I'm betting you shocked most things with a lot more light. How high is the fixture off the water? What percentage do you run the LEDs?
I'd ditch both Aquablue bulbs. Add another blue plus and an actinic bulb to round out the spectrum. Do not run the LEDs over 25% for a little bit. I'd run the T5s at 50% to begin with. Maybe for a week? Then start slowly adding 10% every week until you hit 100%. I doubt you'll ever need the LEDs over 50% but measure PAR and see where you're at.
What are your nitrates and phosphates at? If 0, bump them up and get your corals some food.
Also, what size tank is this and how old? Sorry if it's in your signature, I'm on Tapatalk and don't see it.
Hey, no worries. Tank is 6 foot long, 2 ft deep, ten weeks old....was cycling for 6 weeks, and corals transferred over from old tank about 3 to 4 weeks ago.
ati unit is a 4 x 80 watt tube, 4 led panel. I was careful not to blast them with too much initially, I started at 30% leds and t5s, with unit about 12 inches off the water. Par level just under surface was about 200, dropping to 50-100 near the bottom. Very conservative i thought.
I have since increased t5s to 60%, with leds at 40%. I heard the leds where pretty concentrated in their output, so was a bit scared with them. Par not much different at surface tbh, but more like 150 further down now.
I do have some more blue plus bulbs, just waiting for a spare basic fitting plate to arrive so i can burn it in at max for 48 hrs, then swap it in.
As i mentioned, there are lots of other potential causes for unhappy corals too...its a very new tank. So still struggling to get alk stable for example. Nitrates are at 6, phosphate 0.06, so i think they are fine though.
This hybrid thing is witchcraft to me though, after the simplicity of the radions!
What t5 light spectrum do you set the leds to copy, using the ati program? I just picked blue plus, which has no red in it at all. Do you use a preset, or have a custom blend?
What par do you personally aim for at top middle and bottom in your tank?
