Fluval aquarium equipment
Fluval makes aquarium equipment — filters, heaters and related kit — rather than fish themselves or fish food, aimed at freshwater and marine tank owners who want reliable, established gear for the tank itself. We stock a selection from the range, and each product page shows what is in stock right now.
Who Fluval are
Fluval is one of the more established names in aquarium equipment, with a range that spans filtration, heating and related accessories for tanks of different sizes, rather than a single product built for one specific set-up.
Equipment like this is a longer-term purchase than fish food or décor — a filter or heater is expected to run continuously for a long time, so reliability and matching the right size of equipment to your tank matter more than for a consumable.
What we stock, and who it suits
Our range includes a selection of Fluval aquarium equipment. We carry a slice of the wider range rather than every model and size, and what shows in the grid above is what is currently available to order.
It suits fishkeepers setting up a new tank who want established equipment rather than an unfamiliar budget option, and anyone replacing a filter or heater on an existing tank who wants something built to run continuously without much attention.
Choosing the right equipment for your tank
Filters and heaters are sized to a tank's volume, so check the specification against your actual tank size rather than assuming a bigger unit is always better — an oversized heater can overheat a small tank, and an undersized filter will not keep a larger one properly clean.
If you are setting up a tank for the first time, it is worth researching the specific needs of the fish you plan to keep before buying equipment, since different species have different requirements for filtration and water temperature.

Common questions
- How do I know what size filter or heater my tank needs?
- Check the equipment's specification against your tank's actual volume in litres, since undersized equipment will not do its job properly and oversized equipment can create its own problems, particularly with heaters in a small tank.
- Does Fluval make equipment for marine as well as freshwater tanks?
- The range covers equipment suited to both freshwater and marine set-ups, though not every product is designed for both, so check the specific item is rated for your type of tank before buying.
- Does Giddy Pets stock the whole Fluval range?
- No, we stock a selection rather than every model and size Fluval makes. What is shown in the grid above is what we currently have available to order, and that can change as stock does.
- How often should I service or clean aquarium filter equipment?
- This varies by filter type and tank size, so follow the manufacturer's guidance for the specific model rather than a generic schedule. Regular partial water changes and rinsing filter media in tank water, rather than tap water, are standard good practice.
- Do I need to run equipment in for a new tank before adding fish?
- Yes, most fishkeepers cycle a new tank for several weeks before adding fish, letting the filter establish the bacteria that break down waste. Adding fish to an uncycled tank is a common reason new tanks run into trouble early on.
