Another important lesson in color temperature: Warm colors will advance in the painting and funky colors recede. One is that they are high intensity bulbs, but produce very little heat. They may worry that they will lose their job, their home or their life's savings. For a sparely planted aquarium, I like to recommend 1.5w of sunshine per gallon (1gal ~ 3.8L). Find your wholeness an individual find eternal wellness.
