They used to say that limiting one nutrient, like phosphate, could keep algae in check vs plants.
thanks for enlightening me!
Well I tried that and got the worst algae invasion ever! The more I think of this the less i find it makes sense. Algae's needs are so less than plants, how can you limit nutrients without limiting plants? plants will be affected well before algae no?
So limiting nutrients can only hurt plants not algae in my personal, newbie, opinion.
I keep 1ppm phosphates now in my tank, plants are fine, no algae invasion.
