vbr aqua par meter new design sensor multiplier?

[Sleeperls]

Whatever version we are on now. I did some searching and there is a bit of info out there on the 2 older sensors. mine has the big eye and little eye. We using a multiplyer on these or no? Has anyone got to test one against another known meter? My tank is a im 50 lagoon with 30w 18d 16 inch tank height. lights are 2 xr 15 g6 pro mounted 8 inches off waterline. I am getting 180ish par 4-7 inches below waterline around 200 where they overlap in a small section. Just planning out my next move for the future. Ive got some sps frags in there now but to early to tell how things will go. Only been a week since frags where added but polyps are out and dancing. holding color for the most part. few browned out a little and that was to be expected.


Current schedule is the ab plus program at 80% so really only around 60% as the pro doesnt run everything full bore like the blue. 1:30 pm to 9:30 pm with couple hours of blue moonlight. The room tank is in gets zero sunlight or hardly any overhead room lights.


uv 100%
violet, royal, blue 100%
green, red, warm white, cool white 24%
peak intensity 100% unless on ramp up and ramp down using the stock ab + profile.

Being such a short tank im surprised as i was going off brs videos when researching the lights. I figured for sure 2 over this small of a tank would have been fine.

PAR meter aside for a minute..

G6 comes with a very wide lens. 126.3 degrees.
https://ecotechmarine.com/radionAt 8" a single led at 126.3 degrees produces a spot size of 31.6"
Par meter aside you are "wasting" lots of light front/back.
Put a white stick perpendicular to the tanks width and see how much light falls outside the tank.
"Optimum height is about 5" off the water line for a spot size of 18"

At 80 degrees spot is 18" diameter 9.5" from light face to water line. That would be a bit more ideal for the "narrow" lens.

2 is probably plenty for 35gals depending on goals, their height just isn't optimized.

Forgot to add I do have angled printed reef covers on them

Wonder the real world results on less angle lense. As cheap as they are it would be worth a shot of trying

I just recently bought the VBR-Aqua PAR meter with the new small and large sensor. I have never posted on a sight before but after doing hours and hours of research as I usually do I got frustrated with lots of different data so I decide to do my own testing. I used my friends Apogee MQ-510 for test comparison and turned off all pumps. Here are real world results:

MQ-510 186 + 144 + 238 + 198 + 216 + 170 = 1152
VBR-Aqua 132 + 105 + 170 + 139 + 156 + 122 = 824
——————————————————-
1.41 1.37 1.40 1.42 1.38 1.39 = 1.4 multiplier

Nice. Thanks for the post hopefully others can use the info as well.

Yes, thanks for this post!!! I too just got the newest VBR-Aqua with the small and large sensor and couldn't find anyone that calculated and shared the multiplier. On a whim just checked again and found your post. Awesome!
