wrote this thread below based on algae work Ive seen not because I'd like to be the enemy of the establishment ~
I see weaknesses in today's algae care regimen. The prime weakness is not having five threads at sixty pages to show for a given method

Your writing so far reflects upon the exact subject matter intended for this thread above. Most people know to affect po4 favorably and they'll prob be okay from persistent algae. When one person runs a cure on their tank, it only follows that it should work for others, most advice follows this course.
But thats the divergence. Your question and tank details indicates the existence of another form of algae adaptivity in the captive aquarium, one ignored, independent of phosphate, one we are safe from encountering by giving info on algae control where no predictions are on the line.
O2many called it as the ocean does, grazing is what keeps things in check not po4 obsession.
That kind of thick bodied calcareous algae in your tank Budman can resource nutrients from zero phosphate waters. It can and does exist in oligotrophic clean waters in nature and is controlled by grazing from fish and others and not by nutrient levels in the surrounding water, hence the entire point of my linked thread. Painful read, as usual powerful algae battle proof is within as well. Little gems here and there.
People employ a range of actions to get that algae stopped, tangs def can work and are what nature uses. Many go on a months long chase of starvation to try and kill it, gfo galore, clearly that has a following as stated in my linked thread by the number of people disagreeing with my every word
And some people make giant threads simply spot killing it with peroxide until that specific DNA is excluded from your tank and can't come back even if you raise the po4 to .12, consider all options.
