I use an old 150W Metal Halide now that I can sell Dragons Breath and Tongue faster than I can grow it and it helps to show it off, but screw in CFL always worked fine for me. In the BRS Infomercial, remember that this kind of light grew chaeto enough to remove the same amount of N and P as the more expensive lights. However, the expensive lights grew a mass that weighed more. ...but it had the same addition of food. ...so the only thing that could have made it weight more was extra water since there was no more nitrogen. Just focus on any of the lights in the Infomercial that got the N and P to zero in their tanks. The rest of this is purely academic and overthinking things.
If you have a red macro algea does it require a different spectrum then what traditional refugium lights produce???
@Ryanbrs can i ask you a silly question?
We speak about our fuge lights competing with our display lights, and we talk about our chaeto outcompeting gha or the like, following?
Well if we are running our fuge lights opposite our DT lights are they really competing? My immediate thought is, the DT light causes the algae in the tank to grow from 9am to 9pm, and then the fuge light is cauing the chaeto to grow from 9pm to 9am... should i really be taking this literally, or is something happening biologically that i am not considering?
Am i supposed to be thinking that my chaeto strips the water at night so there is less for the gha to uptake during the day? So its not an actual literal comparison you are making?
Looking for clarity, not arguing against you because this is exactly how my tank works, full of chaeto, no gha. im just trying to look a little further into it i guess. Help me!

Is there a simple way to know the ratio of when the refugium light outcompete the displaytank? Im currently setting up a redsea reefer 250, 55 gallon display full triton method with mostly australian acropora and some clams, my displaytank lightning is Philips Coralcare running quite high % due to the corals needs. How do i calculate some what near what size fuge light i need for my 16"w x 12"l x 10 depth refugium. It feels like a kessil h380 is too much, maybe a h150 is enough but not having had a refugium before and people grow algae from 10-300 watt i have no idea. Any help would be appreciated. What do @Ryanbrs or other pros have for ideas.
@BigJohnny currently uses this one and loves it. Grows chaeto like crazyI know this thread is fairly old but doesn't hurt to ask. I'm considering running this one on my current build. (10" x 8" refugium). anybody every seen this one or used it?

I have been following the brs series’ for quite some time now. I’ve had issues with nitrates, algae, and cyano for a long time. The cfl fuge bulb didn’t grow anything so i upgraded to the h80 and started dosing AF products to get everything under control.
I finally got my nitrates down to 2.5, the algae was gone, and the cyano was mostly gone (having siphoned out most of my sand over the 8 months to get that done).
I decided to try a modified triton method and do a monthly water change instead of weekly. I have cut back the amount of additives i was using to controll nitrates and phosphates in hopes the fuge would keep my levels down.
I am not having luck so far. Nitrates are over 10 after a couple months, the algae in the fuge (chaeto, grape calurepa, and a red macro) still doesn’t really grow, the algae and cyano in the display are back.
Any advice on what i might be doing wrong would be greatly appreciated.
