Hi all
I need help. I have a 120 gal reef. Which was previously lit by a solaris I4 until 1 of the 2 power supply's went bad. When it went it was 2 late to get another one. So I did not hesitate and got 2 t5 54 watt retro kits. For a total of 4 bulbs and I had 2 150 hqi halides laying around that I put on. All bulbs are brand new. Halides are 14 k ushio. The pendants themselve are different one is a coralife clamp on and the other is sunpak I believe. T5 's are on for 10 hours and halides are only on for 2 hrs. Its been 2 months and nothing is adjusting . 60 percent of the coraline has bleached. Everything closed 40 minutes after halides come on. I have stop using the halides for now and coraline is coming back slowly. I have asked around and the only thing I can think is maybe the protective glass on each is not uv rated.. does that sound right? anyone have a Idea?
