What's more beneficial for lps growth

I think you're underestimating how much your LPS is actually getting from that morning sun. I've got a similar setup with my tank catching some afternoon sun, and while it's nice, the par it adds is actually pretty low. I recall measuring it and it was only around 10, so not a huge difference. I'm guessing the window, screen, and tank's own filtration are filtering out most of it.

That picture of your LPS is incredible, by the way. You should totally enter it into some photo contests around here!

I'd say more whites than blues works better for LPS growth, in my experience. But to be honest, it's not just about the lighting - your alkalinity, calcium, and magnesium levels need to be consistently within range too.

I went back and re-read the original post, and I'm not seeing where the OP mentioned their current light settings. They just asked whether they should go with more blues or whites.

From my experience with the Reefbreeders, I've had the best results by keeping the blue channel at roughly double the white channel. I cap my blue channel at 90% and my white channel at 60%, but only for 5 hours a day, with a gradual ramp-up and ramp-down. These lights can be intense, so be careful not to overdo it – especially if you're using optics. I got rid of my optics and it made a huge difference.

I'm curious about chalices in an SPS tank. Will they thrive or should I choose one type over the other for a healthy tank?

I've got a 125g reef tank and I'm struggling to get my LPS to grow at the rate I want. They're growing, just not as fast as I'd like. My lighting setup is a Reefbreeders 48" LED, so I'm wondering what's the best approach - more whites or more blues?

My parameters are:
Ph 8.2
Alk 11dkh
Cal 440
Mag 1200
Temp 78

I've been trying to figure out the best lighting balance for my corals.

I've got a 125G, 6ft long - 48" light isn't gonna cut it, right?
