RO/DI water, a good salt mix and regular small wate rchanges, it will contain everything you need for LPS and softies and in the recommended amounts. Leave the other stuff on the shelf at the LFS where it belongs. Unless you know something is in fact depleted, your system has a demand for it and it is in fact a necessary elemnt then don't put it in your tank. It is extremely easy to get a reef system out of balance and a real PITA to get it back where it should be. Most supplements contain more than one substance and at who knows what levels or if it is even necessary so pass on them until you have a better understanding on your tanks needs. Start a regular testing program using reliable test kits like Salifert to establish a baseline before you add anything at all other than your salt then if it shows something is lacking add ONLY that substance one at a time and monitor the results. Adding multiple products or additives at the same time can lead to trouble and you cannot identify which was the problem. Go slowly and spend time observing your system and its changes.
