Help!!! Zoas Dying?

[raidedxelite]

Hi everyone,

I have a 13.5G nano tank setup for a few months now. I recent added some zoas but they appear to be turning brown! They're ere pretty vibrant when I added them about 2 months ago but they're slowly discoloring.

They were about half way up in the fluval Evo 13.5 which has 12k LEDs

I've read that they could be getting too much light so I moved them to the bottom but they won't fully open as you can see from the pic below.

I moved one to the top to see if maybe it's been not enough light but I'm at a loss.

All my parameters are perfect. Calcium was a little low (420) but I'm bringing it up.

Take a look at the pic. Any idea if this is happening due to too much or too little light

all parameters are fine means what?? what are they would help us out ..also zoas look fine to me ..you really wont get the "pop" unless you have a blue spectrum lighting.

Ooo is that normal? They do pop under the blue light, they just seemed to be turning brown under the whites. Didn’t think that was normal.

depends how high you have the whites lights at
