I would think that that was way too drastic. I tried the bleach approach.
It kills the algae but it comes back. I don't think that tearing down the
whole tank, treating it, and recycling is a very good answer. Kind of like
treating poison ivy with nuclear weapons. I got some SAEs (ordered the guy
in California, I forget the name). I paid a premium price but it was better
than a teardown. It took them a few weeks to do their work but they were
very through. They seemed to do a specific plant at a time. For the first
week all they ate was flake food. Then they started grazing in a school.
They were pretty neat to watch. If you can find a source they are the
answer. There was a wholesaler in Florida mentioned a while back. If
no one will ship to you in Canada, perhaps a local dealer could order from
them. Good luck, Pete
