So I have owned my reef bot for about two months now and honestly it's way easier to operate and manage than my GHL KH Director which I have yet to get working successfully since I purchased it. However, I am experiencing an issue were my test are coming back unable to read parameters and I have done everything I can to try and troubleshoot myself. That includes replacing the reagents completely with reagents from brand new test kits, cleaning the vials and yet no success. I am not a fan of the technical support as I feel there is a lack of responsiveness from the group. So here I sit with no ability to test as I wait. :-(
