## Long description

Hagen Fluval Smart Silicone 2.5G is a silicone sealant formulated for aquarium use, supplied in a 2.5-gallon size for larger maintenance tasks and DIY builds. It is designed to create flexible, water-resistant seals for glass or acrylic aquarium joints and fittings, and to perform minor leak repairs while being compatible with environments that require aquarium-safe materials.
Advantages
The formula provides elasticity and strong adhesion to glass and acrylic surfaces, maintaining a watertight seal under regular aquarium conditions. Its water-resistant properties resist degradation from continuous exposure to freshwater and common aquarium additives. Provided in a large 2.5-gallon container, this silicone is suited to repeated applications and larger repair or construction projects.
Suitable for
Sealing glass and acrylic aquarium seams and corners
Repairing minor leaks in existing aquaria
Mounting or sealing fittings, bulkheads and overflow connections
DIY aquarium construction and custom tank projects
Key specifications
Volume: 2.5 gallons
Material type: silicone sealant formulated for aquarium environments
Compatibility: adheres to glass and acrylic surfaces
Performance: flexible, water-resistant seal suitable for submerged applications
How to use
Prepare surfaces by cleaning and drying the glass or acrylic to remove residue, oils and old sealant. Cut the nozzle to the desired bead size and apply an even bead along the joint or repair area. Tool the bead immediately for a smooth finish and to ensure contact with both surfaces. Allow adequate curing time according to ambient temperature and humidity before refilling the aquarium or exposing the seal to continuous water. Use appropriate safety measures such as gloves and eye protection when handling uncured silicone.
Usage recommendations
For best results, use this aquarium-safe silicone in a well-ventilated area and follow a full cure period before adding water or livestock. When sealing critical joints or large tanks, allow extended curing time and test for leaks prior to long-term use.
