All coral need some level of NO3 or PO4 to grow. Since most of us are using hobbyist level test kit, although the reading is undetectable, there is bound to be some level of NO3 PO4 present in the tank.

Even for SPS tank, the recommended level of PO4 is 0.03 and NO3 is 5-10ppm. Having too clean a water and you risk your coral die out of the blue after months.

子非鱼,焉知鱼之乐... (you are not the fish so you...)

Then: my 4FT low tech selling off tank... (2006)

Now: (2014)

Although I measure zero, i still have some algae growing which requires me to clean my glass about 1-2 times per week. Hence its probably undetectable by the test kits rather than being truly zero. Agreed that its not about zero nutrients, but rather having low nutrients, enough sustain growth of your corals and minimise nuisance algae growth
