rossco Posted November 18, 2007 Report Share Posted November 18, 2007 I was browsing a local supplier's shelves and noticed that a german activated carbon product said 'not for marine' use. Why would this be??? :-? How do we know if the generic brands aren't similar?? Just wanted to know if there were differences we should be aware of.

reef Posted November 18, 2007 Report Share Posted November 18, 2007 Could be Likely that it could have high Phosphates or too many impurities. Some brands put cheap, gray clinoptilolite-based rock or Zeolite that is not in the carbon family at all in with their carbon. It is quickly clogged by toxins and trace elements. This loses up to 50% of its effectiveness in saltwater Carbon can be made up of peat and lignite. This carbon has few pores and is slow to absorb organics and will be more lilely to release impurities. Ph drop can also happen with cheap carbons.

slappers Posted November 18, 2007 Report Share Posted November 18, 2007 activated carbon what is the purpose of running this, what does it do Quote Link to comment Share on other sites More sharing options...
reef Posted November 18, 2007 Report Share Posted November 18, 2007 Carbon removes organics and that yellow appearance you can get in the water. The protein skimme cant remove it. I personally dont use it as i use Ozone sometimes and Dose Biodigest which cleans the water. At times i use Zeolite which removes organics, Quote Link to comment Share on other sites More sharing options...

rossco Posted November 18, 2007 Author Report Share Posted November 18, 2007 The product I was referring to is "EHFI Karbon" put out by Eheim. "Binds harmful substances such as heavy metals, detergents, medications; ideal for initial aquarium set-up Heavy metal-free, ph neutral For fresh water only" I assumed it would be safer to use than the 'non-branded' products!
