I was just talking about this with my wife last week... who just nodded and smiled and either didn’t get it or didn’t care. So thank you for bringing this up!!!
I’m entering my 4th decade of fish keeping and my third year of my first saltwater tank. With every one of my past FW plants, I usually found myself starting to get bored about 2-3 years in. They always became “set it and forget it” with no additional challenges. Planted tanks helped extend that honeymoon period by about 6 months.
Reefing has been a game changer. While there are still times that my obsession wanes, I find myself wanting more and more every month that goes by. What started as a FOWLR tank 3 years ago quickly became a fish + softies tank, which soon lead to the addition of some LPS... and this past year, ultimately becoming an SPS dominant tank. Not to mention I’ve been collecting equipment for a 30 gallon shallow reef and already daydreaming about my 200g+ tank that I hope you have in a few years when we move to our forever home.
