In the SPS thread I was told my coral might not be growing from photo inhibition.
Is this too high?

Thanks. I also read "Too Much Light".How Much Light?! Analyses of Selected Shallow Water Invertebrates' Light Requirements - Reefs.com

Great article. There is still so much we dont know. Thanks to articles like this we keep putting the pieces together one article at a time.How Much Light?! Analyses of Selected Shallow Water Invertebrates' Light Requirements - Reefs.com

The deepwater acropora tables only that article taken from the submersible are simply amazing! I wish they were a little better.
I don’t really think we have to worry about the topic of too much light in our tanks. Unless your talking about how long your running the light. Past 6 hours at full intensity I don’t think anyone will see any differences.
Op you should turn your pumps off so the water is flat when your taking par readings. What kind of light are you using?
My Ballasts are digital and have a knob that goes down to 250. I should ask Hamilton Lighting....Can you swap out for 250 watt bulbs?
I would be interested in determining the clades that are present in my system OR finding a way to diversify the clades in my system that way the coral have options if they choose to dump one clade for another.The challenge here is not knowing what zoox clades are present in the OP’s acropora colonies and frags. So applying photo saturation thresholds of porites lobata to the acropora species in question may be about as helpful as comparing it to that of a tomato plant. I exited the game of ornamental aquatic plants years ago but the same could be said about any variety of those as well.
Thank you. Very helpful.This was the PAR in my 75 when I was running 250 watt Radiums. Main photo period was 7.5 hours. The corals at the surface were surely in PAR pushing 900 but they grew into that lighting level from 500 to 700 levels from frags. Unless the coral frags were grown in that high of par under metal halides, I would acclimate the corals slowly by starting them lower and moving upward.
They should be fine as far as lighting goes after they get used to the intensity and type of lighting. Lots of vendors are growing under LED now. I have first hand experience of assuming that you can just stick an acro under a similar PAR of a different type of light from when I switched from MH to LED the first time. Some will tolerate it and some will bleach, go dormant and/or die.
How long did that take to grow out?This was the PAR in my 75 when I was running 250 watt Radiums. Main photo period was 7.5 hours.

Nice. I need patience. LolThat was about 4 years of growth from frags to what you see there.
