Interesting. I typically clean the culverts in tap water and then dry them with a twisted up paper towel. I wonder if enough residue is left in the culvers to cause a problem. Would be awesome if that's the case because its the only Hanna product I have ever been disappointed in.
That's the exact same thing I was doing
