Walstad deals with tanks from one narrow perspective - the "natural" style. Maybe in the conditions of that particular style of tank, excess iron might cause algae.
But the existence and success of other systems like EI demonstrate that excess iron does not universally lead to algae, at least in other tank styles.
Even assuming it might, your own tank demonstrated for the last two months that there is a happy medium, as you had neither algae nor deficient new growth.
And the system you're using, PPS-Pro, is the very definition of trying to maintain happy mediums, through reading plant and algae symptoms. So follow your system! If the plants need something then dose it. I guarantee unhealthy plants are a bigger algae inducer than a bit of any extra nutrient.
