Hello all. I have a DOS and DDR combo I use to dose alkalinity and calcium. I have had to have the DDR serviced twice because the salt creep travels into the PCB chamber, so was curious if people have come up with ways to prevent this? If not, what dosing containers are people using? I would prefer something that allows for some optical sensors (easily). In that regard, can acrylic be drilled if I wanted/needed to drill the optical sensor through the side instead of dropping the cable down? Thanks!
