I am very surprised. But that's good. Test it out put a frag in and see how it handles it.
So what should my lux reading be on the meter
min 25,000 lux at 8 in. as an estimate. not going to be much par available though i would guess. very iffy.
I will test it out when I get home from work an let you know what I find out. Thanks for the info and help. Will keep ya posted.
Probably anything around 15,000-20,000 lux would be OK, but anywhere between that and 50,000 lux would be pretty ideal. Up to 80,000 lux is accptable for most corals, but can be a cause of some oxidative stress too.
More light is not necessarily better - corals are low-light specialists, really - but you do have to satisfy their minimums. Their minimum is called thier "light compensation point"....where they get enough light to cover costs of metabolism. Aka "Enough light". Most corals seem to hit their compensation point somewhere around 5,000 lux, plus or minus a few K. More light than that is gravy!
Bonus article on corals adapting to low light and high light situations:
"Primary Production and Photoadaptation in Light- and Shade-Adapted Colonies..."
Oh, also, the table of lux values here should give some more perspective:
Samples are taken at the surface so it doesn't matter.
Great article. Thank you so much.
Jumping in on this thread.
My current set up is 2-1 royal blues to neutral white.
40 royal blues
20 neutral whites
These are spread out over 4 units.
Over a 180 gallon tank
Here is my tank
I run a storm controller with 6 dimmers
All leds were purchased from rapid.
I have debated adding Violet. Maybe another color
I believe I am turned up to about 75%
I have light defusion white from Home Depot over the tank to keep jumpers in the tank.
The grid is 18" above the tank.
Just bought a biotech parameter to measure light.
My corals open up. And grow. But not fast. Or nearly no growth.
Any advice will be welcomed.
Lights and flow and nutrients......and that's assuming your water chemistry is steady. Any variation there can stall things out and even make ugly.
