Photone App Blue and UV - Too low par

[PachoGinetai]

Hey community,

I have a question. I tried the photone app on a normal 29 gallon tank. For a new project I installed a Maxspect 420, with 120° Lens kit.

First I tried the par directly on the water surface ( above).

Channel 1 white on 100% = 680 par, should be ok
Channel 2 Blue and UV on 100% = 220 par

I think that is not correct. Ive read on the Internet from other users that with only 100% blue and UV they have above 100 par at 40cm deepnes.

So I measured on 40cm water deepnes 45 par.

So my question, can it be that the Maxspect 420 had wavelenghts that the photone app cannont measure?

Thank you for your help ✌

The only way to know for certain is with an actual PAR probe.

Blue doesn't produce the amount of PAR that White does. Most all of your PAR comes from the white LED's. I wouldn't recommend following that Photone app and get a good PAR meter if possible.

I came across that app you can convert blue light LuX into PAR. Which should give you some what close to what you are looking for
