@melev gives me a hard time for doing this kind of tear down. I've been doing it every two to three years since I started in 2005 and it keeps me excited about corals. I've definitely gotten better at growing them over the years and its all from forums like this, and friends in the hobby to bounce ideas off of. It's a passion of mine that few others I know have.Wow...so much change! You grow those so well, I hope to have such healthy corals some day!
