You could do that, or you could just let it stay empty and open the flow up all the way...

The inline chlorinators do have their uses, but the key is to know HOW to use it without getting yourself into trouble. They are great for adding a low amount of chlorine, consistently, or for use during vacations to ensure that chlorine is being added to the pool. When my CYA gets a little low, especially if the temp is hot like it is now (air temp 106 so far, and it's only 1:00--yesterday we got to 110), I'll turn mine on and set it at 2 (on 1-5 scale) so that it's constantly feeding a little chlorine into the water to supplement the bleach additions. And when people go on vacation, they can be a good way to prevent coming back to green water. It's just that they're not to be depended on for sole chlorination method. So...if you don't have a flow restriction problem with it, I'd just leave it connected and empty, turning the flow rate up, in case you need it again in future seasons.
