spectrum

In today's video we get with Taras and continue our series talking about lighting. Today we dive into brightness, specifically dealing with PAR and how it affects our aquariums. We cover both how light intensity is measured in the hobby and go over some tips and pointers when thinking about...

Any solid experience opinions on AI Blade light configs for a mix tank? Coral types: Kryptonite Candy Cane Green Star Polyp Firework clove polyp Fall out zoa Florida Ricordea Sympodium (Maybe?) Favia Duncan Hammer

Does anyone that owns a SMATFARM 95w willing to share their spectrum? Or can give me a good recommendation on a good color spectrum for it?

I was under the impression that spectral changes occur in the oceans’ reefs as the sun rises, peaks, and sets. I mainly thought this was the case due to the atmospheric shift in color during sunrise and set. After watching a few in-depth BRS videos and reading some older articles from Orphek...

I have a Hipargero 100w 5 channel spectrum light for my aqueon standard 29 tank so it’s 18 inch tall the tank. I have mixed corals, torch, hammer, birdsnest, zoa, acan, gsp, Duncan… when I set up the light schedule, for the full ramp portion, I can choose the percentage of each color spectrum...

What's in a Metal Halide spectrum? What's the secret spectral sauce? How much UV does it really have? The answer greatly depends on the ratios of the halide salts used, the gasses, and whether the outer fused silica glass has been doped to absorb the UV from the mercury vapor discharge. With...

Take a look at the difference in the spectrums of the AI Prime Fuge and the AI Blade Fuge in the pictures below. The spectrum of the AI Prime Fuge is the REVERSE of the spectrum of the AI Blade Fuge. Has the AI team put ANY thought at all into the spectrums when designing these lights? There are...

Hi, I just bought the XR15 g5 pro and really prefer the daylight look instead of the very blue look. However, I can’t really find the recommended settings for this spectrum. I also dont know if its okay to just turn the royal blues and blues down regarding the health of the corals. I do like...

Hi reefers! I have 1 Ai 64 hydra hd + 1 red sea 90 light for my red sea 170 tank. Im planning to get another red sea 90 lights just to make the spectrum balance for my red sea 170 (60 x 50 x 50) tank. Do you think this light is overkill if I adjust all the spectrum by half? Limiting the...

So to start off, I am no expert in keeping reef tanks and I have only kept them for around a year. I have heard of people saying that they get very good growth from 6500k lighting but it really browns out the corals and of course is very unappealing. On the other hand, the majority say that a...

I have a tank filled with macro algae and corals. I’m wondering, does anyone know how to replicate full spectrum using the AI Prime 16HD? My spectrum settings are close to what bulkreefsupply recommends, but they are dialed back in intensity. However, my macro algaes started to die under this...

What does everyone have their AI spectrum settings at? Specifically for the AI prime. I’m still refining my schedule. At the moment the colors aren’t quite to my liking. I have calcified macro algae, softies, LPS, and easy SPS (birdsnest, pavona, stylophora)

So I currently have 2 zetlights 1201a https://www.bulkreefsupply.com/za-1201-aqua-system-series-pico-led-light-zetlight.html hook on to my 29 gallon reef tank, mostly low light lps and zoas what setting should i have set for optimal coral growth?

I lost my presets and have to recreate them for an LPS only tank. Two lights, 12" AWL looking for max PAR of 150 at the top of the rocks. While looking at the spectrum settings I found a horseshoe icon in the top right of the page. When you open it up there are two dial adjustments (see photo)...

I currently run the 20K BLV Nepturion 250W SE bulb over my tank. Couple of months ago I used to run the 14.5K Gisemann bulb. I have measured PAR from both and obviously the 20K bulb has less ( about 100) PAR when compared to the 14.5K bulb. Not too concerned about PAR, but I think growth is...

I've been thinking about dropping the color setting on my kessils to 0% with no change in intensity. Does this require acclimation, or is the transition fairly safe?

Fun announcement that's been in the works for several months... @Abhishek was able to introduce me to the fabled @Dana Riddle who some of you know as being something of a lighting leader in research with spectrum and par, MASNA Aquarist of the Year, as well as his involvement here on R2R. I'd...

Hey all, I currently run 2 hydra 26’s (with diffusers) using the BRS modified AB+ spectrum (about 54 watts of power) on a 4 bulb aquatic life T5 hybrid fixture with 2 ATI blue plus bulbs and 2 actinic bulbs mounted about 10 inches high on my 4ft 120 gallon sps dominated tank. I am about to get...

Hi, Ive got my first nano reef tank and am planning on having mainly softies with a few LPS. The tank is 40cm deep nano cube and I bought the new Spectra Aqua Knight v2 LED. It comes with three time settings each of which I can set the intensity of the three spectrums (Blue & Purple, White...

What Is The Right PAR For Vibrant Coral Coloration and Growth? NEW VIDEO! Reef Aquarium Lighting Guide

I want to know your spectrum and schedule regardless of what kind of light you have. If you can give all the details, spectrum, schedule, intensity and your results that would be great! I am currently running a Radion XR30w g4 PRO on the ab+ setting. I swear I was getting better growth using...

So I've had a lot of conversations with people regarding spectrums, T5 lights, what spectrums in T5 lights are responsible for making what colors pop, what spectrums in T5/MH fly under the radar. Also been reading threads from Dana Riddle where he claims Green spectrum is much more important...

I'm working with @James Emory (I believe) to pick out a custom arrangement of LEDs for two of their Orphek )R 120 light bars. I'm looking for something around the 25K look, the light bars will be over my frag tank and the health of the corals is very important. Each light bar has 36 - 3 watt...

I thought it would be worth noting a lighting change I made recently. In my Nuvo 40, I had been using a Masxpect Ethereal for lighting with the thought that the output it produced would be more than sufficient for a mixed reef in a tank that size. I will admit that I like my lighting to look a...

How many of us truly understand the importance of these measurements within lighting and our reef tanks? I produced a video 'hoping' to help those who dont quite understand it! - Hope you enjoy it :)
