Received everything just as ordered. Simple and make it easy to zero in and maintain correct chlorine dosage and carbon filtration for stinky well water treatment. Up to now it has been hit and miss, mostly miss.

Couldn't ask for better service. Fast shipping and competent people. When I had questions, they had answers! Thank you!

GOOD SUPPLIER AND PRODUCTS
