New to forum, and new to Pools

Hello, I just recently purchase a new house that fortunately has a pool. I am going to install a salt chlorine generator. My question is do I need to shock the pool, or could I use the super chlorinate function? The mesh cover is still on, I did look under and the water has a green tint, and I don't know what would be best. Also I have an Aquabot classic, can I use this to help clean the pool initially or should I wait until it's completely opened and clean, then use it to keep it clean? Any help will be greatly appreciated.
