Potentiated Chlorohydroxyquinoline (PCHQ)
Aquamac Mac-Gard 'S' is a blend of potentiated chlorohydroxyquinoline, organic acid salts and MOS is specifically designed to eliminate Clostridia & Salmonella species apart from other pathogens.

Halquinol is recognized as one of the most approved non-antibiotic growth promoters. It is a chlorohydroxyquinoline compound and is the mixture of 5-chloro-8-hydroxyquinoline (MCHQ), 5.7-dichloro-8-hydroxyquinoline (DCHQ) and 7-chloro-8-hydroxyquinoline.

Vibriosis is a systemic bacterial infection of primarily marine and estuarine fishes, caused by bacteria of the genus Vibrio, a major cause of mortality in aquaculture operations.

Halquinol possesses a broad-spectrum antibacterial, antifungal & antiprotozoal property and has been appreciably indicated for the control of vibriosis in marine fish by Austin et al. (1981).
