Im on all the fun lists! 😄but it is a potential explosive so may be covered by legislation in some Countries.
Ah I didnt know they were stricter in Germany than in Norway with this We have two lists of chemicals, the first one is the no-no-no list and the second one is "We'll be watching you closely" list. Is there not a system like that in Germany? For me KNO3 was on the second list so I took the chance and havent gotten any scary phonecalls yet. I figure if they do call on me I will invite them round to view my tank and discuss why ammonia dosing isnt straight forward in aquariums with fish.Getting KNO3 is completely out of question in Germany.
