Food for though for all of us using carbon...

...Earlier this year, Jay Hemdal (et al.) conducted a ground-breaking study that was the first to scientifically establish a link between the use of granular activated carbon and Head and Lateral Line Erosion Syndrome (HLLES). The study is published in the North American Journal of Aquaculture...

Wow, and how many of us would go with out carbon our tanks?

 

[coolname1]

I never ran carbon in my tank and I'm sure alot of people don't either..

 

[alexrex20]

No carbon here...

 

[flexrac]

no carbon here, filtor socks work great, when i use them, that and UV.

I use ROX 0.8.

I posted about this a while back

rxonco you seem to have stirred up more feedback than I was able to get.

I was curious if SeaChem Purigen would be a good alternative? Anyone ever use it?

I am still under the impression that its the dust. I have been using carbon for 10 yrs, I always thoroughly rinse it and have never ever ever ever had HLLE.

Well this is interesting. Our Petco sumps use two large bags of activated carbon in all of our saltwater biowheel systems. Ours are pretty thoroughly rinsed before use to get all the powder out but they make such little note about it in the Procedure manual.

That's what the article speculates. The dust is what causes it.

This is good to know. Just purchased 2 TLF reactors for gfo and carbon. I'll have to make sure to rinse the carbon really well and try to se up a filter for the output to be cautious.

What do you think can trap carbon dust?

 

[rxonco]

If the dust particulate from the carbon poses a problem, I'd be inclined to say that the dust from GFO could do the same.

 

[NarnyTheGreat]

I wonder if the "dust" continues to pull away from the carbon or if its just from not rinsing it well enough. They dont say how the study was performed so we dont know if they rinsed it really well or if they just put it in the filter.

Does anyone know how they conducted the experiments?

Is anyone going to stop using carbon because of these findings? I also use Rox 0.8 and it's going to be pretty hard to give it up. It's amazing how clear my water is after I clean my reactor and put fresh carbon in.

I'm going to try purigen from SeaChem at some point. Was planning to anyway since it supposedly be can regenerated.

 

[rxonco]

I've used Purigen in the past with good results. I don't think it "polishes" the water as much, but as a "carbon-like" sponge, it's fantastic. That may be the first time I've ever typed the word fantastic. Not in my normal verbage.

How common is the disease? Not that common in my opinion to make me stop using carbon; never had any issues for the last 15 years.

LINK:"It is still unclear why HLLE does not develop in some aquarists' systems with GAC usage."

I think more research needs to be done based on the statement above.

Kind of like fabulous. I don't know why but that one drives me nuts and whenever I type it I want to type fabuloso!
