Are your aquariums suitable for both beginners and experienced fishkeepers?

Yes, our catalogue includes setups ideal for beginners—easy to install and maintain—as well as advanced systems designed for experienced aquarists. Each product page includes detailed specifications to help you choose the right option.

How do I choose the right tank size for my fish?

Larger tanks are generally more stable and easier to maintain. When choosing a tank, consider the adult size of your fish, their swimming behaviour, compatibility, space availability, and access to electricity. When in doubt, choosing a larger tank is usually recommended.

What equipment do I need to set up a new aquarium?

Most aquariums require a tank and stand, a suitable filter, a heater for tropical setups, appropriate lighting, substrate, decor, water conditioner, and a water testing kit. Many aquariums come pre-packaged with the essential components included.

Frequently Asked Questions

What is Elevate Water Block used for?

It's used to seal edges of EPDM pond or lake liner installations where extra protection against water getting in behind the liner is needed, particularly behind termination bars and around pipe flashing.

Is it safe for pond life?

Yes, it's safe for aquatic life, plants and humans, although it's a solvent-based product so should still be handled with care.

How far does one tube go?

Each tube covers approximately 3 linear metres.

Will it work with my pond liner?

It's compatible with all EPDM liners, including Firestone Elevate and SealEco.

What do I need to apply it?

A standard mastic gun, which is sold separately. Read the technical information sheet before use for full application guidance.

A solvent-based sealant for EPDM pond and lake liner installations, suitable for sealing edges and junctions that stay under continuous compression, such as behind termination bars and around pipe flashing. It protects against water tracking in behind the liner at these vulnerable points, and comes in a tube designed for accurate application with a mastic gun.

Overview Elevate Water Block is a solvent-based sealant made for sealing edges and junctions on EPDM pond and lake liner installations, compatible with Firestone Elevate and SealEco membranes. It protects against water finding its way in behind the liner at points that stay under continuous compression, such as behind termination bars and around pipe flashing. It suits anyone fitting or repairing an EPDM-lined pond or lake who needs a dependable seal at these junctions.

You get a single tube of Water Block, designed for use with a standard mastic gun so you can apply it accurately exactly where it is needed. It is formulated to be safe around aquatic life, plants and people, but it is still a solvent-based product and should be handled with care; read the technical information sheet before use for the full safety guidance and application instructions.

Key benefits It is specifically recommended for sealing behind termination bars where the liner is fixed vertically to a wall, and for the inner edge of pipe flashing around a pipe penetration. Both are points where the seal sits under continuous compression, so a formulation built to hold under that kind of sustained pressure helps keep water from tracking in over time.
