These are the four new sera helpers for everyday aquarium maintenance:
The fine-mesh nets made of black gauze are particularely well suited for delicate organisms and for removing leaf remainders and floating particles. They are available in four well proven sizes ranging from 8 cm (3.2 in.) to 20 cm (8 in.).
The new robust sera glass clear algae magnets convince by their ergonomic handle as well as convenient eyelets for attaching a holder line. The three available sizes can be used on glass ranging from 6 mm (0.25 in.) to 12 mm (0.5 in.).
The glass cleaner with stainless steel blade allows uncomplicated cleaning. Furthermore, the blade holder is rather flat and allows scraping off the algae in a pointed angle. The spare blades are available in packs of five in a convenient storage box.
The safety non-return valve for protecting CO2 units and air pumps is the fourth novelty. Unlike most valves available on the market, it can be dismantled and cleaned. On the inside, a silicone cone plugs up against the casing and allows the passage of CO2 or air only in one direction.
