Idea:
What is the strongest liquid chlorine you can get? (12.5 best I got) if you could find some 30+ you poor in to a 1L bottle pick it 1-10 (or what ever works) times with a needle and then drop it in the chlorinator.
Bam! Matenence free for 3 days. I need to do this. Otw to see what will fit in my chlorinator

Better yet I could rig a detergent feeder from an old pressure washer in to the plumbing.
