Greg I was there when you bought it. How fast did you see negative results? Have you let the store know what you have found with the carbon?

I called the store but I think there was some impact lost in translation

I just tried the magnet test on unused Korallen or zeo carbon and elite aquatic premium carbon and they both were picked up by the magnet. Not sure why but my question now is, How accurate is this procedure. Can everyone with a strong magnet test their carbon please. So far Black diamond,HBH,Korallen,Elite Aquatic premium. all are magnetic

carbon
 

I tested my Kent marine reef carbon and magnet picked up a few pellets too.

I don't have corals but have been using the stuff for a month with no ill effect on anything. I honestly thought it works fantastic. The only thing I have noticed since using it is diatoms, which prob have nothing to do with the carbon. I never had an issue with them before.

I do see little rust spots in my reactor though, but maybe two or three little tiny pieces.

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.

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.

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.
