Same here.I have never , nor have I considered doing such. There are ways and alternative ways to combats algae, Dino, chrysophytes and other issues and to take all the hard work and patience to get a tank established and seeded to turn around and tear it down or rip clean is plain and simply senseless
I Do realize there are circumstances that warrant such action, but again there are alternatives that often require trial and patience.
Except for a leak in the 135 DT 6 years ago. Worse yet, it was 4 days before a 2-week trip overseas. Fortunately, I had an empty 55 and two 40-gallon basement sumps. I cut up colonies and moved them, live rock and other livestock to basement 55 and sumps. Most everything survived but many of the Acros were not happy.
