We didnt replace the leach lines since it passed a 40 minute test.The tank relies on bacteria to break down the solids, i believe the process is called anaerobic.Flushing down bleach kills the bacterias so just be aware of that.

Yes We are like bacteria accidentally benefiting from dropped crumbs: VOTE and in the meantime follow learned hand and the law

One consideration is that copper actually kills bacteria and algae unlike the plastic options. 

Most of the rest of the items should disappear quickly, even if the "cost" to the buyer is a bit of labor.It looks like Ozone sterilization is used to kill bacteria in the pipes:http://en.wikipedia.org/wiki/Sterilization_(microbiology)#Ozone <-- would indicate that spraying it around is a bad idea.http://www.luxuryspasinc.com/store/facts-about-ozone-sterilization.php <-- non-referenced business site, but gives the general concept of what you are looking for.

Nothing sounds better than having a non-professional using a DIY kit to remediate potentially deadly bacteria.

Here in MA, there is an annual compliance inspection, culminating in a "21E" certificate, meaning that the site is clean.One of the nice innovations in this arena over the last decades is that there are now bacteria that "eat" petrochemical pollutants.  

Septic tanks, even though they're full of crap (no pun intended), are sensitive things - the bacteria are highly susceptible to overload, bacteria soaps, bleach, chemicals, and other stuff that simply won't break down or will kill off the bacterial load.

Mold is a dangerous bacteria to be around and could cause significant health problems, as it sounds like you have begun to experience. 

I have a lot of concrobium and RMR 141 at home already - also thinking of getting some hydrogen peroxide.Curious if anyone else has done some DIY mold/bacteria remediation?

Food can clump together and cause clogs.Facial Cleaning Pads – Thicker than toilet paper and thus can cause problems.Dental Floss – NOT biodegradableHair – Clogs pipes in no time.Dirt – Dump it outside, not in the toilet.Dryer Sheets – Made out of synthetic materials, not biodegradable.Prescription Medicines – Destroys bacteria and contaminates groundwater.
