The Fluval Edge Aquarium which we spied a little while ago has made an appearance in the UK market as a 23 liter (6 gallon) aquarium. While being a rimless tank, the top is covered with glass;Â The aquarium is designed to be filled to the brim of water allowing a top down view. Filtration, and lighting is hidden in the upper box placed on the aquarium featuring 3 stage filtration (think of eclipse systems) and lighting that leaves something to be desired with a 2 x 10 watt Low Voltage Halogen lighting system. Retail in the UK will carry a Â£119.99 ($171) price tag. This system should be available at your favorite local fish store or online UK retailer starting the second week of April.
