These https://www.amazon.com/dp/B0CPP3FPKS. I compared the chlorine readings on them to my taylor kit and they are pretty close to accurate (show a bit lower values than the taylor kit). But my chlorine has been very stable and the pool is crystal clear based on my cya levels so I trust that what they show on cya side is pretty close.
