Can't keep certain coral...need help!

[saltyfilmfolks]

On lighting. $15 lux meter from Amazon. Yes I can pretty effectively calculate par from that.
65% of what. At what distance.
Fwiw my frogspawn prefer more blue. I have the same approximate intensity in both tanks one is more blue. I moved it to the blue tank. It's happy now.

Are corals browning and rtn? Or fade slightly and rtn. I'd go with long ten lack of flow. That's my stick killin experience.

My chemistry is pretty off right now but stable. But I've lost some in that time from flow problems. (Jaebo) so likely a one two punch.

The lights are mounted about 10" above the water line. At full ramp, my lighting is at 55% intensity with UV, Blue and royal blue at 100%, whites at 24% and green and red at 10%. I am running the Coral Lab program.

Very blue. nice combination. prob 24oo kelvin. Ill assume a blue to White blue ramp.
I with few clues but experience would est 28 to 38000 lux (6-700 par???)at the top of the tank. that said you do have room to increase intensity IMO. Also cooler spectrum 14 -1600 kelvin IF you chose. Id go overall intensity first. Same spectrum.
if you lux meter it, go up 25000 5000 lux (50 - 100 par) every week for good accimation.

ow much should I increase the intensity?

ow much should I increase the intensity?

honestly, without owning a meter. I couldnt tell you. IMO its a parameter that should be tested and tracked like all the others for exactly this kind of reason.
$15 on amazon. Heres how I do it.

Do you get good results with that meter?

yes. very accurate. In the thread I side by side compare it to my $500 lab calibrated meter.
