Are these Seneye PAR readings correct?

JCOLE · Jul 21, 2020

My Seneye came in today and I set it up and ran some PAR readings while connected to a Laptop. My PUR stayed around and above 80% so that is good. However, around the top of my rock was showing 1500+ PAR, middle of the tank was around 1000-1200 and bottom of tank at sandbed level was around 500 PAR. I have a 150 gallon 24" deep SPS Acro dominant tank. All of my pieces have good color and good growth.

I have 4 Mars Aqua Black Boxes with upgraded LED's for better spectrum and (2) 80w ATI Blue+ t5's. I took these readings when everything was at 100% which I run peak for about 4 hours a day.

By the looks of your tank I'd say something is up with the seneye perhaps??

I had some Amazon black boxes that were putting out 900+par at 22inches so I'd believe it

If it is true then I dont understand how my needles in haystack isn't melting away at 1500 PAR.

Not complaining just hoping it's not bad out of the box.

Good point lol. I burned a lot of sps when I put up the black boxes on the frag tank, but to be fair the corals were used to about 250 par. You can always rent a par meter or see if anyone in your area has one to compare data, then go from there

Some corals can take 1000+ par, especially reef crest acros

That is true but Needles in haystack is a deep water smooth skin acro getting blasted with 1500 PAR. I don't think that is right. I will make a call to Seneye to confirm with them.
