Hello admin, im a new chihiros user. I use chihiros wrgb 2 45 to my tank with the 50x28x33 cm size. Wanna ask about the setting of the apps, i wondering about the two setting below the RGB percentage, i slide the “kelvin” option and save it, but after i save it, the kelvin slider back to 3000k. Is it normal? And i put hairgrass into the tank, what is the light recommendation? Thankyou admin
