Interpet Bioactive Tapsafe

Hi all
Could someone please tell me how much interpet bioactive tapsafe you put in water when your only topping your tank up.

Never used it myself but would have thought it would just be proportionate to whatever you dose per gallon/litre.

Does it not say on the bottle, OP?
