Just wondering if there is anything out there that would allow me to monitor alk electronically similar to a PH probe. I'm not looking to control anything I just think it would be awesome to be able to walk past the tank and take a quick peak at the alk level without having to test. I'm just starting to dabble in SPS so I'm paying closer attention to parameters. I have a Hanna checker and do check I'm just wondering if there is any other way besides testing. I'm not interested in an expensive controller as I don't have the need for one.
