coral depth

[Canadian]

There's a huge range depending on the type of coral, its geographical location, competition encountered by potentially more aggressive coral species, etc. If you're interested in this in an attempt to ascertain the amount of PAR, LUX or Lumens that a typical coral would receive on a reef, you also have to keep in mind that water clarity plays a critical role. Due to natural selection SPS corals are found in high flow areas where the water clarity is considerably greater than what would be found in a lagoon dominated by LPS.
