Re: CAUTION - CAUTION - CAUTION
Rejuvenate Septic Field
CAUTION CAUTION UP FRONT ! ! ! If your tank has no baffle wall in the middle, expect to have problems with an aerator. My tank is the older design with just one chamber inside, and no baffle wall.

The problem is that solids get broken down and recirculate around inside the tank instead of falling to the bottom. These tiny solids get forced through your effluent filter and end up as black MUD in the exit pipe going out to your septic field, thus clogging up your septic field to require rejuvenation..
I discussed this problem with my aerator dealer and the technician recalls one customer with this problem, and he fixed it by placing a culvert vertically with the aerator inside to prevent water from circulating around the tank. This forced circulation up & down inside the culvert, yet the oxygen in the water still spread all around the tank.
I will do the same, except use an aluminum pipe. Full details on this Aerator Enclosure with photos here:

7/17/13 - Update. The Aerator Pipe failed and so did adding a LOT of aerobic bacteria to the tank. I have abandoned the aerator and gone back to my Anaerobic tank. IMO, it is just not possible to aerate a tank without stirring up the sludge, new solids & scum into Septic Soup that squeezes right through your effluent filter to clog up your septic field.
A NEW CAUTION ! Sodium Percarbonate mixed with water works great the first time, but becomes ineffective with repeated applications. The reason is that it breaks down into sodium

that clogs the septic field by creating "Hardpan." Detailed description here:

See this shocking video about hardpan:

Even worse, sodium gets into the septic tank & leachfield from laundry detergent, oxy-clean, soaps & human waste.
All the more reason to pump your tank every 5 years, to get rid of the sodium.
