    Posted: January 26 2015 at 11:17am
I was curious to see if anybody has a PAR meter along with an hour or so of time that they could spare to come help me with the placement of my LPS corals. I'm running a Kessil A160 with a spectral controller on a 20 gallon IM Fusion aquarium.

Any help would greatly be appreciated! I'm willing to compensate

I have one for sale...unfortunately I don't have time to spare. PAR isn't the best measurement for LED lighting; PUR is better...but that's pricier.

I have both, but really difficult to advise. I could give you numbers, but but sure what to do with numbers.

When I lived in Idaho the reef club/society there owned a PAR meter that you could check-out.  

That seemed like a good idea.

Pete your hyperlink just goes back to this post?

I have recently done some checking of the light in my tanks and was very surprised at the low PAR readings. I got readings of 100-400 with an old Apogee meter. Yet, depending on the coral, it is growing very fast. 

The Par reading at this location and time of year is about 2000 in direct sunlight. That's the number I get when I hold the meter in direct sunlight outside, so the meter seems to be reading correctly.

There is a chart on the Apogee website showing the adjustment for different light sources, such as LED's.

Thanks for the articles Pete Moss & AcroNem. I will definitely read through them!

Do you guys think my Kessil light will be adequate for LPS growth in my 20 gallon?

LPS are typically deeper water corals. They love dim blue light, as that is often all that reaches them in the wild. Of course there are exceptions to every case, but generally LPS have no problems with lower light. I see no problem with your light being adequate for LPS, especially if they are being fed and water chemistry is on par.

If anything it may be too bright for certain LPS species. Acans in particular morph to reds and oranges when the lighting is too bright. Luckily it can all be adjusted in your case. 

My own DIY LED fixture is very comparable to the kessil, with the exception that I have so much UV I could blind my brother in his sleep. I run it over my 34 gallon and have to turn it down to about 35% of it's potential or my LPS corals start morphing away from their rainbow coloration.

I run blues 80%, whites 30%, UV 15%. I have 18 blue chips total, 18 white chips total, and 18 uv chips total.

I believe the kessil you referenced has 28 chips total.

Long story short, LPS in general loves blue, doesn't like tons of white, and appreciates moderate amounts of UV-A ( 320nm~420nm )
