Coopers DIY Brew Enhancer 2 Home Brewing Additive

Which enhancer should I use for stout?

I am brew a hops with Pale is enhancer 2 correct or go for enhancer number 1?

I’ve just bought a packet of brew enhancer and the product is solid. Is this right?

Hi everyone, Is the beer enhancer an additional step in the process to the brewing sugar and priming sugar or does the enhancer replace one of these?
