Montipora slowly losing color

[fishguy2727]

I have had the 45 gallon tank running for almost two years. I have had montipora in there for about a year. They are not growing like weeds but are growing. Most seem to develop very bright coloration but then the fluorescence slowly fades (not browning out). Now some of them are almost white. They continue to grow and the fading is going very slowly, over months, so I don't think it is bleaching of any kind.

I use Brightwell: Reef Code A and B, Magnesion, Zooplanktos L, Phytochrom, KoralColor, Replenish, and Restor. I feed New Life Spectrum Thera+A, Hikari Rotifers, and H2O Oyster Eggs.

If this coincides with any changes it is when I first ran out of KoralColor. I tried to not use it because I didn't think it was doing much, but that was about the time the fading became more noticeable.

Since I have had the montipora I have switched from a 2x96watt compact fixture to a 4x96watt compact fixture. Overall everything is doing very well. I have a Derasa and a crocea clam, both have been in the tank for months, both are growing well and are very colorful. My LPS (Frogspawn Euphyllia, Fungia, Cycloseris, and Symphyllia) are all doing well. Mushrooms, Zoanthids, Ricordea, etc. are all doing well (but not too well).

Thanks in advance.

perhaps there is some chemical warfare going on between your lps and monti's do you run carbon what is your water change schedule what are your parameters alk, s g, no3, po4 etc?
