Even with the autochlorinator you will still need to put in liquid weekly. Depending on your pool size you should be looking at 2.5 to 5 gal a week. Also I am a HUGE fan of Drop Out. Put a bottle in and run the filter for 2 hours then shut it down and let sit overnight. The next day vacuum on waste and all that crap goes right out the drainage hose. Pool will be crystal clear the next day!
