I got a PAR meter!!! (1 Viewer)

[RGH69]

My Apogee MQ-200 came in today. So I started measuring the LED lighting in my BC29.

I took the following readings at 8 inches under water.

170 All four channels (1 Warm White, 2 Cool White and 1 Royal Blue)
35 Warm White Only
55 Cool White Only
27 Royal Blue Only
115 Cool White x 2 channels
94 Cool White and Warm White
157 Cool White x 2 channels and Warm White
86 Cool White and Royal Blue
63 Warm White and Royal Blue

At the sandbed (about 18") I get 91 with all four channels

There are no secondary optics so I was actually expecting lower numbers. Besides all of my corals have good growth.

For comparison my 90g tank has 4 VHO fluorescent lights and runs 196 at 8 inches and is 105 at the sandbed (about 23 inches).

My compact fluorescent fuge lamp puts out 106 PAR at the surface.

My ceiling fan light puts out 2 PAR. 8)

I expect much higher numbers on the LED's when I get secondary optics.

Comparisons. Up this geek's alley!

Nice i wish i had one...Im jealous! lol

What types of corals are you growing with those numbers?

 

[soymilk]

Can't wait til we see the numbers with the tighter optics. Keep us posted.

 

[RGH69]

What types of corals are you growing with those numbers?

Monti Cap, Green Slimer, Fire and Ice Digi and various soft corals. Oh and Bryopsis

The coveted bryopsis!

I think corals are a lot more adaptive than we give them credit for.

 

[RGH69]

Yes, after doing some research, I found that corals will adapt to lower oight levels by becoming more predatory.

humm what Par did you have those pom pom at?

 

[RGH69]

They were in the tank with VHO lighting (100-200PPFD)but I have them in all my tanks. They even grow in the shadows, but very slowly.

Ok I will turn them far away from my mh..
