Can This Light Grow Any Coral...At All?

ive read that red leds can actually exacerbate algae problems...not sure about the green

Yup. Red spectrum is what algaes like. Red should be run very low or not at all. It can also burn corals.

 

Green helps bring out the green in corals but not overly important.

 

Blues, violets, and UV are very important to corals. White helps with growth but doesn't need to be on all day or overly high percentage.

literally to a tee of what i have read!

What type of lighting fixture do you recommend and can you change the amount of color in par 38 bulbs (like the white listed below). If I use the abi bulbs, then I will not have to tone down the white because it only has one or two whites. I will probably go with the abi bulbs

Par38 bulbs are not controllable. Some can be dimmed. So it's best to choose a bulb in a spectrum you prefer. 

 

 

I have used 2 different par bulbs. Abi tuna blue and a no name one 50/50.

I personally preferred the tuna blue, better quality, better spread, and the colour spectrum I really liked. I had good growth with it as well.

 

There are many lights available depending on your budget and needs.

 

 

par38 bulbs- I listed the highly recommended ones in a previous post.

 

Aquamaxx nemolight

Current orbit

Kessil

Nanobox

Aqua illumination

Micmol

Radion

Hipargero

 

Do some research on lighting and then research the various options and choose one that meets your needs and budget.

Many of us have used the Abi tuna blue.

 

I had sps growing under 12watt tuna blue.

 

On a 20g that's long 2 23 watts are more than plenty.

 

Par38's are powerful.

 

 

The reason why the bar is a waste of money- you will need to buy appropriate lighting for corals, do it from the start.

You can buy far cheaper lights on Amazon for a fw tank like the nicrew.

What size tank was your tuna on? I want to put a 12 watt on a 8g biocube hoping to grow at least lps

I used it on my pico har, 5.5g, and 10g.

 

It really depends on dimensions

Doesn't look like it. Standard light, would work on low light plants.

 

There is no description of spectrum so its most likely 3700k-5000k.

 

The par is very low.

 

For the price there are far better options than this

 

 

I am curious what the par is for this light I have looked almost everywhere on the internet for anything on it. I use it on my planted 20g and grows my Anubias and amazon sword quite well. I was curious to apply it to my 10g reef tank being since I only have smaller Alveopora. Do you know of any places or sites that would have standard light fixure specs or spectrum or par. Thank you in advance

Just to chime in on some more annoying bad science.....

 

The Sun....that big ball of bright light in the the sky that's responsible for most life on earth has a color temp of 5500-6500k depending on time of day. No, the artificial  /  fractional spectrum bulbs in your reef tank that over emphasize 450-460nm blue to make corals look cool is not superior to the Sun when it comes to growing coral. Seriously....

 

Reef tanks will grow fine at 5500-6500k, and no, you will not get more algae growth. It just won't look good because we're used to seeing 99.99% of reef tanks lit with artificial lights that are 80-99% far blue light. Fresh water tanks tend to look aethestically fine at 5500-6500k.

 I totally agree with you but I was just wondering if anybody knew what the par or pur  rating for these light fixtures were or any light fixture for that matter. I am well aware that corals can grow in any spectrum of light long as it is equivalent to the sun. But what I do not want to do is over saturate my coral with par and pur. This article does a excellent job of breaking down the belief that we need just two spectrum for then to thrive. I don’t own a par meter and can’t test my lights to see the output and would like to know if mine are to much or I need more. https://www.advancedaquarist.com/2013/12/lighting
