This fact causes the most problems when people see a lot of stuff (food) that their skimmers have removed, but wonder why their nuisance algae is not being removed (skimmers don't remove Inorganic Nitrate and Inorganic Phosphate), and also when their phosphate tests zero, but they still have algae on certain parts of the rocks (the invisible phosphate is coming out of the rocks.)
I do not think we can say this.
The evidence does not support the conclusion.
The issue is one based on germination of the algae in question, not nutrients in and other themselve, rather what starts the germination of the spores etc.
You stop germination/signals etc, you stop the growth and problem.
Most aquarist have an extremely poor understanding of algae and their life history.
So if noxious algae are indeed due to inorganic forms, such tanks disprove such hypohtesis and falsify them.
The livestock/plants etc does matter there, however, the inorganic nutrients in and of themselves are not the "cause".
You need an alternative hypothesis that addresses these observations as well
Observation corleation and wishful thinking alone is not enough, you need to test and confirm under a few different situtations. You need enough control to grow the tank without any issues prior, then add the dependent variable.
Otherwise you end up promoting a myth. Don't do that, that does not help anyone in the hobby.
Here's a tank with 15ppm NO3, 0.3ppm of PO4 and it's pure inorganic:
