I'll having a slightly differing opinion here to the others. Talking to folks who work in the industry the consensus is that you don't need to put anything extra, just what naturally goes in there. That provides plenty of bacteria, bacterial additives probably don't hurt, but anything that promotes dissolving grease etc and getting it into the leech field is bad news. You can find recommended pumping schedules online for your size tank and family, but its generally 2 - 5 years. Other things to be careful of are not putting grease or harsh chemicals down the drain. Try not to use anti-bacterial soap and limit use of things like bleach, though regular cleaning with bleach products doesn't have enough to really matter in your tank. Basically if its not biodegradable don't put it down. The only other concern is not to drive or use heavy equipment on the field and be careful of the Distro box, pump box (if there is one) and tank itself, you can fall through it if you drive the wrong thing on top.
