DIY Automatic Top Offs are a must-have for maintaining stable salinity levels in your reef tank. With expensive commercial options available, I decided to take matters into my own hands and build one for pennies on the dollar - and it works like a charm! To replicate this project, head over to the YouTube video linked below for step-by-step instructions. In the video description, you'll find a detailed list of required parts. Before you start printing, make sure to double-check your pump's dimensions and the housing's measurements to ensure a perfect fit. As with any build project, please proceed at your own risk. However, I promise it will be worth the effort - just have fun and enjoy the process! Visit ReefDudes.com for more DIY projects and tutorials.
