Parwise

[miller75]

I have just been look at getting a Parwise, but whats stumped me is on their website under specifications https://www.par-wise.com/#tecnical-specification it says it reads between 1000 - 10000 Kelvin, now I know absolutely nothing about Par, kelvin etc but my Radion G4's do 20000 Kelvin so does that mean it want work properly because its only cable of read 50% of the Kelvin?

Not likely. It just won't "define" light above 10000K.

Par ect should be fine.
To be honest 10000k is a bit low.
Around 14000k is about where lights can be accurate.
Most "20000k" lights aren't 20000k or 20000CCT.

My PARwise and my Apogee MQ-510 read vastly different. PARwise tells me that Apogee reads UV light as PAR.

I just adjusted my light to the PARwise about a week ago. It was reading about 100 PAR lower than the Apogee. I think the PARwise might be more accurate as I have a Maricultured Red Planet Acropora that had a lot of green developing in it. I added light and adjusted and the green is leaving.

I wanted to update this as the situation progresses. I'm a little shocked. I adjusted my PAR based on the PARwise as I said above. It was about 100 PAR higher than the Apogee.

I went from about 300 PAR reading on the Apogee and adjusted to 300 on the PARwise. To be clear, this now reads approximately 400 on Apogee.

I was really concerned as Acropora aren't the best candidates for major PAR adjustments. It's been about 2 weeks since I adjusted and all of my frags and colonies are coloring up a bit and everything is doing very well.

I think it's too early for me to determine a complete success. I'll give it a few more weeks and report back.

with the 2 sensors reading so off i would suggest getting a 3rd meter to see which one is telling you the real story.

if the apogee sensor is off you can send it to them and they will recalibrate it for you , i send mine in every 2 years, i think it was like $50 to have it factory recalibratesd if i remember right.. its way cheaper than getting a new sensor.

Well, seeing as how I bought it brand new last year, I would sure hope it isn't off that bad. I appreciate the information.

I had been suspecting my PAR was off a bit ealirer as I have an ORA Grape Acro that has good growth, but the coloration was kind of brown to pink.

Now, it's coloring up and doing well.

I got a PARwise today and I am a really surprised with my readings. Directly under my XR15 G4's at about 10" running AB+ at 100% I am getting 72. Even about 1/2" under the water I only get 387

Ok, so maybe I can help with the settings as I was in the dark too. They have 0 instructions. There is a button that you click for out of water or in water readings.

Out of water is green leaves, what looks like a planted fresh water tank background.

Under water is a reef background. You will also see a little water drop beside your PAR reading. This is on the home screen before you switch to spectral analyzer.

Make sure that switch is correct then take readings.

But yes, this is what I was saying too. PAR is VASTLY different than an Apogee. However in my Acropora system, I adjusted to the PARwise and everything is doing great so far. Fingers crossed........

I did find the button after a few attempts! The trouble I have is the XR15's are on 100% already!!

Maybe I am misreading your post. How are you getting 72 outside the water, then you're getting 387 1/2" under the water?

Sorry its me not explaining myself properly, 10" under the water directly under one of the lights (So not off to the side) I am getting a par of 72

That might not be too far off. Depending on what corals you keep, might need to lower them a bit. Also test with flow off.

Lower the lights?

 

[Hurricane Aquatics]

Lower the lights?

What do you have in your tank, corals, etc? Also, what is the current situation and health of the corals?

 

[miller75]

Mostly LPS, torches and hammers. They aren't doing fantastic but they are ok which is why I tested the par. Typically I have the lights on the RMS mounts so I cant lower them

 

[Hurricane Aquatics]

There are many variables, what size tank, how many XR15's, what are your parameters, etc.

PAR is only a part of the story.

The measured spectral peak from your G4s is off. They peak between 447 and 450nm.

Sorry that doesn't mean any to me, does that imply the meter if faulty or the light?

It depends on how you have the sliders adjusted. If you had them all at 100% color for all channels, then it might be off. You would need intensity at 100% and all colors at 100% to see the true spectrum of the fixture.

You can set the spectrum with PARwise by adjusting the sliders. That maybe why your PAR is off too. What are all the color percentages at?

 

[Hurricane Aquatics]

The measured spectral peak from your G4s is off. They peak between 447 and 450nm.

Upon further examination, it looks to peak around 440nm. However again, color adjustment on the LEDs. He said he's running AB+ which means all his sliders are not all the way up.

You can raise the color adjustment until you peak about 450. I would go by the PARwise spectrum analyzer, not what someone told you.
