theres a discution about carbon that can eliminate trace elements from
the water, i guess thats true, what other media i could use in my tank
to maintain water clarity but keeping the trace?
The experiment you refer to is on The Krib. http://www.thekrib.com
You might try Seachem's Purigen. I have some, but am not using it currently. The product label states that it "polishes better than a diatom filter", and "has virtually no impact on trace elements". The front label has something like "Organic control" or something like that.
You must buy Seachem's "The Bag" to go with it, however. The particle size is so small that it requires an inflexible bag. Panty hose, and your garden-variety filter bags will let the stuff through. A plus is that the product is rechargeable, using a bleach solution to clean it.
A similar product is Hypersorb, also by Seachem. I've not tried it, but the product description was similiar.
