Par acclimation regarding color temp

[John Neuzil]

I am currently renting a par meter from BRS. I timed the rental to coincide with a lighting change. I was running double strip current loop marine lights in a tank with a twelve inch depth. Settings we're 100% blue and 70% white. Green and red are 0. Par was 200 at top, 170 middle and 145 at the bottom.
Running a AI Hydra 26 HD and the BRS settings I'm seeing about the same. 230 top, 170 middle and 120 bottom.
The Hydra has more than just blue as you know with UV, Violet, Royal blue and blue.
With the additional colors should I be running an acclimation mode at all give the par readings are similar.
If so what do you recommend.

Thanks.

I would for a short time if you have switched from the strip to the hydra. Spectrum change will have an effect on the zooxanthellae. Slow transition is good.

Good job getting hold of a PAR meter. :) What are the percentages you're using with the Hydra? Those PAR intensities are so similar that very little acclimation should be necessary with the new light, although you might have to adjust the spectrum a bit. Seems like your white channel has been pretty high compared to many reef light setups so you may want to have your Hydra white channel a bit on the high side, at least at first. Generally you'll want to keep the blues, violet and uv channels all at similar intensities. If your red and green were off before then continuing keeping them off or at a low level perhaps 10%.

The ones from the BRS video.
118% UV
101% Violet
82% Royal blue
65% Blue
6% Green
5% Dark Red
19% White

You can rent par meters from BRS!?!? :eek:

Yep

Set the par to the old settings.
Hit acclimation. Let it run.

Also, write down the settings that give you 50 and 100 more par on the sand bed. Keep it for future use.

IMO. Buy a $16 lux meter and meter the top of the tank with the old light , the new light (at set levels) and the two future sets.

Great idea on the lux meter. Already have one. Thanks.

I'd up the Blue channel a bit myself; the rest look ok.

In your current situation, I'd adjust the white channel so that the resultant look is similar to what your old lights gave, at first. Then check the PAR again to see if any other initial adjustments are necessary, before returning the meter.
