In many cases, yes, SPS corals can survive in amazingly little light although spectrum undoubtedly plays a part, as does feeding. Many - not all - Pacific SPS corals (Acroporas, Montiporas, etc.) contain Clade C zooxanthellate and are less tolerant of high light than, say, Clade A zoox. But these myths about SPS requiring high light intensity (define this vague term, please) go back decades and simply isn't true. I can provide hard data if you're not already familiar with it.So I have a reefbreeders Photon 48. I love the 20k look but have been told that my par of like 165 on the rocks with the light at that setting (100 blue, 5 white) is too weak for sps.
So in reading this that is quite possibly wrong?
