Harmless cleaners?

[Dandelion]

We're wondering what advice you might all have for us. We've just had the septic tank cleaned out and were told that most detergents, etc. kill the bugs in it. soap is safe. So what can we use? Would baking soda or vinegar even be safe?

When I had a septic system. I would pour yeast down the toilet and that helped to break the stuff in the septic down.
