Xr15 g4 pro + reef brite xho k15 increase par?

[Sethm]

I’m currently running 2 xr15 g4 pros with diffusers on a 90g running the ab+ spectrum at 100%. I purchased the apogee 420 par meter when I was setting everything up and I’m only getting 150-180 par 10-12” below the waterline, which is my highest rock point. Needless to say I was a little disappointed with those numbers being that I want to grow some acros

On the eco smart web app it says I’m pulling around 136 watts.

So with the xho k15s it says they have 16 -3 watt leds = 48w of supplemental light.

Am I in the wrong to assume that adding one to each fixture ( 96w added total ) would get me into the 250-300 par range 10-12” deep in my tank?

I know your feeling. I just rented the 510 meter from BRS and my G4 XR15 at 8" below the water I got a max of 210 at 100% brightness in AB+
So i am getting rid of them and going with different lights that did better then radions for me in the past.

Yep not willing to shell out the money for xr30s and new rms mounts.

what did you use in the past?

My last tank I had an xr30 g2 pro. I made switch to the noopsyche k7 Il lights and had better success. I am doing it again. I wasn’t going to spend another 300 for a 3rd xr15. Ordered 3 noopsyche lights and was only 600 for all 3 so selling my reef link and when I sell my xr15 I will basically spent no money for more light. This is on my reefer 350.

I do like the Xr15s, I just need a little more juice.

Has anyone tried out the reef bright add on?

Did you map out the par throughout the tank and what's your tank dimensions? I've got a reefer 425/88 gallons (47" x 22.6" x 22") running two xr15 g4 pros and was thinking of ordering the BRS rental but it sounds like my results would be similar to yours as I'm running the ab+ spectrum (but on 50% at the moment, not 100%).

I haven’t but I can. I ordered the aquatic life hybrid fixture and plan on hooking it up Tuesday so I’ll bust out the par meter then.

BRS has some nice PAR breakdowns in this video on test tanks similar to ours. If I'm understanding the video correctly, near 100% on the AB+ setting will average 250ish PAR throughout with some hot spots towards the top.

I just purchased one for my hydra 32. Haven’t gotten the chance of checking out the par yet. But according brs it should add around 30-60 more par.
