florida, USA. Initial results indicated bloom suppression following both the liquid hydrogen peroxide and LGOxy treatments as 79% and 46% reduction in cyanobacterial relative abundance in 16S rRNA gene amplicon sequencing, 81% and 90% reduction in chlorophyll-a, and 91% and 97% reduction in Microcystis colony density. Both treatments were effective in reducing cyanobacterial abundance in the short
