Most of the reef building corals and animals on a reef are dependant on high amounts of sunlight; thus coral reefs are restricted to the tropics where sunlight is abundant. There are deep water sponge reefs in temperate and artic regions, but they are much different from coral reefs.

Atoll reefs usually only form where stony coral growth is quite rapid. They are far more common in pacific reefs than atlantic. However, an atoll is simply a coral reef that encloses a lagoon, and technically they could form anywhere where reefs form.
The 3 important conditions for reefs to be able to form and grow are shallowness to allow maximum light, agitated water for plankton, and optimum temperatures of about 73.4 and 84.2 degrees Fahrenheit.
