fading coral

[diemaker]

have a large flavia that I've had for a while and now the color is fading a way the rest of my sps are great but I,ve also noticed my zoo's have started to be come shaggy and my clam will not open right up the flavia is about 10-12" from the light witch are 250W and run for 9hrs aday

I've also found it hard to grow corilin not really complaining but may try dripping kalk but don't really see the need for it as all my reading of k/h and cal never really move

I feed
freezed dried cyclopeeze 2-3x week
frozen cyclopeeze 3x week
frozen brine shrimp 5-6x week soaked in r/o-di

also been adding (aqua line plancto) 10 drops daily

nitrate no3-0
