One clear sign of a disruption of this condition is the appearance of green and cloudy water. Preventive steps should be taken early on, such as using the AS 2.0 UV Sterilizer.<\/p>\n<p><strong>UV sterilizer AS 2.0 eliminates unwanted blooms<\/strong><\/p>\n<p>Green and cloudy water in the water tank is a clear sign of the presence of algae. The causes of this undesirable phenomenon can be various factors, such as overexposure of the tank to the sun or an excessive fish population. Excessive fertilizers applied to aquarium plants can also be a potential cause.<\/p>\n<p>UV STERILIZER AS 2.0 is a device designed to improve water quality and clarity in aquariums. It is an effective tool in the fight against the effect of green and cloudy water. It reduces or even eliminates the need to use chemicals for water purification.<\/p>\n<p>Operation of the AS 2.0 UV sterilizer is extremely simple. Water flowing through the device is subjected to ultraviolet light, emitted by a filament placed in a sleeve. The light damages algae, bacteria and pathogens, which are the main culprits of water turbidity and greening.<\/p>\n<p>It is important that the lamp destroys only the organisms that pass through its interior. This means that the device is completely safe for fish, other aquatic animals and beneficial nitrifying bacteria. The AS 2.0 UV sterilizer can also be useful in treating some fish diseases, even without the use of drugs.<\/p>\n<p><strong>Universal<\/strong><\/p>\n<p>The AS 2.0 UV Sterilizer is available in 4 power models:<\/p>\n<ul>\n<li>5 W for aquariums up to 200 l<\/li>\n<li>7 W for aquariums up to 400 l<\/li>\n<li>9 W for aquariums up to 600 l<\/li>\n<li>11 W for aquariums up to 800 l<\/li>\n<\/ul>\n<p>Importantly, the sterilizer is always a part of the aquarium filtration system, not a stand-alone device. Sterilizers must be connected to a pump that will pump water through the lamp. Aquael&#8217;s AS 2.0 UV sterilizer can be powered by both an external pump and a filter, and fits most models on the market.<\/p>\n<p><strong>Convenient<\/strong><\/p>\n<p>The AS 2.0 UV Sterilizer can be mounted not only outside the tank on the filter or pump hoses. If your filtration system requires it, the sterilizer can also be submerged entirely in water.<\/p>\n<p><strong>Safe<\/strong><\/p>\n<p>As you know, ultraviolet radiation (UV) adversely affects health, so when dealing with devices that use its properties, it is always essential to follow the manufacturer&#8217;s recommendations. It is worth noting that Aquael has placed great emphasis on ensuring the safety of use of the UV Sterilizer AS 2.0.<\/p>\n<p>First of all, the housing of the device is made of extremely durable plastic, which is resistant to UV radiation. Secondly, the AS 2.0 UV Sterilizer is fully sealed and meets the IPX8 protection standard. As a result, the device can safely operate in conditions of continuous immersion in water. The device is also equipped with an on\/off switch that will automatically turn off the UV-C fluorescent lamp when the lamp housing is opened, without first disconnecting it from the power source. (Not recommended by the manufacturer!). This is especially important from the point of view of protecting eyesight, which is particularly sensitive to contact with UV radiation.<\/p>\n<p>With these safety measures, users can use the AS 2.0 UV sterilizer with confidence that they are taking the proper precautions.<\/p>\n<p><strong>Easy to use and durable<\/strong><\/p>\n<p>The high durability of the UV Sterilizer AS 2.0, expressed in both the robustness of the filament and the aforementioned housing, is a guarantee that we will be able to use it for many years. Given that sterilizers usually work for a certain period of time, and the filament in the UV Sterilizer AS 2.0 allows up to 10,000 hours of operation. Should the need arise, the filament matching the UV Sterilizer AS 2.0 is constantly available from Aquael.<\/p>\n<p><strong>Energy efficient<\/strong><\/p>\n<p>The UV Sterilizer AS 2.0 is one of the few on the market equipped with an electronic ballast. It increases the life of the filament and allows significant energy savings compared to sterilizers equipped with electromagnetic ballasts.<\/p>\n<p>A lamp with an electronic circuit &#8211; such as the one used in the UV sterilizer AS 2.0 &#8211; consumes up to 50% less electricity compared to a lamp equipped with an electromagnetic ballast.<\/p>\n<p><strong>Notes<\/strong><\/p>\n<p>The product is partially made of glass and contains moving parts that may be hazardous.<\/p>\n<table width=\"621\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p><strong>UV Sterilizer AS 2.0 5 W<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p><strong>UV Sterilizer AS 2.0 7 W<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p><strong>Sterilizer UV AS 2.0 9W<\/strong><\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p><strong>Sterilizer UV AS 2.0 11W<\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Index<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>131278<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>131279<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>131280<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>131281<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Aquarium capacity [L]<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>&lt; 200<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>&lt; 400<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>&lt; 600<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>&lt; 800<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Power [W].<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>5<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>7<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>9<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>11<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Hose diameter [mm].<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>12\/16, 16\/22, 19\/25<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>12\/16, 16\/20, 19\/25<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>12\/16, 16\/22, 19\/25<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>12\/16, 16\/22, 19\/25<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Power cord length [M].<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1,9<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1,9<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1,9<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1,9<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>Maximum flow [L\/H].<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>400<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>800<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1000<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>1500<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\" width=\"131\">\n<p>UV filament lifetime<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>up to 10 thousand hrs.<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>up to 10 thousand hrs.<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>up to 10 thousand hrs.<\/p>\n<\/td>\n<td style=\"text-align: center;\" width=\"123\">\n<p>up to 10 thousand hrs.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/p>\n","protected":false},"excerpt":{"rendered":"<p>UV Sterilizer AS 2.0 11W Product highlights: Effective UV-C sterilization: Eliminates algae, bacteria and pathogens for clear and clean water.
