Need SPS help. ICP results included

[jmp21677]

Here's something I just realized and not sure if this could be all or part of the problem? The waterbox aquariums have really small stand and sump areas. They have three hinges on the doors with two above the top of the sump. The hinges are really rusted. Any chance it's part of the issue?

If it’s flaking off into the sump, yes.

From the one pic that was posted, it doesn’t seem like alk swings.
A nutritional deficiency is, ime, a slow STN type of death. But he said he doses Reef Energy AB. But it’s possible.

Did I miss mention of parameters? Tank age?

ALK
NO3
PO4

Is there any algae in the tank?

I don't have personal experience with tin, but a bit of aluminum doesn't affect SPS IME.

 

[Whasmack]

It was in the ICP test - 8dKh, 0.05 p04, 11 n03 i think.

Aluminum at those levels doesnt affect sps.

Right. Sorry couldn't see those on phone but desktop I can. Those numbers are fine.

Doing water changes every other week. Sps death varies. I bought a small pack two weeks ago thinking I had figured out my problem. Green birdnest dies in 4 days. Phoenix monti is fading in color. Wwc yellow tip is doing well so far. Par is 400 middle top of tank. I am running AB+ on the radion at 45%

How old is the tank? Sps doesnt seem to do well in new tanks with dry rock.

The rock and some livestocl is from a previous system. I started this system about 18 months ago and it was an upgrade.

I tested for stray voltage and got small reading of .06in my sump. Tank moved from 0 - .15

i dont think that this is the problem.

In my tank have 10-15 volts (i do not have a good grounding and my fishes, LPS & SPS are fine, also i read about the use of current to stimulate the coral grow)

I read that you have your Radion in 45%? i think is very low you could rise to 70% but in a slowly way.

also do 5 water changes of 20 % weekly and after that 1 or 2 of 10% per month

as i told you, i had the same problem and this were the solutions that i did.

i had low light with a blue spectrum all the day and the excess of tin in my tank, i changed this 2 things and the corals started to grow .
