Would like to add

More blue lights to my Biocube 32. Looking for something to enhance the coral. Does coral require white light to grow? How many hrs a day is white light needed? I really prefer the blue light...

Would prefer to keep the stock hood though open to other ideas if it really is beneficial.

StevesLED sells a kit to retrofit the lighting.

Not cheap...but you keep the hood.

A light upgrade is warranted for sure. That retrofit kit is expensive though.

Coral does not require white light to grow.

I used 3M tape to put 21 led USA actinic strips under my hood, I love it.
