OcalaReefGirl March 9, 2014 Share March 9, 2014 Ok, I know that spectrum is probably more important that just PAR, but I have found numbers ALL over the place for what amount of PAR you need for your corals from 125-500 for SPS. What do you keep your PAR at? Any consensus on the numbers or ranges for best growth for soft, LPS or SPS? Link to comment Share on other sites More sharing options...
dread240 March 9, 2014 Share March 9, 2014 It's fully dependent on what lighting you run... My LED light, with everything focused in the spectrums they wanted previously, absolutely cooked stuff while only measuring 200 par. I haven't gotten the par meter in our club yet to see where I'm sitting at now, but I've since dropped my DIY led fixture all the way down to 40% and it's the only way I can keep from killing stuff with too much light Link to comment Share on other sites More sharing options...
