SPS dying

[Screwgunner]

Your corals can not use calcium or alkalinity with out magnesium!!!!!!!

AEF ?

Sincerely Lasse

no, i have AEFW before, i know what they do. this is not it, too fast and all sps all at once.

Have you considered lose dose antibiotic treatment, @AquaBiomics’s protocol?

no, is there a reason to do that? if so please explain.

The only thing jumping out at me is possibly the RODI. 1 of the times I had acros dying I had Chloramines blasting through my carbon blocks. I got one of the $80 Hach kits and figured out I had to change out carbon block #1 every 2 months or chloramine got though. This was when my tank was a 40 breeder and I was changing 5g a week! You are free to borrow the Hach kit btw.

What carbon blocks are you using and how often are they changed?

i use the universal block from BRS, that should take care of any chloramines, yes, if possible i would love to borrow that to see if that is the cause. i only change carbon once every 6 months.

A dead rock restart in September is the most likely, most significant factor. Very difficult to develop a stable microbiome in <6 months. Sure, there could be some other secondary issue, but you have already covered a lot of the bases according to this thread.

Your system is still a microorganism battlefield, with constantly shifting battlefronts and new contestants. Unlike with base and trace elements, it is hard to really measure microbiome "maturity", with the possible exception of AquaBiomics testing.

i think you need to read carefully.
Mg is 1350
Mn is at zero.
please.

If your corals are slowing losing tissue, and it’s not a water quality issue (or even if it is) a pathogen could easily be the culprit (bacterial or viral). Low dose antibiotic treatments have cured several ‘mysterious illnesses’ IME.

i buy that, then there is nothing i can do at this point. there isnt any set rule out there for every aquarium. the aquabimics testing what will that do?

Where is your ALK? I do not find that number.

Also, do you know your PAR values? Let's start there...

I have run tanks at high at12 DKH and then low around 7.5. I know what has worked and failed for me in the past. So I will reply based on what you tell us.

i want to keep that as last option. i dont like blindly throwing stuff into the tank hope it cure thing.

alk is about 8, it's in my OP.
par is about 300 at the top of the rock 10" under water. right now it's sitting around 210 due to acclimation mode with add new led fixtures to give me better coverage. use apogee 510 to do the measuring.

Perfect! No issues with those at all. So here is my final question...what do you feed your fish? Dry or frozen?

 

[Mellotang]

I’d suspect RO
When was last membrane change?

always frozen, its mixed of Hikari mysis, spirulina brine shrimp and selcon. the recent batch with calanus, that's after the issue started.

coral, i do AB+ 3x a week and reef roid on the weekend.

Is it live rock or man made rock? I'm running out of ideas...

ATI test my RO. everything is green.

 

[clownnut]

Pukani, my go to, before that was Marshall island when they were still available.
trust me i am about to pull my hair out. this isnt my first tank, but it's the first time i encountered a problem i have no idea where to start to fix it.

 

[tgrick]

Are you using Tropic Marin salt by any chance? BRS had a recall on it...

always redsea black bucket, i saw that, the turkey batch.

 

[tgrick]

Also, how are you keeping NO3 at that level?

 

[clownnut]

Also, how are you keeping NO3 at that level?

by feeding a lot, NO3 always bottom out for me. i have a cheato run 24/7 with good flow and Pukani, i having a tough time to keep it up. before the reset i dose KNO3 try to keep it up, but i havent dose any since the reset.

Still carbon dosing?
