In short no, nitrates and phospates will feed algae once it has grown but arent normally the cause of it. Also algae only require traces of nutrients to survive compared to plants so removing phosphate or nitrate wont really do much to the algae but if you have plants they will starve.jack dempsey chan;4236841; said:ya but do i have the algae because of high phosphate levels?
