What PAR readings to you keep your SPS in?

Yeah Yeah
DML08 I am assuming you have a fiji purple in your fixture??? I have the same fixture and I was getting 550 under the fiji purple a few inches from the water surface but under the blue+ bulbs the par dropped to 400 at the same level.

No wonder I was having problems with coral coloring, everything seemed to lighten up when I would place it in my frag tank, turns out at the bottom of the frag tank was mid 600's and the top, just under water was mid 900's, so I raised the fixture as high as I could, now I am at mid 500's in the center. Hopefully that was the problem.

200-450 with my T5's
Smooth skin types like Hawkins, Red Dragon do best 200-250
Sweet spot for most is 350
Millis like the higher levels.

I know that this is kind of an old resurrected thread but do want to say -
WE ARE TOO PAR HUNGRY....but I think this is changing now...
Lighting power and nutrient export techniques have advanced too much and all our sps corals are getting pale.
This has been a trend from 2010-2015 - now most are catching on. Nothing needs over 200 PAR to look good, unless you run nitrate at 5 or more. If so - give your corals more.
Most reefers say "my Corals are brown, do I need more light?" No...your corals are light brown = too much light. I very rarely ever see a truly browned out coral now due to too little of light/excess nutrients - corals can go brown when pale - almost a tan - be mindful of this.
Less nutrients = run less PAR
More nutrients = run more PAR
Balance Light and Nutrients. People are giving their corals too much light, forcing upon them excessive growth, which leads to paleness or light brown corals as they can't feed themselves enough to keep up with the photosynthesis.
Rant over.
