A crappy topic. My drain field is showing signs of failure, such as surface water spots.
Research has convinced me that chemical additives are a temp fix, if a fix at all.
Replacement is a $20k plus deal.
What does have my attention is converting from an anaerobic bacteria system (slim is a by-product) to a aerobic bacteria which eats everything.
This is achieved by introducing oxygen into the septic tank.
A product that does this is the Septic Genie (google it for a description).
The claim is that the bacteria double every 20 minutes and within a couple of weeks, the tank water is clear and the drain field clogging will be improved and on the way to being restored from the new bacteria moving through the system..
I would be interested in comments from those who have experience with this technology.
Thanks.
