Problem in changing the color of Zoans

No. 1 Zoanthus at the beginning and put it inside the aquarium
No. 2 and 3 are Zoanthus currently .
Change occurred in bright blue turned into dark blue

Lighting: DIY LED 80 Watt (12 Royal blue + 8 Natural white + 8 purple + 4 led 3 colors red+green+blue on each star ) total = 40 led

royal blue and natural white is 3 watt CREE

Nutrition: Phyto Once a week / Zoo Once a week

Is the problem in lighting or nutrition?

 

Brigter light will probably turn them back to the lighter blue. Zoas will morph and change color often from one tank to another. Factor include Light, Nutrient Lever, even flow.

 

+1 Yep they look healthy though. Generally Zoas will let you know how much light they are receiving/needing.Not enough and they will stretch up towards the light.(usually) When they stay tight to the rocks they are either receiving alot of light or very heavy flow.

 

Most likely you are seeing light inhibition. Turn down the power to all of your LEDs.

 

ingtar_shinowa : thanx ..... These images without white LEDs
When running Full LEDs become very bright lighting and be close to 14,000 Kelvin
Poor flow around Zoas .

Vinnyboombatz : thanx ..... Zoas is very healthy ...The problem only in colors.

2in10 : thanx ..... Do you want to Turn down the power 20% for example ?
the dime in White LEDs only.

 

Plus LEDs can morph the color of corals.

 

All channels down 10% to 20%.
