I have been in the hobby for over 30 years and finally started to automate my reef tank. Just set up RS Reef Dose. I have been dosing and topping off for years before leaving for work every morning. Next is ATO so early morning reef chores will be eliminated. My 65 is a sump-less rimmed tank and I had to improvise where and how to secure dosing tubes. I drilled some small holes in the center brace and used the end caps supplied with the RS dosing tube kit put a drop of krazy glue to secure and done! Neat and organized. Setup was a breeze as I am running RS led 90’s and I am very familiar with the reef beat app. Next is ATO.
