Your chlorine cannot "be inline" if you are fighting algae. (I'm not sure what level that means.) The way to kill algae is to shock your pool (based on your CYA level) and hold it at that high level until it is dead. Brush the pool frequently when the chlorine is high and run your pump 24/7, cleaning your filter as needed. Take a look at the Best Guess Chlorine Chart in my signature below. It shows the correlation between CYA levels and needed chlorine levels.
