Tagging along
 

I've got two full unopened buckets with these numbers. I think I purchased them at Ocean Aquatics a few months ago. The sticker on the lid says 11332.

As I understand it the sticker on the lid is the batch number. That is what the LFS guy showed me today when I went in and asked. Unfortunately my Son colored mine in blue pen and I can't see it lol.

whoa people...before blaming the salt it must be analysed to see if there is something that can be killing corals.

It could be other things as well. I don't know if you use tap water or if your RODI is a bit old and could be leaching some toxic stuff from the city water? You must absolutely have this salt analysed by a pro lab before you do anything.

I had my tank poisoned by copper and nickel from the kent carbon and the first thing I did was to send a sample to a professional lab and get the result. Kent paid all my dead corals so that's good and I presume that if it is proven that there was something in that salt crashing your tank, then they would give you a compensation. I am surprised that you're the only one having this problem though, and the cloudy water can be a bacteria bloom caused by a fish dying and then ammonia would surely kill your corals and irritate the fish, if not kill them.

Copper does not do this to LPS, in fact, none of my LPS were affected with copper poisoning. I have seen a duncan near death once and it was from too high nitrates.

YOu should first do proper test on your water to see if everything is good, then send a sample of the salt (fresh batch!) to be analysed, then you will know if it is the salt or not.

I have been using Reef crystal for years and never had any bad results, plus it should not be so potent as to crash everything from just a water change, since you're not replacing all the water but just a part.

Just like to add a BIG thank you to Concept Aquatics for the good deal on salt. I will be doing a major water change asap.

Sorry,I made a mistake on the batch number. I just looked at some old buckets and mattjoly85 you are correct. Can we please verify where Instant Ocean places the batch numbers? The only sticker on the bucket is on the lid which reads 12128. Correct me if I am wrong but I assume that is the batch number?
Levi,
Yes,I still have the whole 160 bucket. I only mixed up 6 gallons from it.(my tank is only 25 gal)

I just checked . . . mine doesn't have a sticker on the lid.

Either it fell off before I got it . . . or I'll find it stuck someplace strange within a three-year-old's line of sight (kids!).

Yep kids and stickers... You can make a five year old do anything with a couple of Spiderman stickers.

Jason so so sorry to hear that buddy. I know how much u love your Acans and remember we talked about me buying them and fragging them back to you after u moved. To bad it never worked out man Sorry for your $$$$$$$$ loss it's rough when u hace so much in corals and they die just so fast.

So sorry man I can only imagine... If you talk to instant ocean about this in the future to try and get some compensation; just remember you catch more flies with honey. Don't flip, stay calm tell them what happened and how devastating it is to you and I bet they will help any way they can.

@daniella3D didn't you read this whole thread? There are other cases of this exact same scenario, it IS happening to other people, not just J.

IMO, the problem is that if the batch was bad, there should be thousands of people with the same problem.
The numbers of people with the problem are statistically insignificant when dealing with the size of a batch mix.
It's too easy for someone to blame a batch of salt and then others having problems jump on the band wagon and feel the salt is the cause of their problems also.
Can you find even a hundred people who have a problem that they are blaming this batch of salt on?

Or a small amount of contaminant could have been a part of the batch too; along the line, during shipping, who knows. It's worth investigating at least. It would be a shame to ignore it and have others' tanks wrecked if there is truly an issue.
