Septic Field Treatment

[jednastka]

My septic field (30+ years old) is starting to seep. I can accept the comment of "put in a new field", but I do have a little trouble with the price of $9000 or so. We put in a new Septic Tank c/w pump out to the field last summer because the dividing wall in the original one had failed, and we had been pumping everything out to the field for an unknown period of time.

I have searched on the internet and it seems that south of the 49th it is very common to treat the field with "enzymes" and "bacterial cultures" to eat the biomat created, thereby adding to septic field life.

My questions are:
1. Has anyone here tried a treatment?
2. What was it, and did it work?
3. Why shouldn't I try a treatment like this (for about $400) as a first step to see if I really need a new field?

Thanks;

Vic
