Learn step-by-step how to safely replace a broken aquarium glass cover panel, including tips for Superfish Qubiq 60 tanks and sourcing the right spare parts.

Quick answer

To replace a broken aquarium glass cover, measure your tank rim, order the correct replacement panel, and follow a safe removal and installation process. For Superfish Qubiq 60 tanks, use the dedicated cover glass to ensure a perfect fit.

Why use a dedicated replacement panel

Standard glass panels may not align with the rim clips or hinge slots of your specific tank model. A dedicated replacement, such as the Superfish Qubiq 60 Cover Glass, is cut to the exact dimensions and includes the correct edge profile for a secure seal.

Using a mismatched panel can leave gaps that allow evaporation, debris, or even fish to escape. It may also stress the tank rim, leading to cracks over time.

What to check before ordering

Confirm your tank model and measure the rim opening length and width. Even within the same brand, different models use different glass sizes. For the Superfish Qubiq 60, the cover glass is designed specifically for that tank – the manufacturer only guarantees compatibility with that model.

Also note that the product image may be a placeholder; the actual glass panel will match the specifications listed, not the picture.

Step-by-step replacement process

1. Remove the old glass safely: Unplug all aquarium equipment. Gently lift the old cover glass from the rim clips or hinges. If the glass is cracked, wear gloves and use tape to stabilise the break before lifting. Place the broken panel in a cardboard sheet for disposal. Never force a cracked panel – it may shatter. If it resists, check for stuck clips first.
2. Clean the rim and clips: Wipe the tank rim, hinge slots, and clip channels with a damp cloth to remove salt creep, algae, or debris. Dry thoroughly. This ensures the new glass sits flush and seals properly. Leftover grit can scratch the new glass or prevent a tight fit.
3. Inspect the replacement panel: Unpack the new cover glass and check for chips, cracks, or warping. For the Superfish Qubiq 60 Cover Glass, verify that the dimensions match your tank rim (the product is designed specifically for that model). If anything looks off, contact the seller before installing. Do not install a damaged panel – even a small chip can spread under the weight of lighting or condensation.
4. Position and secure the new glass: Lower the new cover glass onto the rim clips or hinge slots. Press down gently until it clicks into place. Ensure the glass is level and does not rock. For tanks with a rear cutout for filters, align that opening before pressing down. If the glass does not seat evenly, remove it and check for debris or misaligned clips – do not force it.
5. Test the fit and restore equipment: Reconnect lighting, heater, and filter. Turn on the equipment and check for any gaps around the cover. Run the system for an hour and inspect for excessive condensation or moisture escaping from the edges. A small gap near the filter cutout is normal, but large gaps indicate the wrong panel size.
