1) Check water equivalents regulary and keep them constant 

As simple as it may sound: The basic requirement for well colored corals are the water equivalents. Calcium (420 mg/l), carbonate hardness (7-8 °dKH) and Magnesium (1320 mg/l) should be kept on a normal level. They have no direct influence on the coloration of the coral but water additives, trace elements and other tricks don’t work if these parameters get out of hand. 

However the nutrient values are crucial fort he character of the SPS corals. Here the opinions tend to differ: The „old school“ recommends higher nutrient values, that means about 20-30 mg/l Nitrate and about 0.1-0.5 mg/l Phosphate. With these nutrient values very rich colors can be achieved, but then the colors are very dark and can get dark brown easily, because the density of Zoxanthellae increases. Zoxanthellae are always brown so the higher their density the more the brown algae overlay the actual color of the coral. Nevertheless a SPS aquarium with high nutrient values and beautiful colors is possible.

How to keep your fish alive and well

Seawater fish are subjected to very stressful conditions, especially when they are taken out of their natural habitat and are put into a closed environment, like an aquarium. Aquariums cannot recreate a natural milieu like that of the ocean that is very much needed for keeping the fish healthy. Stress is the reason for fish to get sick from infections, bacteria and parasites that are always present in water. Any aquarists have to check the water on regular basis for components, which may cause harm to fish. Filtration is also crucial for maintaining good water quality. You can filter water through a UV sterilizer, which terminates any germs, bacteria and parasites, which go through the sterilizer. Ammonia, nitrite and nitrate should be kept as well at a minimum.
