Fluval Flex 32.5 Aquarium Kit

The Fluval Flex 32.5 Aquarium Kit is a bold, curved-front all-in-one glass aquarium that pairs a 32.5 US gallon (123 L) tank with app-controlled LED lighting and a hidden 3-stage filtration system, giving you a complete freshwater setup in a single box. The honeycomb-print front panel conceals the water line for a clean, modern look, while the powerful Aquasky 2.0 Bluetooth LED lets you dial in custom color, dynamic effects, and a natural 24-hour cycle right from your phone. Browse our aquariums and freshwater plants to finish your aquascape.

Features

• Aquasky 2.0 Bluetooth LED. Controlled from the FluvalSmart app, with an adjustable spectrum (3,000 to 25,000 K), dynamic weather effects like storm, lightning, and cloud cover, and a programmable 24-hour timer that mimics sunrise and sunset.
• Powerful 3-stage filtration. Two independent rear media chambers pull water through mechanical (foam), chemical (activated carbon), and biological (BioMax) media for clear, healthy water.
• Bold curved, honeycomb-print design. The signature curved front glass and honeycomb wrap hide the water line and rear equipment for an unobstructed view.
• Adjustable dual output nozzles. Twin nozzles let you fine-tune flow and current to suit your fish and plants.
• Room to grow. Space to add a second Aquasky LED (sold separately) for higher-light planted layouts, plus an optional top feeder and a matching Fluval cabinet stand.

Specifications

Recommended Pairings

• Fluval Flex Aquarium Stand — a matching curved cabinet sized for the Flex 32.5.
• Fluval T Series Heater — the Flex has a built-in heater chamber but no heater; a 150 to 200 W adjustable model suits this size.
• Seachem Prime — dechlorinate and condition tap water at setup and every water change.
• Live freshwater plants — turn the honeycomb tank into a lush planted display.
• Want a smaller footprint? See the Fluval Flex 2.0 Kits (9 and 15 gallon).

Frequently Asked Questions

Can I keep saltwater in the Flex 32.5? Fluval configures and sells this kit for freshwater. For a marine setup, see our Fluval Flex Saltwater Kit, which ships with reef-ready equipment.

Does it come with a heater? No, but the rear filter chamber has a dedicated space for one. We recommend a 150 to 200 W adjustable heater for a tank this size.

Do I need a stand? A filled 32.5 gallon aquarium is very heavy, so a purpose-built stand is strongly recommended. The Fluval Flex cabinet matches the tank's curved profile.

Is it good for live plants? Yes. The Aquasky 2.0 spectrum supports low-to-medium light plants; add a second LED for high-light aquascapes.
