As pointed out in another thread, there are two types of septic systems. The older
anaerobic and the newer
aerobic, the newer systems are characterized by the inverted 'candy cane' in the leach field.
It seems this genie might help an aerobic system, but just stir the muck up in an anaerobic system and possibly let undigested material out into and plug up the field.
If I remember right, in the old days, on a plugged up field they treated it with acid to clean out the perforations in the pipes
