Maybe I didn't describe that well. Someone flushes the toilet, and the water in the tank drops. The water sensor opens. When the tanks fills up again, the sensor closes (detects the water) and then fires another relay one time to inject the solution, not into the tank, but the bowl itself.
The next flush, the water drops, sensor opens.....
I'm assuming here that the sensor is in a closed state if it is in water. I suppose a floating bob switch might work too.
EDIT: Do you think these might work? I'm not sure how the trigger.

Thanks. FigJam did all the work. I kinda tidied things up.
Amazon has a bunch of styles. Look for aquarium or transfer tank float switch. I used these but they tend to fail quickly or are DOA. Here is the straight version. You will need to fashion a mount or stand for them.
Others can post what they used.
You want something like this.

I use it to make sure the reservoir for my plant watering device is full.
