I have had my GHL system setup since ~December 2019 testing alk twice a day since day one and below is how my Water Sample and Waste Water rollers look. I had both set to max speed per setup instructions. How can I prevent what has happened below again in 6 months, I remember reading some people had their water sample and waste water speed turned down? For what its worth the dosing head for regent and the 4th head I'm using to dose alk look like they did on day one.
Also worth noting that the doser tubes for both the rollers look pretty bad and almost friction burned.
