LED Lighting Ratio?

[Jdavis8824]

I've had my tank running for 6 months now. My corals colors could be a lot better as they fade after I add them to my tank. It's mostly Lps frogspawn, zoas, Duncan's, birdsnest, mushrooms, ect. I've been using a ocean revive 120w T247. I usually have the blues 10-15% higher then the whites, greens, and reds. Is this the right way to do it or should I go more to 50/50? And how much par should I get it up too? I want to keep a few easier to keep sps eventually. Also I recently had a phosphate problem but I just added rowa in a reactor so that should be cleared up soon. But the colors of my corals started to fade even before the phosphate problem. My light is about 10 inches from the surface and now set at 20% spec 35% blues

I've barrowed a par meter once and got 500par at the top of my rocks with 250-300 on the sandbed. Never really got it that high though but close. That reading is at 45% blue, 40% specturm

Any suggestions?

Sorry, no suggestions. I'm interested as well. I have the same lights (3 over a standard 180) and am running them at 32 blues 20 full spectrum. From what I have read these are low levels for this light but I feel like if I turn my full spec. channel up let's say 20 -> 23 my anenome and a few corals start to expel zoo a few hours later

Yea that the par readings are pretty low at that percentage but my corals colors were fading at higher ones. Most LFS have almost nothing but blues on theirs. Wondering if I should go 40 blues and 20 spec

im running 2-1 ratio blue to white on those lights, my duncans are fine, but really i dont have enough coral to give any real advice, my percentages atm are 90-45, but my tank is 31" deep

My Duncan's are one of the corals not affected too. It's mostly my polyps that are affected. But I think I will go with a 1:2 - 1:3 ratio to see if it affects them any. May have to wait a while to see if they work. It's gonna take a couple weeks to rid my phosphates although I know that's not the problem for the color just the growth, because I had this problem before the phosphates. But now my phosphates are at .38 and going down.

And based off my par readings at that depth that's a lot of light. 45 blue 35 white read over 500 5-8 inches deep and 300 24 inches deep. Your running twice that and even though it's deeper it's still gotta be a bunch unless your running a sps tank

no, im not running sps...yet, but the par readings for the Arctic t247 from the manufacturer are 310 at 24" depth in the center of the fixture, so that has been the basis of my output percentage.

I dont have access to a par meter myself, and im using glass tops.
