Aquarium Underlay Mat Diversa 120 x 40 cm — model 10958

The Diversa aquarium underlay mat 120 x 40 cm (model 10958) is a flat protective layer designed to sit between the base of a rectangular aquarium and its supporting surface. Made to match common narrow tanks, the mat evens out small surface irregularities and helps distribute the aquarium's weight across the stand or cabinet. It is intended for use with small to medium aquariums of corresponding footprint to reduce point pressure on the glass and to aid basic thermal insulation and leveling adjustments.

Advantages

The underlay mat provides a continuous cushioning layer that reduces direct contact between glass and hard stands, helping to minimise stress concentrations on the aquarium base. Its dimensions are suitable for full-coverage under rectangular tanks, improving stability and assisting with minor leveling. The material offers modest thermal separation from cold or warm surfaces and is lightweight, easy to place and remove for maintenance.

Suitable for

• Rectangular aquariums with a footprint close to 120 x 40 cm
• Home and office aquarium stands, cabinets and shelving
• Situations requiring minor leveling or reduction of pressure points on glass
• Temporary or permanent placement under glass or acrylic tanks of matching size

Key specifications

• Overall size: 120 x 40 cm
• Shape: rectangular sheet sized to cover aquarium base
• Function: cushioning, weight distribution and minor thermal separation
• Application: placed under aquarium between base and supporting surface

How to use

Place the mat on a clean, dry and level area of the aquarium stand or cabinet shelf. Position the aquarium centrally on the mat so the mat fully supports the base. Check for level and adjust stand feet or use additional shims if required; the mat helps compensate for small surface irregularities but will not level a severely uneven support. For cleaning or relocation, lift the aquarium (or drain to a safe level and remove) and wipe the mat with a damp cloth; allow it to dry before reuse.

Usage recommendations

Verify that the aquarium dimensions closely match the mat size before installation. Do not rely on the mat alone to correct major structural or leveling issues of stands. Regularly inspect the mat for compression or wear, and replace it if it no longer provides uniform support.
