C**!
I don’t know if you’re over filling these or using the wrong type of chlorine. It smells like super strong, shock or swimming pool chlorine, and my chlorine levels are off the chart with it only halfway open. With the frog ones halfway open keeps mine perfect. I’m going to drop it down to just two slits open and will update if it helps it but man, these things are full. The hot tub is super clear, but the fumes are just unbearable right now.
