Each piece measures 22.68 x 16.93 x 0.16 inches including the plastic strip.

Best for: Aqueon and All Glass tanks in the 75/90/110 gallon range. This two-piece design is sized to fit one side of compatible tanks.

The hood uses tempered glass for safety and durability, with a note that fit may vary by brand.

Buying Guide
What should you consider when choosing a hood for a 90-gallon tank?
- Tank compatibility: Verify the exact model and opening size of your tank. Small discrepancies in width or length affect fit. Look for statements like “fits 75/90/110 gallon” and check your tank’s measurements.
- Material choice: Tempered glass is durable and scratch-resistant, but heavier. Polycarbonate is lighter and less fragile, though it can scratch more easily and may require careful cleaning.
- Two-piece vs. single-piece: Two-piece canopies may offer better airflow and easier access, while single-piece lids can provide a tighter seal against evaporation.
- Back strip and trimming: Some hoods include a back strip or cut-to-fit features. Read installation notes to understand how to trim or apply strips for a proper seal.
- Fit guarantees and compatibility: Some listings explicitly state which brands are compatible or not. Always double-check opening dimensions and brand compatibility.
- Lighting and upgrades: If you plan to upgrade lighting, confirm whether the hood has slots or space for LED modules or additional fixtures.
FAQ
- What size should I measure on my tank for a hood?
Answer: Measure the opening length and width at the top edge, to the nearest millimeter. Do not rely on the outer case or glass thickness alone. - Are tempered glass canopies safer than polycarbonate?
Answer: Tempered glass is generally stronger for long-term use and resists impact; polycarbonate is lighter and less prone to shattering but can scratch easier. - Can I mix hoods from different brands?
Answer: It’s possible but not recommended. Fit and seal integrity vary between brands, which can lead to leaks or evaporation. - Do two-piece canopies allow better access to the tank?
Answer: Yes, two-piece designs often offer easier top-side access for feeding and maintenance while maintaining cover integrity. - Will these hoods block light or affect tank aesthetics?
Answer: Most hoods are designed to be transparent enough for observation and lighting; polycarbonate options can be slightly tinted but still clear. - Should I choose a lid with a back strip?
Answer: A back strip helps seal the rear edge and minimize evaporation, but ensure it fits your tank opening properly.
