i was told uv bulbs were good and they did ok for about 9 months before wearing out.t5's are supposed to last longer.so i got GIESEMANN
bulbs this time and so far i'm happy but its only been 3 months so i'll know in like 6 months if their better,as advertised i wish i could test them cause i think their brighter.i raised my light 2 inches higher off the tank and the corals seemed healthier.i have 2 54watt 11,oook t5's and 2 actinics over a 55 gallon tank and i think its to bright for a few of my corals.they expanded better after i raised the light.
