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.

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.
