Established SPS tank, slowly rotting away.

I always tell people to calibrate their refractometers almost as often as they use them. Some of the cheaper ones can go bad quickly and some of the calibration fluid doesn't last that long either. I personally think some of the best no way I have spent was on my digital refractometer. I hope things recover fully.
 
Well, I'm glad things are recovering. I am going to go home and check my refractometer..

Khian, your tank photos were really quite amazing and you are clearly a talented reefer.
I think I speak for many when I say that it would be a pleasure to see more of your tank and more posts from you around here.

You are welcome anytime!
 
Are we talking about two different tanks here? The original thread was by Kurkis493.

Kurkis493,

Any updates on your tank?

Oh sh*t.. Yes... Kurkis!
I don't know what I did there. I mean this thread by Kurkis..
But there seem to be two people responding khian and Kurkis

I'm a little confused.... And not too bright!
 
Man so sad to see. Please forgive me if I missed(skimming at work) it but have you thought about sending your water to Triton or ATI for testing. I was having massive issues with SPS a little while ago and found out I had high levels of Aluminum and Lithium. Shortly after I did a re-boot and my SPS issues are gone.

Hope you figure it out

On a side note I had the same issue, turned out it was coming from my ceramic media.
 
wow never would've guess salinity to be the culprit,glad to see the issue was resolved before it was too late.Btw the way a photo update would be nice.
 
The op hasn't posted what the issue was yet. The reply saying it was salinity was from another user (confused me too) which I am not sure what they were responding to.
 
I went through his build thread on his local forum.
Looks like he broke down the tank the end of September.
He was moving and wanted to start fresh.
 
Lithium isn't as deadly as some described.
I have purposely dose lithium chloride to 5 x NSW in my tank and I can tell you it doesn't kill corals at all.
It is detrimental to algae of all forms... my snails started to die from starvation.
Which wasn't a good thing to have. All invertebrates and fish was not directly affected by lithium.
 
Have you increase your water circulation over time? As corals get more dense it is harder to get good flow to all the parts. I am fighting something similar. My SPS get random dead spots, but no sign of pest. I suspect a flow or bacterial issue. New RO/DI filters arrived yesterday so going to get cleaner water. I also added a gyre 130 to my two vortec mp10s to try and up the circulation to see if that helps. There is also a fair amount of turf wars going on in my tank and that contributes to some of the random dead spot.

This was my thought. I started to suffer from STN when hair algae clogged my MPs. It stopped after I cleaned them.
 
What was wrong with the media?Was it leaking chemicals into the water?

Nothing was wrong with it, just that all ceramic media leeches Aluminum and Vanadium as it breaks down. I had the marine pure balls and they were getting really brittle, turns out they were slowly dissolving into my water column. Triton test showed sky high aluminum and vanadium, corals looked great once I switched the ceramic stuff out for siporax which is made of inert glass.
