Metricide 28 activator?

[PJFISH]

What do you do with the little bottle of activator that comes with metricide 28? Do I need it?

I ordered metricide 14 and Amazon sent 28, is there a big difference?

I think it's stronger than met 14

 

[PJFISH]

I wonder if I have to adjust it then?

Metricide 14: 2.6%
