Effective and safe control for infections caused by bacteria.
Application
Add 5ml per 20 litres (4.4 gallons) of aquarium water. Treatment should be repeated at weekly intervals. Prior to redosing, it is advisable to perform a 20-30% water change, using tap water conditioned with AquaSafe. In addition to adding General Tonic, we would recommend that you seek advice as to any possible underlying causes.
We recommend seeking further advice from your aquatics outlet, as often health problems are triggered by environmental stress.
Read instructions carefully before use
