Frequently Asked Questions
Fit & Compatibility
How do I know if Invisi-Lid will fit my tank? Measure your aquarium's outside length and width, then add them together. If the combined measurement is 64 inches or less, Invisi-Lid is a fit. Always use outside dimensions, not inside or "advertised" tank size.
Will it fit my rimmed tank? Invisi-Lid is designed primarily for rimless and AIO (all-in-one) aquariums. It can work on some rimmed tanks depending on rim profile and width — measure carefully and reach out if you're unsure about your specific model.
My tank isn't on the compatibility list. Does that mean it won't fit? Not at all. The list shows popular examples, not every compatible tank. Any aquarium with a combined L + W of 64" or less should fit. The modular design adapts to a wide range of footprints.
Does it work on both freshwater and saltwater tanks? Yes. Invisi-Lid is built for both freshwater and saltwater applications.
Can I use it on a cube tank? Yes — square and cube footprints work the same way. Just confirm L + W ≤ 64".
Assembly & Build
How long does assembly take? Most builds take just a few minutes. Pieces snap together by hand — no tools, no cutting, no glue.
Do I need any tools or hardware? No. Everything required to build your lid comes in the tube. Assembly is fully tool-free.
Is it hard to put together? No. The snap-fit system is designed to be intuitive. If you can build with interlocking blocks, you can build an Invisi-Lid.
Can I take it apart and rebuild it for a different tank? Yes. Invisi-Lid is reusable and reconfigurable. If you upgrade tanks or change your setup, disassemble the lid and rebuild it to the new footprint.
Do I need to cut anything to size? No cutting required for the frame. Depending on your exact tank dimensions, the mesh insert may need light trimming to match your build — standard household scissors handle this easily.
Function & Performance
Will it keep my fish from jumping out? Yes. Invisi-Lid is designed to provide secure coverage and help prevent jumpers from escaping when properly assembled to your tank's footprint.
Does it block light from my reef or planted tank? The clear frame and mesh insert are designed to maximize light transmission so your lighting performs as intended.
Will it interfere with my AIO tank's overflow or back chamber? The modular design lets you build around back chambers and overflow boxes. Because you control the configuration, you can leave gaps where needed for plumbing and equipment access.
Can I feed and access my tank with the lid on? Yes. The modular sections allow for flexible configurations, and individual sections can be lifted or repositioned for feeding and maintenance.
Does it reduce evaporation? A mesh-style lid like Invisi-Lid reduces evaporation modestly compared to an open-top setup, while still allowing the gas exchange your livestock needs. It's not a full glass canopy, by design.
Materials & Durability
What is Invisi-Lid made of? A clear polycarbonate frame system with a fine mesh insert, engineered for aquarium environments.
Is it safe for saltwater? Yes. Invisi-Lid is built for both saltwater and freshwater use.
How do I clean it? Disassemble the sections you want to clean, rinse with warm fresh water, and let air dry. Avoid harsh chemicals or abrasive scrubbers.
Will it yellow or warp over time? The materials are selected for long-term clarity and stability in aquarium conditions when used as directed.
