Cycling question

1. So i bought a bottle of bottled bacteria (bio-spira) and was wondering how much do I put it in my 50 gallon? All the label says that the whole bottle is for a 75 gallon

2. Can I still be able to get clean up crews 2 days after I pour in the bottle?

3. Do these animals do well with each other?
Volition Lionfish
Goby
two clowns
Maybe (future):
snowflake eel
