What types of aquariums and tanks do you offer?

We offer a wide range of aquariums and tanks suitable for freshwater, tropical, marine, and coldwater setups. Our selection includes nano aquariums, large display tanks, Betta tanks, and specialised systems designed for long-term performance in UK homes.

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.

This descaling concentrate is formulated for pond keepers whose pumps, UVC units or filter screens have started to clog with limescale, and it helps protect that equipment from ongoing mineral build-up. Made without chlorine or vinegar, it clears deposits without introducing those harsher chemicals into the pond area, and it supports a longer working life for pond pumps and filtration gear.

Overview

Oase AquaActiv PumpClean is a descaling concentrate for pond equipment, formulated without chlorine or vinegar. It's suitable for pond keepers whose pumps, UVC clarifiers or filter screens have started to clog with limescale and other mineral deposits. Breaking down this build-up helps keep pond technology running efficiently and supports a longer working life for the equipment.

Each purchase includes one bottle of concentrate, which you dilute before use to create a working descaling solution for pumps, filters and UVC equipment around the pond.

Key benefits

Because the formula contains no chlorine or vinegar, it can be used to descale pond equipment without introducing those harsher chemicals into the surrounding water. It's supplied as a concentrate rather than a ready-to-use spray, so diluting it before use produces a larger volume of working solution than the bottle size alone suggests.
