Interesting... I find my flavor tastes different in some of my tanks that I have. It's kind of strange, but???I put the same flavor liquid in the horus as what I've been running in one of my zeus tanks and I don't know if it's better but it's definitely a little different. It's a butterscotch tobacco flavor and in the zeus the butterscotch comes through stronger where in the horus it's more of an even mix between the tobacco and butterscotch.
