Automatic Top Off's are essential to keep the salinity in your reef stable! With so many pricey ones on the market, i figured why not DIY my own for super cheap! (and it works well!!!)

Check out the youtube video for build instructions. Parts list is in the video description.

Be sure to double check the measurements of your pump and the housing before printing.
as always build at your own risk! and have fun!
