is presently being discussed in the Reef Central DIY forum.
It was widely discussed on the Reefs.Org General Reefkeeping Discussion forum as well a few months back until it was closed due to the discussion "straying from the subject matter".
CanReef DIYers might find this new twist very interesting...
