I have not when I was dosing flourish at 10mls 3 a week with 50% weekly water changes in 20 gal of water.

But I did not dose Flourish iron as well.

Good consistent CO2 takes care of it.

Why have I not had BBA for many years and others have?
Why can I induce BBA by lowering my CO2?
Why do good German planties know this also?
Keep trying to do all the other methods, till you have done them all

Meanwhile I have no trouble with algae, BBA etc....
It's not magic.
