The Aquael Optibent Set 20 l set is a fully equipped and design-oriented aquarium set. Thanks to the rounded corners, the uniqueness of the underwater world can be ideally displayed from every perspective. The material used, Opti-Glass, is highly transparent and of high quality. For the filtration, temperature and lighting of the aquarium, the set includes ideally matched accessories from Aquael.

The scope of delivery of the OptiBent set includes the aquarium tank and a cover made of Opti-Glass. The fronts of the Optibent aquariums are made of one piece of glass and therefore have no disturbing silicone joints at the front.
The supplied Aquael Fan Filter Mini can be varied in flow rate, aeration and water flow direction and is thus ideal for flexible use in nano aquariums.
The electronic aquarium heater Ultra Heater 25 is protected by a break-resistant plastic housing and equipped with the Smart Heating System for independent adjustment of the heating power to the ambient conditions.
The Leddy Slim Duo Sunny & Plant Day & Night lighting combines the two lighting spectra "Sunny" and "Plant". With a colour temperature of 7.000 Kelvin, the "Sunny" spectrum is modelled on daylight and enables optimum reproduction of the colours of the aquarium. The "Plant" spectrum with 9.000 Kelvin ensures fast and strong plant growth. In addition, the luminaire has 3 operating modes:
Day (Sunny = 100 % output + Plant = 100 % output), Daybreak (Sunny = 50 % output + Plant 50 % output + Night = 100 % output) and Night (Night = 100 % output). Day is a basic lighting mode with the highest intensity for lighting the aquarium during the day. Daybreak works well as a twilight mode and is ideal when feeding fish - especially shy stock. Night mode, with blue light, allows unique observation of the aquarium even after sunset and is also optimal for nocturnal animals.
A foam base compensates for the slightest unevenness of the installation site and reduces stress on the glass. In addition, the aquarium is thermally insulated from the subfloor.
