I always have such algae when too low doses of PO4 and NO3 are added or when NO3 is close to 0 ppm and PO4 is present at 0.5..1 ppm.
But in your case it seems it may be cause for too high iron level for example. How much micros do you add ? (you said you have rich substrate which can leak some nutrients into the water column)
The picture you saw was taken when i added too much NO3 and micros.
