Cliff the most impactful thing to me on this page was your top quote where it said that the algae when introduced to non native areas could easily overtake them. That struck me in that the writer didn't say "due to excessive phosphate levels" it took over, it took over because it was introduced.
Thats exactly why I don't believe in water stripping as a cure for any of these invaders. we have hitch hiking problems, not tank problems, but 100% of the time the keeper is told to further strip their water of nutrients
too many threads I have on fastlink where the keeper is using gfo, can't find phosphate on the test kits we use, yet they still have cyano/diatoms/algae genus X etc
of couse we need good quality water for corals, but since many tanks had low levels of dissolved waste as their problem started, it always seemed futile to try and strip the water further to prevent/treat the algae. just musing about that...
I think people will soon find out the new trend in algae prevention is refusing to have it in the tank, taking action the first time its detected the size of a pencil eraser. repeat as often as needed, simply don't let it overtake the tank and lose all your $$
waiting for full infestation while the clean up crew crawls over the target not eating it will be a thing of the past hopefully.
using fire and peroxide has been the king's cheat for keeping my systems clean year after year, hate to see others lose good tanks due to taking a back seat to algae control.
