I have a 55g reef.. I was faced with the need to completely re-lamp my coralife 4x65w PC
fixture because it was time to do so and I opted to buy 2 coralife T5 fixtures instead.. one is a 36" 42 watt and the other is a 30" 36 watt. They each have one 10k and one Actinic bulb.
My xenia, zoos and mushrooms don't seem to have any problem with the new lighting.. it seems a lot more blue than the pc
's and I'm told this is to be expected. I just need to know if I need more wattage.. next coral to be added is an open brain that someone is giving me.
Thanks for the help!
