We recommend 40 to 50% brightness on "green" setting to bring out the green depth of the Monte Carlo, 6 to 8 hours a day. Anything brighter you will end up with algae problems since it's a 1 plant aquascape. Make sure the CO2 is on at least 1.5 hours before the lights go on and have the CO2 turn off 1.5 hours before the lights turn off. Hope this helps you with your new Chihiros WRGB II 'SLIM'.

@@NORIaquaCh thank you for the feedback! Green light setting is ok also in the growing phase? The monte carlo is freshly planted. Co2 i have, but it doesnt have a timer.. well i just have to manually do that :) Anyway, what could happen if co2 is on all day?

@@didnthurt4077 Green is the optimal setting for Monte Carlo ☝️ CO2 needs to be on at least 1 hour before lights are on and 1 hour before lights are off. This is because plants release CO2 once lights are off, and if your CO2 continues throughout the night you will experience algae problems. We recommend a CO2 solenoid on a timer to best control your a CO2 ☝️

@@NORIaquaCh do you know any timer device that works with the ada co2 system? Was looking around and dont seem to find anything thats compatible. I use everything ada so i really want to keep my ada system. Thanks!

@@didnthurt4077 You can look at the ADA NA CO2 timer ☝️ www.adana.co.jp/en/contents/products/na_co2/detail06.html

You are welcome 👍

I had that problem too. Turns out it's due to a Potassium deficiency. I fixed mine by dosing Potassium

You are welcome 🙂 This bracket will be compatible for aquariums up to 90cm if you mount it from the rear cabinet. Make sure you offset the mount a bit, then extend the upper arm pole. If you have 2 lights you can install one on each end of the cabinet.

After 3 months I haven't noticed any notable light bleed on the SLIM version. The good news is that Chihiros makes a 30cm version that fits 30w (cm) tanks. The only complaint I have is their half baked Bluetooth enabled app, it needs refining and I haven't seen any app updates since getting the light. For example, if you have a power outage, or you switch off and back on the light, it won't actually turn back on to it's default state. You'll need to manually take your phone and stand in close proximity to allow the app to find the Bluetooth controller. A bit of a hassle, other than that it's a good light for the price point ✅ Thanks Ben.

@@NORIaquaCh I don’t recall experiencing those issues myself with the app, the only issue i know of is how you mustn’t disturb the connection whilst the app is in use. EG: moving around too much or letting the phone go into sleep mode. Else you get a connection lost message and have to reload the app. It happens more often if the Bluetooth controller is hidden behind the cabinet. So I suggest maybe try improving the line of sight to get a better connection? Fortunately Chihiros say the app is getting a big upgrade soon, I’m assuming to coincide with the new wrgb 2 pro model. Perhaps It fixes your Bluetooth connection errors? The wrgb 2 pro has an improved Bluetooth controller among other improvements, but doesn’t currently have Kelvin adjustment. I’ve disabled auto update on my iPhone, just in case we lose that feature. So I recommend you update at your discretion. I’m waiting to see what others say about it. Lastly, with my wrgb 2 60 what I meant about light bleed / glare is how it floods the room / walls if you’re ambient lighting isn’t also super bright. It’s a bit odd to have your furniture so saturated 😆 Which is why I thought the slim might be better as it has 2 rows of chips rather than 3.

Does it pickup the light on any other device?

The 60cm variant should work fine for a 70cm tank, as it has expandable legs. It has proven to be very effective for our tanks for all plants, and carpeting plants have done well using this light.

i use a 45 cm slim for 60x36x36, hanging. Works well for my plants

If your tank is 120cm then you can get the 120cm version.

It's normal, as they have used cheap components in the power supply which emits a high-pitched frequency sound. Mine is in a cabinet so I don't notice it as much 😂

@@NORIaquaCh Alright lol, thanks for the fast reply. These kind of sounds irritate me a lot even when quiet. I think I'll return it for a twinstar light instead. Do you know if they are quiet? Or recommend a light for a 60p (200USD price limit) 🫶

Go into the My Chihiros app, select your light and you can either add Auto setting or Manual setting. Slide Red Green Blue all to 70%.

This light is suitable for all plant layouts, however, if you want to only illuminate, say the middle of the tank, then this light isn't for you.

