Yellow leather Toadstool turning brown

[whatcaneyedo]

Mine was marketed as a gold fiji however the only Sarcophyton I've personally seen that was 'yellower' was a newly imported artificially dyed specimen. I'd like to believe this practice is no longer done but I don't know for certain. Zooxanthella is brown. The pigment that coral produce as a 'sunscreen' is coloured and so the shadowed areas of the tissue of coral is typically less vibrant and more brown than the heavily exposed areas.

Anyways:
250W Phenix 14K MH DE in LumenMax
Bottom
30x and indirect
78F
1.025
Ca +400ppm
Alk 9dkh
Mg 1350ppm
PO4 and NO3 undetectable with hobby kits but slightly higher than I would like.
