Substrate
Here you need to decide on what type of material you want on the bottom of the tank, as well as whether you want to start with a live or non-living medium.
Shelter for Livestock
Many marine animals, fish in particular, can be quite territorial. It is important to provide ample shelter or places where the animals can hide, sleep, and avoid potential problems with aggression from other tankmates in the confined space of an aquarium.

For smaller aquariums one heater works well, but for larger systems the use of mutliple units is advised.

Additives & Supplements
For live rock and reef tank systems, calcium (a.k.a. limewater/kalkwasser) needs to be added. Other supplemental vitamins or additives that are beneficial to the health of certain marine inhabitants you may be keeping, such a iodine for crustaceans, are important as well.
Maintenance Tools & Supplies
This category includes having items on hand such as a various sized plastic buckets or containers, tank cleaning tools such as a siphon tube/hose, an algae scaper or magnet, as well as nets of different sizes, spare equipment replacements parts, and so on. A good way to keep track of what maintenance tasks you have preformed and when is to keep a log book or record of everything you do.
