How could I use a GameObject array to check the associated tags and toggle their Box Colliders accordingly?

At the moment I'm trying to use an array to check each element's tag and change that object's Box Collider 2D state for each one I want. At the moment the size of the array is 7 where each element has a Game Object selected. using UnityEngine; using System.Collections;

 public class scrHitboxStateUpdate : MonoBehaviour
 {
     public GameObject[] arrCollection;
     void Update()
     {
         for (int i = 0; i >= 6; i++)
         {
             if (arrCollection[i].tag == ("GameObject")) //Where object triggers will not be used
             {
                 arrCollection[i].GetComponent<BoxCollider2D>().enabled = false;
             }
             else if (arrCollection[i].tag == ("TriggerObject")) //Where object triggers will be used
             {
                 arrCollection[i].GetComponent<BoxCollider2D>().enabled = true;
             }
         }
     }
 }

However, when I execute the script the objects' BoxCollider2D enable state remains unchanged and no errors show up in the console. I'm pretty confused as I'd expect this to work.
