This might have been discussed before but... In contemplating a switch from an all LED lit tank, to a hybrid LED/T5 or even back to my MH setup I'm wondering if fixtures that implement T5 or MH end up being more forgiving as far as coral health/growth go. It seems like LEDs allow for a narrower window of success. T5 and MH maybe allow for more flexibility in other parameters like alk/cal/mag levels as well as nutrient levels. Would anyone with experience be able to speak to the theory either in favor or denial? For example, as noted in my build thread I've got some issues with my current tank flourishing. My main tank is lit by LED only. My plumbed in frag tank has LED/T5 hybrid. SPS don't like my main tank so far, but I have a 1/2" nub of Oregon Tort in my frag tank for a little over a month now that has maintained a nice rich blue color and maintains PE. Two things I don't get out of my display. A month isn't that long in the grand scheme, but it has not altered or declined one bit in that month, which is not something I can say about the display. Parameters water wise would be the same, as it's all one system, the only other variable really is flow. I'd like to see some sps folks chime in on this, but anyone's experience is welcome as my coral are mostly soft and lps at this point.
