The Ultum Nature Systems (UNS) Dual AIO Rimless Aquarium Glass Lids are specialized, high-clarity glass covers custom-engineered to fit the exact display footprint of the UNS Dual All-In-One tank series. Designed to sit flush over the main viewing area without obstructing the rear filtration chambers, these lids provide a sleek, low-profile barrier against evaporation and jumping livestock without disrupting your aquascape.

1. Why doesn't the Dual AIO lid cover the entire top of the aquarium?
The lid is intentionally sized to cover the display area up to the acrylic filtration wall. This leaves the back filtration chambers accessible for routine maintenance while ensuring adequate surface gas exchange and cord pass-through room.
2. Can I use these lids on a standard UNS rimless tank or single-chamber AIO?
No. Standard UNS tanks and single-chamber AIO models have different display footprints and back-wall positions. Please ensure you order from the standard UNS Glass Lids collection if you do not have a Dual AIO system.
3. Will the glass lid interfere with my aquarium lighting?
No. UNS uses high-clarity transparent glass that allows full light spectrum transmission, ensuring your aquatic plants or corals receive the PAR levels needed for healthy growth.

"BucePlant gets a 5-star rating because they delivered just as advertised. It was in-stock. They said 3 days, it was 3 days. The packaging was great. My LFS doesn't carry UNS. I called down to Ocean Floor in the PHX area, and they were out of stock. UNS gets a 3. It looks great but why doesn't it have a little hole, for feeding? A handle to lift it up?"
"Shipping was quick. Well packed - no damage - fits the tank perfectly."
"Fast shipping and great service! The tank is beautiful!"
"Really enjoying this tank."
"Very nice and sleek"
"Fits my 45A AIO perfectly. This will be a big help with evaporation and help keep salinity levels stable. There are gaps in the sides but not big enough for fish to jump out. This is my favorite place to shop. Customer services are always top notch."
"Tank arrived very quickly and well packaged."
"Product came well packaged, undamaged, and faster than expected. The lid fit perfectly on my UNS Dual AIO Rimless Tank (2nd gen) using the 4 provided anchors. Pros: Sleek look with space between the walls and the lid for CO2 accessories and a Twinstar M5 algae inhibitor when the accessories were placed on the same side. Cons: Could not fit the drop checker with the lid on. Pretty difficult to take the lid off gracefully (which is probably a me problem). Overall, it's a functional lid for what I needed it for!"
"Excellent communication by text and it arrived earlier than expected 😊"
"Got sent the wrong item and they haven't responded to my request to replace or fix - it's been over 3 days and no response. Would not recommend based on this experience."
