Can you guys recommend a decent controllable light for the 4.8 gallon desk mate? I want to do a small pico in it with maybe some star polyps and one fish for my son's room, and while the light it comes with is fine, it isn't controllable and I'd like to simulate dusk and down and have a nice night mode for him. I just don't want to break the bank because I'm not going to grow anything challenging so stuff like an AI would be overkill. I thought about a kessil a80 but after the cost of the controller it way too much money for a simple setup. I appreciate any recommendations. Thanks!
