sera guide - How to set up an aquarium according to nature

34 Many situations in an aquarium require air. Therefore you need a powerful air pump, e.g. for air-driven • airstones • filters • gravel cleaners • gravel washers The sera air 110 plus has one, the air 275 R plus two, and the 550 R plus four outlets with an always absolutely independent membrane system. Therefore the sera air plus pumps are ideally suitable for supply- ing more than one aquarium with only one pump. The sera air 275 R plus and 550 R plus are electronically adjustable – there is no complicated and less precise adjustment by valves and hose clamps. The pumps of the sera air plus series are excellently man- ufactured and bear the TÜV/GS and CE Signs. The especially thick-walled and noise- absorbing casing consists of shockproof and long lived ABS material, superior to PVC and similar plastic. Elastic standing feet ensure permanently quiet use with little vibration. Airstones and connection to air-operated devices The sera air set “S” is ideal for use with the sera air 110 plus. It contains two meters (2.2 yd.) of silicon hose, which is much more flexible and durable, compared to custom- ary hoses. Also, it contains an appropriately sized airstone, a regulator and a non-return valve. The sera air set “M” suits the sera air 275 R plus. Four meters (4.4 yd.) of silicon hose, two airstones, two non-return valves, and one regulator allow the independent use of two aquarium decorations or an air-oper ated filter such as the sera L 150 or L 300.
