Go to the zeovit webpage and follow G Alexander. You will need to use most of their products to be successful as some additives feed the corals, some feed good bacteria, and some solve problems like cyano bacteria. Remember that waterchanges are required and you will also need to add potassium as the Zeo strips potassium from the water. Shakes the stones often and when you see phophates rising you need to refresh the Zeolite (Stones). Do not change more than 50% at one time and autodose your ZeoStart from the beginning. Just some advise.
