beginner starting sal water tank

So I have a 29 gallon tank that I have purchased. ( 30X12X18) I decided I want to start a salt water aquarium. I have been doing research and aware of the equipment ill need. Just want some input on if there is anything else that I will need, any suggestions, or something they would refer or recommend.



live rock

sand

heater

salt

protein skimmer

hydrometer lighting



also what are some specifications and considerations for having anemones in the tank?



thanks
