SPS issues... again.

[fishytime]

Maybe basic questions but..... Are you using RO, RO/DI, tap?.....do you know what the TDS of the water you are using is?.... Have you tested the water for phosphates? .... Nitrates?..... Any leathers in the tank..... And I know you said you've never seen your angel nipping, but that doesn't mean that it isn't happening.... It seems that fish somehow know when you are watching and put their halos on

Except mine........my angels make direct eye contact, open their mouths wide, chomp down and dare me to do something about it

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....

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.
