What is the password that you have to enter in order to take the big helmet of Qs head in Zero Escape time dilemma

I have a quest that is asking me to catch a Craig Barramundi. I am standing on the pier of the lake where the quest says it should be, but I am not catching much.

How long does it take for a pokestop to refresh. Once used it turns purple. How much time does it take to go blue again?
