The light is a 13W 50/50 PC retrofit from an online dealer. It came stock w/ a 7W 7200K PClight that is just fine too, however I don't like the color of the light at all. I'm actually adding another 13W PC (from an AZOO galaxy light I took apart) to it, but this time it'll be an Actinic 03.
This was just your basic Red Sea Deco Art "betta" tank you can get at ***** for ~$30. It comes with a 16gph HOB and a 7W PC clip on light. I built a stand and retrofited the 13W to it, and tonight I built another (nicer) stand that will house 2 13Ws for it.
When I set it up, I added 1.3lbs of LR and ~1lb of fiji live sand.
I'll add soome pics w/ the new lighting tomorrow night. I'm all set to go, just need the bulb. This'll allow me to do the dusk/dawn effect. Right now the lighting is on a timer for about 6 hrs a day. I'll also try to get pics of the new buds from the PPEs. The frag of PPEs on the right of the tank will be moved to a 2.5 when I get it up and running. I'll probably then move the Caulastrea towards the front more.
Glad you like let me know if you set one of these up. I'd love to offer any help you need. These are really amazing tanks.
