The process is quick and easy. The cap at the bottom of the Eko Klor twists off for you to remove the old anode. You may have to compress the spring while you replace the anode. Once the cap is removed you can unscrew the old anode and screw the new anode in. After the new anode is screwed in and tight, you can replace the cap.
You can order replacement anodes from our website http://solaxx.com/ekoklor_parts.php
