you're building a \u003cstrong\u003eproper planted aquarium and want lighting to be one of the strengths of the setup\u003c\/strong\u003e, the WRGB II is one of the lights we'd be very comfortable recommending.\u003c\/p\u003e\n\u003cp\u003eThe colour rendition is a huge part of the appeal. Healthy green plants look richer, red plants become far more noticeable, and fish colours are transformed — showing their \u003cstrong\u003etrue, natural vibrancy in a way that standard aquarium lighting simply cannot achieve\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eBut the biggest mistake we see with powerful planted-tank lighting is using \u003cstrong\u003efar more light than the aquarium actually needs\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eDon't buy a WRGB II and assume you have to run it at 100% to get your money's worth.\u003c\/p\u003e\n\u003cp\u003eHaving extra output available is useful. It means you can tune the light to the aquarium rather than having a weak fixture permanently running flat out.\u003c\/p\u003e\n\u003cp\u003eFor a serious high-tech planted tank with CO₂, good fertilisation and demanding plants, we'd choose the \u003cstrong\u003eWRGB II over the B Series or WRGB II Slim\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eFor a straightforward low-tech aquarium with easy plants, we'd probably save some money and choose a lower-output Chihiros model instead.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Chihiros WRGB II suitable for beginner planted tanks?\u003c\/strong\u003e\u003cbr\u003eYes, but it's considerably more powerful and adjustable than many beginners actually need. Start at a lower intensity rather than immediately running it at maximum output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I control the light from my phone?\u003c\/strong\u003e\u003cbr\u003eYes. The WRGB II connects through Bluetooth to the My Chihiros app, where you can adjust brightness, RGB channels and lighting schedules.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need a separate timer?\u003c\/strong\u003e\u003cbr\u003eNo. Daily schedules, sunrise and sunset effects can be programmed through the My Chihiros app.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I adjust the red, green and blue channels separately?\u003c\/strong\u003e\u003cbr\u003eYes. The WRGB II allows individual adjustment of its red, green and blue channels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it good for red aquarium plants?\u003c\/strong\u003e\u003cbr\u003eYes. Strong RGB lighting and good colour rendition make the WRGB II particularly popular in aquascapes containing red plants. Successful red plant growth still depends on overall plant health, nutrients, CO₂ and suitable lighting intensity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it grow carpeting plants?\u003c\/strong\u003e\u003cbr\u003eThe WRGB II is designed for demanding planted aquariums and can provide substantial lighting output. Whether a carpet succeeds still depends on tank depth, CO₂, nutrients and the carpet species you're growing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWRGB II or WRGB II Slim?\u003c\/strong\u003e\u003cbr\u003eChoose the standard WRGB II when you want higher output or are running a more demanding planted tank. The Slim retains RGB colour and app control but Chihiros rates it at roughly 40–50% lower brightness performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWRGB II or B Series?\u003c\/strong\u003e\u003cbr\u003eThe B Series is an excellent-value option for easier and moderate planted aquariums. We'd step up to the WRGB II when you want significantly more control, stronger lighting capability and individually adjustable RGB channels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I run my WRGB II at 100%?\u003c\/strong\u003e\u003cbr\u003eNot automatically. Many aquariums don't require anywhere near maximum intensity. Start conservatively and increase the output based on plant growth and algae response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich WRGB II size do I need?\u003c\/strong\u003e\u003cbr\u003eStart by matching the model to your aquarium length — 45, 60, 90 or 120cm — then consider tank depth, width and plant requirements. Contact us if you're unsure. All the sizes come with stand-offs\/legs to allow for extra length.\u003c\/p\u003e","brand":"Simply Fish","offers":[{"title":"Chihiros WRGBII 45","offer_id":42130360139853,"sku":null,"price":369.99,"currency_code":"NZD","in_stock":true},{"title":"Chihiros WRGBII 60","offer_id":42130360172621,"sku":null,"price":442.99,"currency_code":"NZD","in_stock":true},{"title":"Chihiros WRGBII 90","offer_id":42130360205389,"sku":null,"price":598.99,"currency_code":"NZD","in_stock":false},{"title":"Chihiros WRGBII 120","offer_id":42130360238157,"sku":null,"price":775.99,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/2180\/0269\/files\/download-68_2a2348ec-4408-4e0e-bff8-842260ab511e.jpg?v=1758755168","url":"https:\/\/simplyfish.co.nz\/products\/chihiros-wrgbii","provider":"Simply Fish","version":"1.0","type":"link"}
