Just finished having our septic tank pumped and the drain pipes snaked for a blockage.
Other than being careful about what we flush, what are some good ways to keep the septic bacteria healthy and happy?

What I learned was, there are store bought products that renew the bacteria/enzymes that help break down solids. Apparently, they must be applied regularly, since the soaps we flush can kill them. One of the septic guys suggested filling the kitchen sink with warm water before going to bed. And add a packet of baker's yeast with a little sugar to activate it. Then, in the morning let it go down the drain. He said he cleaned an elderly couples tank who did that twice a month and there was no scum cap floating in the tank. He said the scum cap indicates poor bacterial action.

Anybody have any methods that have worked well? We have no access to the inflow side of our septic tank (under concrete steps) and better bacteria management might help limit visits from the Snake Master.
