T5 Bulb Combo's Question

I've recently been lookin at different bulb combos. I like the blue look where the corals really POP! But is whats good for looks also good for growth? Currently im using Giesemann Aquablue + x2 and Actinic + x2
Color is ok the only thing that really pops though is my rainbow bta and some nuclear greens.
Here's a pic of my tank.

These are pictures of the look i'd rather have.


As far as corals go, i have zoas/palys , lsp, Rainbow bta , plan to add an sps or two. Softies too. So can i get this color without loosing growth? Please post pics of you tanks and what bulbs you use as well as how growth has been.

I use a Green Element LED 30w (that's 10 x 3 watt bulbs) light that has 7 x 10,000k and 3 x 460 actinics. I feel it is not blue enough and am thinking of buying a T5 fixture. If I do, I will trade out the 10,000k that it comes with for at least 14,000k bulbs, and keep the 460 actinics. Since the bulbs you listed don't have a k rating associated with them, I would say try some 20,000k bulbs and see if they 'blue out' the tank like you are hoping.

I don't have any recent pics of my tank, I just switched phones and haven't swapped photos yet...

I dont remember the k rating i'll see if they arent too hot to check
They are actinic+ 450 nm and aquablue+ 15,000K. the aquablues are white though

It's a blue-white, though?

Try 20,000k. They are definitely more blue than 15,000k.

Absolutely. 20,000k are just as bright as 10,000k, just a different color temperature. It is also said that some corals thrive off the 20,000k while others thrive at 10,000k. So it is going to depend on what you are growing...

How many bulbs is this fixture? Can you mix the bulbs and throw a 20,000k in front to blue out the tank a little better?

Maybe start with a 20,000k in front and see if that gives you the look you want. Keep corals back and under the 15,000k and maybe you can get the best of both worlds...
