Are there any products or additives I can use to make my septic system work better?

The short answer is: no, there is nothing you can put down your septic tank to make it work better. Placing additives in the system is an unnecessary expense, and none of these products eliminate the need for routine maintenance and pumping. Adding a stimulator or an enhancer to a septic tank to help it function or “to restore bacterial balance” is not necessary. The naturally occurring bacteria needed for the septic system to work are already present in human feces.
