Dosing question

I currently have a 75g that went from fowlr to reef about 2 months ago. A friend gave me a few frags free and jumpstarted this. But I don't plan on going crazy with quantity. I want quality. But in a few weeks I am going to a 180g (so I'm hypocrite, quantity lol)

current stock:

2 clowns

2 damsels

1 sleeper goby

1 fire goby

1 royal grammar

Anthilia

Kenya

Toadstool

Mushrooms



Going to add:

Hippo tang

few cardinals

scooter

any maybe more



For corals I want

Hammer

gonaporra

Bubble



Wondering what I should consider dosing? I'm figuring with the bigger tank that dosing is going to be more important.
