WRGB color settings on a 4 channel light

[Sb1415]

This is an informative post. I was lead to believe by probably unreliable reading that the blue spectrum will result in Algae and i had it turned down to a minimum. But this was with a Fluval 3.0 which did not have the green spectrum just red, blue and shades of white. Curious if that is a myth and how it started. This post hopefully sets me up for success when i get the Chihros WRGB II

If you run hours and hours of blue moonlight, yes that can provide energy for algae growth yet is insufficient for plant growth.

Best bet, run your light at a suitable intensity for around 8 hours and dont run moonlight for hours…

But not running blue channel is just plain silly. If you are running white lights you have plenty of blue spectrum light in that mix…

As an aside, other than the app utility I think the fluval 3.0 is incredibly over rated…the color rendering is horrid. The red is pink and weak, the blue is an incredibly wierd blue.. true white pure white are incredibly weak. All power comes from warm white which has lots of yellow in it. The beam angle is quite narrow and low to waterline yielding lots of shadows and dark areas in the tank…. The contrast in looking at plants is awful…

But by golly there are lots of youtube presenters that think its the Bees Knees of aquarium lighting….

Yes. In my limited time with this hobby, i see there are fish tanks, planted fish tanks and aquascaping. Fluval 3.0 has high ratings in the planted fish tank community.

Which baffles me to no end.

Hi @Pepere I have two Chihiros WRGB 2 Pro 90's over a 225 gallon tank and below are the settings I'm using

As you can see I have a generous ramp-up/down built into the lighting schedule rather than just on/off....I've always liked the ability to simulate sunrise/sunset. The white channel is turned down since these lights are paired with some Fluval 3.0's

Hope this helps

Holy smokes..
I have the same light..the max I've ever set any colour is 80...at the moment 60...if I did 115..id be trimming every hour

But seriously how do you set it to such strength?

Depth of tank might well have something to do with it. Poster had it on a 225 gallon tank..

I have found though that you can raise intensity higher by doing it gradually over time allowing plants to acclimate to higher intensity in so far as algae avoidance.. but yes, plant growth and trimming needs can get to be a bit much..

225 males sense. I've got one on a 75.

Not to go too far off topic, but finding the balance between lushness and maintenance is something I'm playing with these days. Especially with travel.
