what light to use?

[OU_Pilot]

I just bought a new 4g nano from finnex. Light fixture that came with it is a 20W 3U CF with two white U's and one blue U....I have been having some green free floating algae problems and I think that I need to get my spectrum to about 12-16k, maybe even 20. I'd really like to get an LED set up but have never dealt with them. I'm trying to create a big soft coral tank. Anemone with a black oscelaris and lots of zoas etc..

Lighting Suggestions?

Thanks!

Hi

Algae problems are two parts nutrients and lighting. Nutrients are the most common problem but if they in check, it could be your lighting.

There is a lot of talk about adding a warm or neutral white to a LED Fixture. Some believe that this will give you better growth. Based on the photosynthetic properties of the zooanthellae algae, we believe adding Neutral or Warm Whites will not grow coral better than a Cool White. In fact too much of this warmer spectrum may promote nuisance algae growth.

The nice thing about LEDs is you have full control of your spectrum. Generally two Royal Blue for every Premium Cool White will giv you 17-20K If you use a warmer Bin Cool White you may need a 3:1 ratio for 20K.

For you 4G Nano 6-8 XP LEDs will work fine.

It would be Ala Carte on our Website.

At this time we dont have a specific kit for 4G Nano tanks.

You will need the following:

-Heatsink
-Driver
-LEDs

Depending on if you intend to solder or go solderless you will need Thermal Paste or Adhesive and BJB connectors w screws or Solder.

Optics are recommended to reduce light spill.

Here is a link to one of our larger soldered builds that may help.
