NT Labs Pond Treatment

Catalog No: 501894

Malachite Green is an effective treatment for external parasite and fungus infections. When used together with formaldehyde it's activity is enhanced which means that less malachite can be used. High dose or frequently repeating dosing can damage the gills of the fish. If the required effect has not been achieved after two treatments, take further advice to establish the real cause of the problem.
