If you love the look of a rimless tank but hate topping off water every two days (or worrying about your prize Betta taking a "leap of faith"), these UNS Rimless Glass Lids are exactly what you need.

Designed specifically to fit the Ultum Nature Systems lineup, these lids offer a clean, low-profile solution to the two biggest headaches in the hobby: evaporation and jumping livestock. They are precision-sized to cover your tank while still leaving just enough room for essential gas exchange and for your filter pipes or heater cords to pass through.

Depending on your aesthetic and the specific tank model you have, you can pick from two different mounting styles:

• Glass Lids with Clips: These come with high-clarity clear clips that sit securely on the edge of your UNS aquarium. They’re great for a classic look and offer solid stability.
• Flush Glass Lids: For the ultimate minimalist, these sit right on the inner rim using anti-slip strips for a secure, "barely there" placement that doesn't disrupt the clean lines of your tank.

Key Features and Benefits

• Provides peace of mind for active swimmers and jumpers like Bettas.
• By cutting down on evaporation, these lids help keep your water parameters and salinity levels much more consistent.
  
• Made with high-quality glass that doesn't block your light, so your plants and corals can keep thriving without interference.
