The EDGE 2.0 is a six-sided glass cube you can look into from any angle, in 23 L or 46 L and black or white, with the filter, lighting and cabling hidden in the rear column. The near-sealed top is what creates that look and it is also the honest catch: Fluval's own FAQ describes the open surface area as limited, and the manual tells you to remove at least 25% of the water before putting your hands, décor or new fish into the tank. Stocking and maintenance are fussier than an open-top tank of the same volume, so it suits a light bioload and an owner who does not mind working through a small feeding door.
Filtration is a clip-on multi-stage unit with adjustable flow running foam, carbon and BIOMAX; the mechanical and biological stages are renewed with the EDGE Foam & BioMax Kit and the chemical stage with the EDGE carbon sachets. Fluval suggests 8–10 hours of light a day and low to medium light plants such as Anubias, Java fern and Cryptocoryne.
Features
- Six-sided viewing — glass on every face for a multi-angle view.
- 6500 K LED — daylight-white output for plant growth and colour, with each LED casting 120° of illumination.
- Touch switch — top-mounted, cycles day and night lighting.
- Multi-stage filtration — foam, carbon and BIOMAX with adjustable flow control.
- Feeding door — quick-access hatch in the cover, since the top does not simply lift off.
- Ventilated hood — grille to disperse heat and moisture; do not block it.
- Recessed base — elevated and set back so the tank appears to float.

Living with it
- Water changes — Fluval's manual asks for 20% weekly using a gravel cleaner.
- Before you reach in — take out at least 25% of the water first, or the tank overflows.
- Stocking guide — the manual allows a minimum of 3 L of water for every 1 cm of fish, excluding the tail.
- Algae — the inner glass wants a weekly scrub; condensation on the lid is normal and is cleaned at the same time.
- Freshwater — saltwater is possible, but Fluval notes the supplied light is optimised for freshwater.
