Coral Life Bio Cube 29 LED's

[bothfly]

So I understand the 29 has 4 Open slots for LED's.
Is this a worthy upgrade?
Should I get all White or a Blue one as well.
Thanks

these are for visual appeal only. they do nothing for growth

Really, so not worth it if I want to do Corals....

Makes them look better. Most lps and some sps will grow under the stock lights

I just added (2) lunar blue strips to my Biocube last night. I wanted them to help make my corals look better by adding a little more blue to the white and actinic. They are only $20 a piece so I figured it wasn't a huge waste.

My zoas do open up with only the LED's on. I don't know if they help with growth though.

So there are 4 open slots. One power button that is not being used.
I have one Blue LED now that came with the Cube.
I'm confused as to the 4 Open slots and what controls it?
There is one button that is not being used, is that one for the 4 open slots?

The first LED switch (left to right) controls the one LED bar that came with the aquarium (and supplies power to the second switch). The second switch controls the four expansion slots.

Since there is only one power cable for the LED's the first switch act as a main and has to be on for the second switch to work.

This is why I went with just adding blues as I didn't want whites on with my lunar lights.
