Simple, effective way of creating divisions in your aquarium substrate layer. Separate gravel, sand, aquatic soil and other substrates with ease! Durable, high quality and made to outlast your tank!

Easily add planted sections and scape out paths and fenced/walled areas to create interest in your aquarium. Non-obtrusive design, features a lip allowing you to bed the substrate divider in place, ensuring it is secure and fixed in position.

Will not float or rise - however, please be mindful if vacuuming your substrate not to disturb the divider too much as you may accidentally mix substrates if you nudge the divider out of place.

Dimensions - 225mm (end to end) x 20mm (height of divider) - the substrate divider also has a 10mm lip previously mentioned allowing you to safely bed the divider into your substrate and anchor it in place more securely to minimise any movement.
