I thought someone had mentioned possible issues with Kent carbon awhile ago, but I was searching the forums and couldn't find it, so I figured I was imagining it. Now I'm going to go look again now I know who it was...

EDIT: Here is canuckgod420's experiences back in November... http://www.canreef.com/vbulletin/showthread.php?t=80526

I guess the important thing is to have proof of purchase if you don't have any carbon left.

I lost 2000$ worth in coral. That's the price I would need to pay to replace what I lost. I too started a few of these pieces with little frags but they were no little frags anylonger so they are not worth 30$ any longer. Even if you bought your corals are 10$ frag, they are worth a lot more when they grow large. It is that cost that you must calculate because replacing those pieces would cost that much.

Try dragging a magnet thru the carbon and see if you get any metals?

wow... reef central thread store owner lost a ton of coral.... I really hope kent steps up to the plate and pays for or replaces everyones losses... everyone affected should write a mass email to them stating their displeasure! The more ppl that send to them what happened the better it is for them to investigate what went wrong...

Very smart Idea!!!

Thats funny Myka, you even posted a response to my thread.

Anyway, its all good now, everything looks great and growing fast.

I'm actually thinking of adding this carbon every few months to shock up the corals a bit and watch them explode in growth and colour again.

Having a bunch of disgruntled reef keepers suing for compensation is a good way to put a company out of business. I'm not sure I agree with that...take a look at what happened to PFO. I'm sure there are more people that miss PFO then there are that are mad.

Store owners should know better than to put $20K of coral in one system - that's a really bad idea. That's called laziness...it is easier to maintain one or two big systems than several smaller ones. You can't purchase much in the way of insurance on live corals or fish, so they have to create their own types of insurance. Multiple systems is the best insurance they can get. I still feel darn awful for the store owner who lost this huge investment, as well as the animals that died though. That is awful.

Yeah, I was really thinking I was losing it. I spent at least 20 minutes hunting for that thread before deciding I had lost my mind. Then jjntm mentioned your name and I found the thread in approximately 8 seconds!

Not possible in my case because i put the carbon in the evening where there was just the actinic T5 on, then when I woke up the light was not even on yet, but I could see something was wrong. EAch morning when I wake up the first thing I do is to check my aquariums.

It must be something else. I do not beleive that 8 hours of Kent carbon could have stripped so much from my water than corals were dying. I used carbon on regular basis since the beginning of that tank, but was using Seachem.

I beleive that something far more serious hapened here with some batch of Kent carbon. It could be some heavy metal, as I don't think that carbon can absorb copper or other toxic metal so it could have leached something like that. I just got my water analysed for heavy metal 3 weeks ago and it was perfect. I will have it check again just to be on the safe side.

When I saw this I immeditaly removed the carbon and did a 30% water change. That was the only thing I had done to the tank so it was the first thing I removed.

A lot of stores have common water in their system. I am not sure if you realize this but he lost 10k of coral worth...and it does not take that much in coral to reach that amount. I personaly have about 3k to 4k in corals worth. I lost about half so far.

I can think of plenty of coral stores here that would have the same exact issue because all their aquariums are connected with the same water. It is very common.

I don't think they do it out of laziness, probably more out of economical issue. It is less expensive to have a big central system I guess.

And your point may not be valid even if he had a few independant systems. Assuming he was doing the regular maintenance shedule of replacing carbon, what is to say that he would not have put new fresh carbon in all of his independant tanks killing everyting anyway?
