The glass lid fits perfectly on my HCA-6G tank. It keeps the fish from jumping and reduces evaporation. The clips are sturdy and easy to install. I noticed a small gap on the sides, but it’s not noticeable in daily use. I still use an internal filter as recommended.

Works well with my tank. The glass is clear and the clips hold securely. There’s a slight gap at the back when mounted front-facing, but it doesn’t affect the overall setup. I appreciate the simple design and good fit.
