Warning- bad carbon will kill

[blueyota]

I also have a small diatom breakout in my sand since using it so maybe it is linked together??

I had bought some quitencence carbon from wai;s a few years back.
It was the wai;s branded brand.
But i had huge diatom problems, 2 days after i removed the carbon it cleared up.
I have been told a few times, that the carbon absorbed all that it could and was starting to leech it back into the tank.
If u remove your carbon for 2 days then id say its your carbon too.

Is this the same stuff that Ocean City had at their front door in small containers? They tried to sell me that, but I didn't!!!

If so, Whew!!!

Greg, sorry to hear about the problems. I hope everything recovers and to everyone else, take care.

Yup that is the stuff. I was really happy with how it was working but the diatoms concern me now that there might be a connection.

I am very confused after reading this link.

It appears they add iron into some charcoal as a benefit. If it isn't the carbon that is the problem I'll need to go back to the drawing board.

Anyway you can have the actual metal tested in the carbon? If you can verify its Iron then I would say its back to the drawing board but if its something else that could be your culprit. (That being said I do see what seems to be rust marks on the photos you provided which would lead me to think it is iron rusting...). Excess iron in the fish tank could attribute to some algae problems (Which would explain everyone with dinoflaggelets and slime) but should not be toxic at those levels (When I tore down my 54g I found 5 completely rusted razor blades in the sand ). Greg are you finding that everything in the tank is angry at you or just the coral? What ever the solution I hope you are able to find it fast!

So I found this at Physicsworld.com."It is also difficult to separate these small moments from the underlying "diamagnetism" of carbon. This is a very weak form of magnetism exhibited by almost all forms of carbon (and, indeed, by many other elements) in the presence of an external magnetic field. The external field alters the orbital motion of electrons and induces a small magnetic moment in a direction opposite to that of the field itself." AND the reason for what is most likely iron in carbon."The main cause for suspicion was that many of the reports claimed to have detected only small magnetic moments, which can simply be due to traces of natural magnetic contaminants. Iron, for example, is the fifth most common element in the Earth's crust, and its black oxide magnetite is everywhere in the air.

Funny you mention this. I have had my carbon shut off for two days while treating for red slime. The diatoms are now gone. Crap this really sucks.
