Well I think I boiled most everything........

Over the weekend the chiller started smoking like a chimney. Luckily I was at home or this coulda been a lot worse. Some of the wires had melted down to nothing but the copper on the inside. OK I shut that off, stopped the pump to it. and did all that to shut it off. Then like an idiot

I forgot the guy I bought it from installed the light upgrade so I get home from work Monday and the tank is around 97 and everything is shrunk beyond belief. So I tore the light fixture out. and did a water change to bring the temp down. This morning the temp was around 85ish corals are all still tiny but I think alive and one of my prides, the brain (which my clown ahd hosted with) is hard as a rock and it's soft green spaces are what look like disentigrating.
Not a good morning
Other than just venting my actuall question is this. When I got it the tank had three lights running, he said he upgraded it. well now I've only got 2. I know to use the all blue one, as for the other do I use the dual white, or the white/blue tube?
