Be sure it's the tetras first, i've had my tetras and guppyies together for about 5-6 months and never had any problems like this. Guppyies are prone to fin rot from what i have been told and i've had x2 my self with fin rot, try using some finrot medication like waterlife protozin, cleared right up within a week or two for me.

Add to that a good large water change.
