Lost some color

Hello 3 reef!! I have had some of my corral for about a year, they all seam to be in good health eating and even growing, but some seamed to have lost some of ther brightness. Is there any suggestions on anything i can do or am not doing to counter this?

What types of corals?
And what are your phosphates/nitrates?

 

lighting?

 

some of my anemones and my sea apple loog smaller but still very active. im just now going to buy a water tester i always take samples to my fish guy who says everthing is ok, but i have not descussed tis issue with him just yet.

 

If things are bleached (turned white or vary pale) then you have too much light.

Also, I do hope you are aware of the caveats with keeping a sea apple.

 

no im not ive had it since i started. what do i need to know? i know they can be very toxic if they are stressed. Im hopeing that dose not happen its been through quite a bit at the start it was the fist think i bought over a year ago so i hope to keep him happy.
