Current is another important key to the success of your corals. Using two Maxi Jet 1000's will ensure enough current for your corals. We often add a third powerhead as the reef matures. A skimmer is also recomended for proper filtration. Many of our reefs do not have skimmers.
Water quality is essential for coral survival and growth.
Ammonia and nitrite levels must be at zero before adding corals. Nitrate levels can be at one or two, in fact some literature states that corals need low levels of nitrates in order to grow and develop. Water temperature should remain stable at 78-80 degrees with a consistant pH of 8.2. A salinity level of 1.023 is good for coral survival and growth. Many organisms, such as shrimp, that can be purchased for the marine aquarium are reef safe.
