Platy - Thanks for the compliments! I actually use timers on this tank. DIY moonlight then about an hour later the LEDs come on then finally about an hour after that, the t5. The process is reversed at night with a bigger window for the LEDs by themselves. The dimness of those lights, especially after watching it with the t5 on, gives it a very cool quiet duskiness that is hard to describe. It is actually my favorite time to sit and look at the display. That's usually when I get inside the tank, mentally, and swim around with my buddies. I get emotionally recharged. Better than meditating. Narwhal - I think you might have a point about the plants. That hygro grows so fast! Maybe I'll trim it down some and see what kind of difference it makes.
