No problem. You could always try 500g or 1ltr first and see how that goes. Then simply increase the amount. If it doesn't work for the Nitrates it will work as regular Bio Media, so won't be completely useless. If/when you try it, please let me know.....IanOops, yes - bit sideways on topic. Thanks for the info. I reckon I could do a few kilos but I think I will swap it into the slower canister. Will have to check flow rates when back home to see how different. Can't do it for a bit, will have to be later in year.
