Does anyone have any health concerns over auto-dosing Flourish Excel? Moreso I'm talking about the container of liquid. When I do it manually by hand, obviously it's easy to resecure the cap to limit vapor escape. With my dosing canisters - the lids are literally just "lay on top" style (the Apex DOS kit). I've noticed when I put 500ml in the reservoir it has a pretty severe chemical smell, even with the lid and inside my cabinet. Should I be freaking out over this, or am I just being insane?
