Led choice?

[yamaha racer]

So I have a cadlight 27w led light over a 10g. It's 9x3w LEDs, 5 royal blues and 4 white.
I'd like to change out a couple LEDs to blue, or something else. Should I just go white and blue or should I add red?
I'm pretty new with led.
This is what I got.
Thinking of adding 1 more blue and 1 red instead of the white.
Let me know

I wouldn't bother with the reds myself. The whites have a considerable amount of reds already but I would change out a couple for blue or even try to get 1 uv In there.

Depends what's in the 10g tank, if you have red/purple corals red could make them look a bit more vibrant. However the problem is if you put it on the same current as everything else it might be to red with no way of adjusting it. What you might do if you have the LEDs, is maybe just hold a red LED over the tank with everything else and see if it actually does anything.

And yeah depends upon the whites, cool white? neutral white? warm white? I would go with a warm white replacement rather than red myself.

I forgot to add the pictures





The tank has lps, sps, zoas, and will eventually have a rbta

Whites typically cover the red just fine.

Usually you get a mix of blue and royal blue -- more royal blue than blue though.

Since that light is 3 clusters of 3 leds I would probably not mess with it, might end up with it off balance.. Are the whites/blues independently dimmable?

No, they have individual switches but aren't dimmable.
2 clusters have 2 blues and one white, while one cluster has 1 blue and 2 white. Im not sure if the blues are royal blues or just blues. But id like to change the 2 white one blue to another blue. But if they are blues I'd like to change them to royal blues. And the whites to something softer, it's very bright over this tank.

A couple things to think about
1) adding a red to any cluster will absolutely make it a very red source, you really don't want to do that, if you look at something like the Radion pro, it has 2 red LEDs for ever 21 other colors and on top of that the reds are individually dimmable.

2) If you do an a blue LED you might have that LED is much stronger output than what is already on there so it could overpower the blue end.

Just something to think about.
