The Tetra Starter Line aquariums are ideal for all newcomers to the world of fishkeeping. They not only come in two different sizes (30 and 54 litres) but also with helpful features and all the essential technical equipment. The smaller model is particularly ideal for crustaceans and plants, whereas the medium-sized aquarium makes the perfect home for guppies, platties and co. Not only are the aquarium tanks particularly sturdy, but their four-millimetre-thick panes are also made from special float glass to offer you an undistorted view of your aquatic creatures from all angles. In addition to this, the aquarium lid is also particularly robust, so crustaceans that love to climb cannot escape, for example. A practical feeding flap in the lid enables you to easily feed your fish without having to remove it entirely. The six watt LED light integrated into the lid illuminates your aquarium with bright, natural light while also being extremely energy efficient and durable. The Tetra EasyCrystal Filter also provided in the set keeps the water clean and crystal clear by reliably eliminating dirt and algae. This functions as follows: with biological filtration, useful bacteria can settle on the biological filter balls and filter sponge. With mechanical filtration, on the other hand, a filter fleece removes even the tiniest floating particles from the water. And the replaceable filter cartridges mean you never have to spend ages cleaning the filter housing. The cartridges are easy to insert – without even getting your hands wet! For optimum water quality, you should replace the cartridges every four weeks. The set contains one spare filter cartridge. The simple set-up and impressive technical equipment therefore make a Tetra Starter Line aquarium the ideal choice for any newcomer to the world of fishkeeping.
