Just watched that video as well today. Keep in mind, this is her 5th or 6th tank and currently in this video is a 7 ft wide tank. All the other previous tanks she's had, has been an upgrade to go bigger and all tank transfers. So with that said, her rock and water has been somehwat established. She also mentions from her previous 6ft tank it was up and running for about 3 yrs but doesnt mention how long her other previous 3ft, 4ft, 5ft tanks was up for.
And in todays reefing world, its evolved to automation where the hobbyist tend to shoot for doing less physically to enjoy more time watching a home reef grow. To each his / her own, me Im in the middle with the little old and new school. Whats crazy, it that she knows every coral history and where or who she got it from.
