Hello. I have the XR30 Gen 3 lights. I have had them for years and always just left the settings alone and inputted times. I do not understand how to change the presets to go with my tank. Is there an online tutorial? I have researched and looked everywhere. I do not understand how to make the changes and see what I have setup. I see the graph change but then I forget what I set each point to. Is there not a simple way to view the graph and what each point i set a preset to?
