90 Gallon Tank Can a new 2nd filter cause a cycle?

So on a 90 Gallon i added a 2nd brand new filter.
my question is will this 2nd filter cause a mini cycle on my tank?
i rinsed it well for a day before connecting but noticed my water clouded up on the 2nd day of running i didnt do anything different to the tank aside from set it up with new media and sponge. again I emphasize this media and sponge were properly cleaned in tank water and i had it sit with de chlorinated water the day before i ran it on the tank.
ill be testing it later today when i am home but i was wondering just to make sure im extra vigilant will adding a second new uncycled filter cause a cycle or mini cycle?

You've added more capacity for bacteria to grow and it's obliging. A new filter (installed as you have described) would not crash a cycle.

thank you, i just wondered why i would cloud up, if aquarium was crystal clear before adding the new filter.
