Help please

Hi all,

I'm 2 years in and lights still confuse me.

I've got fluval 3.0 marine lights.
As I've said I don't understand lights good enough to apply my own settings.
There's 3 preset setting that fluval supply.
Deep sea glow
Sunny reef
Colour boost.

I'm currently using colour boost but I'm finding it's bleaching my nems.

It's a 250 litre tank so I don't think deep sea glow would work. ‍♂

Please help.
I'll attach the light settings incase you don't know them.

Tank is 2 years old and nems are being fed once a week.
It's affecting all 4 nems and the rest of the tank is thriving.
All parameters are fine.

Any help would be appreciated

I have a feeling it may not be your light. LEDs are pretty intense and nems do enjoy a lot of light... Can you post pictures of your nems under white lights with no blue?
