DIY biOrb water changer hack: Just pour fresh water in the top and dirty water automatically exits the side!

Revived a 13-year-old yard-sale biOrb with a custom side-drain system, rubber gasket seal, layered aquascape, and Anubias glued on rocks. Super easy maintenance for nano tanks, betta bowls, or shrimp setups.
