I dont believe that if you are a reefer that put your heart in making your animals grow and thrive, that you could leave the hobby behind just like that. And it's not really true about those new 400$ leds.. If you use them properly they will make the change, but you need to give it time. In reefing that means months and years, because anything that goes fast in a reef is negative, and you can kill or make permanent damage in mere hours. Slow changes are mostly good, but need patience and passion. If you lost the passion you had, its propably due to something other in your life.
I did quit reefing because of divorce that broke my bones and pulverized my mind...
it took me 15 years to make the desicion to start a new tank. It was like starting at scratch with all the development and modernizing of everything, and the knowledge and understanding have grown so much during this year. At the same time that made things easier. Just look at the apps we control everything with now..
I hope your reason to brake down your tank will solve itself and you heal like I did, and that you come back. I really do, I want you to actually feel joy over keeping those beautiful creatures, and that it becomes a way for you to heal next time you start up.
