Got 2 evergrow China boxes I believe 165w each, I recently lowered the intensity by 20% and raised the lights from 6" to 12" above water. So my light intensity never goes above 50%how much light do you have in there?
Yes flow shouldn't be the issue even though I've even trying playing with that, by dslr u mean a camera?if you have a lux meter or dslr I can tell you more on the light needs and if its correct.
I assume youve addressed flow?
low to med turb. up to right where you can see the fringe rustle.
So I should take photo of light at certain distance? Now would my shutter speed and etc alter my resultsyup, dslr.
my zoas more often wont open to flow than anything else. I also got some palys that I didnt know I had until I put them in my other tank that has twice as much light.
problem with lights now, is they say A lot a little or high low. with no actual quantitative number. except PAR. lux is a component of PAR. Intensity. the other component is color and spectrum.
a par meter is 300 buck a lux is $20 A dslr uses intensity. by using a photo that is well exposed I can determine how much light you have because I know how many foot candles/lux (intensity)it takes to expose at any given asa.
so 50% on a 165 w Chinese doesn't really say much. if your only really giving them 180lux
nope. Take a picture of your corals. note the asa/iso the shutter speed and aperture.
you can also take a picture of your flat hand at the waters surface and do the same. that will help me check my math.
I need the shutter etc to calculate.

I can try retake hold onthe quick answer is about 1300 lux. my hi lite tank is 20,000lux my low light is 12,000- 15,000lux
this is at +/- at 0the quick answer is about 1300 lux. my hi lite tank is 20,000lux my low light is 12,000- 15,000lux
