nice bright tank. Just make sure you don't tell those guys you got 10,000k lights. There are still a lot of old school guys that do not like freshwater with 10,000k lights. Personally, I love it and think it looks way better. I use 10000k lights on one of my tank. I used Nova Extreme before. Theyr'e not a bad product and have proven to be reliable. Becareful using these lights for an extented period of time cuz you might get algae.
You got to get rid of that rock cave. I had an endli that develop scoleosis from it.
