Activated Carbon Question

[Shep]

Hey,


So I was wondering if activated carbon will also remove trace elements and other helpful chemicals from the water. Appreciate any advice!


Thanks
Tom

I believe it can remove trace elements, but water changes will replenish them.

Heavy use has also been linked to HLLE disease often affecting surgeon fish.

If it was in the filter, would it remove them as I added them in?

Yes.

Carbon technically can remove trace elements, but most of these elements are not in the soluble form in seawater. Carbon will have little or no effect on any of the trace elements in our aquariums.

Here's a couple quotes from Randy Holmes-Farley, who I would have no problem trusting. He runs it so I run it.
Sometimes I'll take it off line for just a little while but always put it back.

I run it 24/7 in a cannister filter.

It reduces yellowing.
It exports organics and metals attached to them.
It may bind organic toxins from the water.
It makes a great place for bacteria to grow for my organic carbon dosing.

Drawbacks may possibly include possibility of HLLE beign encouraged in some fish.

Some folks consider copper and other trace metals (which bind to organic matter which in turn binds to GAC) to be an undesirable impurity that accumulates and is best exported. Others consider it a useful additive that organisms need.

Many of us have no idea whether the amount in the water is too much, too little, or just right. I fall into the latter category with respect to copper, even knowing the measured levels in my tank water.
