That is not weird cuz I love it too. Sometimes I look down on my tank and just inhale. They should make a reefer cologne and perfume!!! Oh yeah and to the question as to why saltwater over fresh. Corals baby!! Corals all the way!! Plus I love spending hard earned money and things that will melt for no reason lolI love the way a healthy salt tank smells. Is that weird? That might be weird.
