For me its growth increase my par potential as well as appearance. I will keep leds going which are purty to look at just dont want to get to blue when t5s kick onGood comments, so far, but I will ask the goofy question. What do you want to achieve with the added T5s? I ask because some shoot for maximum growth, some for maximum color, some for tank appearance and some for a combination of two or all three.
