SPS issues... again.

[Palmer]

What intensity (%) do you have the LED's at? I am not familiar personally with them but my understanding is people dial them back initially and some have burned up their coral when having them on full intensity.

No techy here but I would think the LED's are giving off too much light as Palmer suggests or insufficient light (for SPS) which was problematic for the early LEDs.

I was going to suggest you post the name and model of your LEDs and one of our lighting gurus can help you out.

T5 to LED could potentially have been a huge jump in lighting intensity. I assume your frag tank has had consistent lighting? That's a pretty obvious tell that it isn't a chemistry issue if the system is connected.

Agreed..

They are AI Sol Blues. I started them at 30 or 35% and have been slowly ramping them up at a rate of about 5%/2-3 days. They are now at 90%. Yes, the frag tank lights have remained the same... they are cheapo LEDs... not even sure the brand name. I am running RO/DI... TDS out is kind of strange... on the Vertex built in TDS it ranges from about 1-15... on my external TDS meter, it reads around 0... not sure which one to trust, but i lean towards the external one as the RO/DI unit is brand new. My phospates are below 0.05... a little higher than I would like, but not too bad. They are dying via STN, and some have damaged/burnt tips.

I've been trying to pay extra attention to what the fish are doing lately, and I'm going to say the the flag fin may be nipping after the lights go out and the moonlights are on... it's been tough to catch him, but I'm starting to lean towards him as the culprit. Maybe. I think I may have to break out the fish trap and get rid of him... and my Lyretail jerk face Anthias while I'm in there. That said, any ideas...?? Keep 'em coming!

That just leaves your lights, predators, stray voltage or SPS voodoo. You haven't said how they die.

When you say that your sols are at 90%..... is that the whites and the blues? cuz the ones on the display at work are like 18 inches off the tank and I still have the whites at 70% and the blues at 100% and everything is doing great! crazy growth and color.... well as you have seen....

I've got the whites at 90%, and each of the blues at 85%. The bottom of the fixtures are 15" above the water. I started to notice these issues while the lights were at low intensity... I've been hoping that there wasn't enough light and once they ramped up these problems would go away. No such luck. I should also mention that I got the angel at around the same time as the lights... so that doesn't really help for troubleshooting.

I had mentioned earlier... they are dying via STN and some have burnt /damaged tips. It's really frustrating to have the frags doing/looking so good, and the important stuff (display) looking like crap. I've even taken a few pieces out of the display and put them into the frag tank and they look like they are healing already.

if its coral specific say all your sps and not your lps then i would lean towards the angel as well if its not chem.

Yes, it is only the SPS. All of my zoas (except for a melted CAR frag... damnit) are looking really good. LPS... really good. Clams... better than ever. As for the chemistry, I'll have to run the test gauntlet soon, but like I had mentioned, the frag tank looks great which eliminates this as a possibility in my head. Last time I checked, all parameters were right around where I want them... Ca ~400, dKh ~7 Mg ~1250-1300 (I know, a little low) PO4 0.01-0.05, no measurable nitrates, nitrites or amonia. I'm running GFO, and Carbon 24/7... and full Zeo.
