What do you supplement?

[soviettaco]

For a 24g nano with soft corals in it should I be putting any supplements in? Or do you think the tank should do fine on its own, do the corals, shrimp, and what ever else need anything besides food, a cuc, frequent water changes, and your basic parameter tests (p.h., ammonia, nitrite, nitrate, s.g.)?
If you need more info to help answer my question here is my latest full stock list and test results:

When I had a nano the only supplement I used was a limewater autodrip to replace evaporated water.