@@NORIaquaCh Cool! Im actually gonna plant all of the tank's area so i guess this light would be great for my heavily planted 60p, Thank you!

Make sure you enter in the NABAPLC 2022 👍

It depends on the actual colour of the plants (and fish) inside your aquarium. I usually leave it on default, which is 70% red, green and blue. However. if you have a lot of green plants with non-red fish, launch the "My Chihiros" app , select "Green". If you have green plants with red/yellow-ish fish, select the "Fish" setting. If your tank has lots of pink, purple or red plants and red-ish fish, you can select the "Red" option.

@@NORIaquaCh ok thanks. Im afraid of the default being too strong for a low tech setup

@@danialroslan1531 For low-tech tank, I would dial it down to 40 to 50%, this way if you experience algae, you won't have to clean up the mess and fix it. :)

It would be a good investment for future uses if you plan to reuse equipment in future. For low tech you can simply lower the brightness with this light to suit requirements of a low tech setup ☺️

For 90cm tank, please purchase the Chihiros SLIM WRGB II 90cm LED Light.

I have this light. In the beginning it worked perfectly. After 6 months DEAD. The green indicator on the power block is on, but the light does not come on anymore. Also the App cannot find any bluetooth coming from the light. I have not touched the light. It was working perfectly for 6 months. Until 1 day it just stopped working. Tried contacting the store where I bought it, but they won't help, because after 6 months, they don't have to. So now I have to buy a new light. I love the WRGB 2 (the full version..), but I'm scared, it's just money down the drain again, so will probably go with another brand. My tank is 90*50*50cm

@@A.N.Z. I have had the same issue. The fix was simple, but finding the solution was difficult. Clear data and cache of the My Chihiros app, then go into the app permissions, then allow My Chihiros to access your location. The app works as expected.

@@NORIaquaCh I will try this. But the problem is not just bluetooth control. When I plug in the power, the light does not turn on. But I will try your advice. It could be the solution. Thank you

That was the case with mine. The LED did not turn on when plugged in with power confirmed as per the light indicator on the power brick/adaptor.

Chihiros WRGBII SLIM 45 è da 35W e ha un flusso luminoso di 1.800 Lumen, mentre Twinstar 450ES è inferiore a 22W e ha un flusso luminoso di 1.600 lumen. Ottieni Chihiros per il controllo delle app o Twinstar per LED a spettro completo.

@@NORIaquaCh tu prenderesti la chihiros 45 slim?

Sì, per il controllo delle app sul telefono. ☺️

Yes, it would be fine for your tank size.

@@NORIaquaChcan this be used on a tank with a rim?

Absolutely, the light legs accommodate rimmed tanks too.

This light has grown both HC Cuba and Glossostigma very well ☝️

@@NORIaquaCh I have 55cm deep tank with an existing 40w light and was thinking of adding this light (90cm) version to improve the carpeting of plants like Monte Carlo. Do you think it would work ok for this? I use co2 and regularly fertilise also.

You may experience algae growth with two lights, the only way you can control it is to use one light only, e.g., use the 40w light or the new one.

@@NORIaquaCh well, both lights have the ability to adjust the power, and brightness, so surely that should help?

Using the 40 W light on its own I can clearly see my carpet in plants aren’t happy as it’s not enough

Good question, the SLIM version has all the control with the Bluetooth functionality but has a reduced output capacity when compared to the WRGB II Series by approx 40-50% brightness.

My tank is 9 inches deep, and I’m looking to buy the slim 30cm, will it be bright enough for demanding plants, I’m worried it won’t be bright enough even though my tank is only 9 inches deep, can I find a par chart for this light?

Not sure about the PAR chart for the light, but this light in the 30cm version should be fine for your setup. If anything just dial down the brightness to suit your needs.

@@guineapig6582 i think either one is overkill on full blast tbh, i got the wrgb2 in a couple of weeks ago , its way too much.

@@NORIaquaCh can it give me high enough intesity for rotala macrandra to turn deep red?

It is called Ember Tetra 👍

02:29 😢 Salam brother Im sorry to hear that.Leave it more to dry and then try.

It should be fine after 24 hours. Just dry it as much as possible with a towel and air-dry the light.

This might be the best backhanded compliment I've ever seen 🤣
