takes forever to fill your top off tunze is better louder alarm and much faster when it comes to filling your top off but again it’s just my opinion others might think otherwise I have there controller and dosing pumps luv them just not the ato
Knock on wood mine has been working flawlessly. I also opted to Hook the water refill up to a John Guest t fitting along with my alk dosing line. This way it flushes the alk line with RODI every time it comes on.
