Nematode Problems

Hi everybody, just a few quick questions, growing in coco of course, straight botanicare, nothing else, 5 weeks into flower and I Flush my girls and I see a lot of Nematode popping around the top of the soil, the infestation looks serious, yet the girls look healthy, what can I do to rid myself of these suckers.

I got super grossed out when I looked up nematodes....http://entnemdept.ufl.edu/creatures/nematode/soil_nematode.htm

Azamax is supposed to kill nematodes according to the label.
