How to Set Light Intensity?

[Administrator]

According to you guys feedback we have summarized some points of light intensity settings.​

There are many factors to be considered in light settings, which should be comprehensively considered according to tank size, the type and status of aquatic plants, Co2, and substrate fertility...

For example, in the early stage of a planted tank, the aquatic plants have not yet adapted to the new environment (including water quality, substrate, whether to use tap water, etc.), so the light intensity setting should not exceed 30%, which will help plants quickly adapt to the environment. If the light intensity is too high, algae will bloom, and the growth of algae will affect the growth of plants.

When the plants grow normally, if there is Co2 in the tank, it is recommended to set 50%-90% (if there are more shade-loving plants, it is recommended to set 50%-60%, and half shade-loving plants and half sun plants, it is recommended to set 60%-70%, and there are more sun plants, it is recommended to set 80%-90%); If there is no Co2, it is recommended to set 50%-70%, which can reduce the growth of algae.

As for color settings, it can be set according to the color of the plants. If there are more red plants, the red channel can be larger, and if there are more green plants, the green channel can be larger (Tank with more green plants will render to reddish by adding appropriate red channel). It is recommended to directly select the preset mode in our app like 'Red' or 'Buce' mode or fine-tune the preset mode according to your own preferences.

In brief, raising the aquatic plants first in the early stage, and then considering colors in the later stage, otherwise it will be easy to bloom algae.

Hi thanks for the info.
Could you also share how do we set to 60% pictures of the app will be good.
Also some explanation on the current app different preset setting.

I have 2 x chihiros light.
30cm wrgb 2 slim on a 30cm tank. Default green setting
45cm wrgb 2 slim on a 45cm tank. Default green setting

Both on for 6 hours a day with same setting and both running co2 .
My 30cm tank is beautiful.
My 45cm tank started growing hair algae.

After much check and test, I assume should be its a new tank setup thus my light intense might be too strong.

Would appreciate if you could provide some picture of the apps with the setting.

Everyone's tank is different, the water, substrates, plants, CO2, fertilizer...So we can only recommend the preset mode that tested in our lab, they are good for a mature tank you can adjust slightly to get better color rendering.

Hi
Ok about the red and green color but what about the blue?
I am using a wrgb II and i have noticed that if i use preset 70% and temperature of 7500K the alge is growing but if i reduce the blue color i can reduce algea. So my question is how i have to adjust the light?
Thanks
Regards George

Use the preset mode you can adjust it slightly by +- 5%.
If you just planted your tank donot use preset mode.

Are the recommended percentage values calculated from the light's max output watts? In other words, you would use the watts reported by the Chihiros app as the guide.

For example, on my WRGBII 30 Pro I like to set blue and green to only halfway of red and white. The 30 Pro outputs 37W max. Let's say I want to remain within the recommended range of 50-90%.

So, for the recommended 50% value (~19.5W) my settings would be:
R: 72
G: 36
B: 36
W: 72

And similarly, the recommended 90% would result in (~33W):
R: 120
G: 60
B: 60
W: 120

I'm confused if my reasoning is correct, because in my examples the R and W percentage values are obviously way higher than 50% or 90%.

Also, what I assume might complicate the calculations a bit is that the different colors output watts differently. 100% of green (others being at zero) reads 17W in the app, whereas 100% of blue only 9%.

The recommend percentage is the whole intensity. You can adjust the RGB percentages slightly.

How long would run them for on a no CO2 setup based on these settings?

6-8h

I am using WRGB slim II 45 on a 60×40×40 cm tank. It is newly planted high tech tank with fore ground carpet plants some green and red plants in the background. What light intensity should I start with ?
I read that the recommendation for WRGB pro is to start around 30% but does that apply to the WRGB slim II ?

We recommend start at 20%-30%, it depends on tank size and light size and many other factors.
For your 60×40×40cm tank with WRGB II Slim 45 light you can start at 30%.

Hi Admin, thank you for the detailed explanation. I'm setting up a new planted tank. Tank size is 45x45x45 (90L) background is covered by 4 inch aqua soil. I don't use CO2. I bought your Slim WRGB 2 - 45cm light. I'm configuring it now. As you mentioned I will set that to 30% for now. What about white color and the intensity below. I'm quite confused by those 2 settings. RGB I will set at 30% the other 2 can share the recommended values? I have quite a lot of green plants like amazon sword as well as 4-5 red plants. In this case which one is the perfect setting for now? also for the first few week can i run the light for like 6 hrs daily?

Hi guys,

Two weeks ago, I bought a Chihiros WRGB2 10th Edition, and I really don't know how to set it up.

I have an aquarium with the following specifications: 80L x 35W x 40H, and I have a CO2 system installed. The aquarium has plants, shrimp, and fish.

Currently, I'm dealing with an algae problem. I've removed 90% of the plants from aquarium and started a SEBA treatment to combat it.

At the moment, I'm using the auto settings for Sunrise - Sunset. I'm not sure what the ramp time should be or what intensity I should use for Red, Blue, Green, or White...

Can someone help me, please?

Thank you!

6h is fine.
White color and the intensity below are the Overall Brightness and Kelvin. You can only set either the above RGB settings ot the below 2, cannot set them together.
If you set well the above RGB, the below 2 will be calculated automatically in back data just not show.

Thank you!

WRGB2 10th Edition 60?
80x35x40cm tank, this 60 light is suitable.
Recommend starting at 20% intensity, add 5% each week for the growth. 10th edition is strong, you can use 60%-80% or find the more suitable settings for your mature tank.
0.5-1h for ramping time when you set 6-8h time period.

Hi Admin,
-Tank 80Lx40Hx35D
-Aqua soil Chihiros
-CO2 2 drop x second
-WRGB2 60 10th edition set at: Intensity mode buce at 25%aprox R20 G16 B25
-1 week planted
-6 hours with ramping of 0.5
Plants: rotala 6 varieties, Ludwigia 5 varieties, and hemianthus Callitrichoides Cuba, almost all plants are high requirements

I have this 2 questions, so thank you for your help

What light intensity recommend me to increase per week and what increase of period of time? To reach a what final valor of time and intensity? According to the plants

I have the hanging kit for the lamp, what distance from top of water surface to the lamp will you recommend me to lift it?

Thank you!!

Hi,
Recommend 15-30cm from light to water surface.

As for light setting, recommend adding 5% each week, 6-8h time period.
End at 60%-80% when it's mature.
When you cut and replant, plant densely, you can add percentages slightly.

Hi there, I just setup my mine today. Probably the best light I've ever owned so far in this beautiful hobby.

So any advice on this impressive light would be great..

From reading the forums here and this thread. I just want to ask if my settings are ok.

Day 2, full water change.

100 x 45 x 45 Tank.
Co2
ADA Aqua Soil Amazonia Ver 2
Forest Style Nature scape that climbs greatly to the back with lots of drift wood etc.

I've Marsilea crenata on the bottom,

Lobelia cardinalis on bottom and top with Christmas moss on top and weeping moss across the branches.

Schismatoglottis prietoi located on mid and top.

Bolbitis-heudelotii at the top back

I've everything set @ 30% for 6 hours a day. Do you think this is ok or too strong ? I would like to make sure I start off as low as possible but also to give the plants a chance and not grow Algae and get myself in a mess with the new startup tank. Again, I've never used this type of light before and it's also my first Aquascape so I'm nervous.

I've included pictures so you can get a idea of my wording above.

Thanks for the help !

Hello!
You use WRGB II Pro 90 on 100x45x45cm tank? Usually a WRGB II 90 light is enough for that tank size.
Pro version light is strong for your tank size, and the number of plants is small. To avoid brown algae, personally suggest to low the 30% light intensity below 20%.
6 hour is okay for current stage.

 

[W0oDe]

Thanks for your reply ! Yes I bought it because I know later on, I can use it on other tanks etc. At least I know it will deliver the light to the bottom plants without issues on this Scape especially after I hang the light from the ceiling. I am just waiting on the hanging kit to arrive. I had bad lights in the past and didn't want to cheap out on this tank build.

There's not much plants in there as I have some more coming ! I will correct this to below 20% now. Thank you for your assistance !
