Automatic digital pH value management for CO2 operations Processes such as adding CO2 to the water rely on the pH level and can be efficiently controlled and adjusted through it. The seramic pH Controller keeps an eye on the pH levels in your aquarium and manages a connected CO2 fertilization system based on the set parameters. To achieve this, the device to be controlled is linked to the seramic pH Controller using a socket, the desired pH ranges are established, and then the seramic pH Controller autonomously and accurately manages the adjustments. The included solenoid valve can be connected to standard CO2 systems, regulating CO2 addition according to the pH levels. This kit contains: digital seramic pH Controller with power connection and external plug solenoid valve sera pH electrode 2 suction cups and universal holder universal holder plate sera test solution pH 4.0 (with safety color indicator “red”) 100 ml (3.38 fl.oz.) sera test solution pH 7.0 (with safety color indicator “green”) 100 ml (3.38 fl.oz.) 3 m (3.3 yd.) CO2 hose 4/6 non-return valve information for use Tip: The seramic pH Controller is also ideal for operating calcium reactors and dosing pumps.

Easy nighttime CO2 supply shutoff. When paired with a timer, the sera CO2 solenoid valve automatically controls the CO2 shutoff during the night or at any designated time. It is compatible with both existing and new pH-controlled CO2 fertilization systems. A CO2 pressure reducing valve should be set up between the sera CO2 solenoid valve and the CO2 gas cylinder.

Precision Pressure Reducer for External Valve A pressure reducer is essential for lowering the pressure within the CO2 bottle (approximately 50 - 60 bar / 725 - 871.2 p.s.i.) to a level suitable for supplying the aquarium (0.1 - 2.5 bar / 1.45 - 36.3 p.s.i.). The sera flore CO2 pressure reducer, featuring an integrated fine adjustment valve, is manufactured in Germany and efficiently and securely reduces the gas pressure. It is compatible with all standard CO2 bottles equipped with an external valve.

CO2 fertilizer tablets designed for the CO2 diffusion reactor, Sera CO2 Tabs are effortlessly inserted into the designated compartment of the CO2 diffusion reactor. When they come into contact with aquarium water, each tablet dispenses approximately 100 ml of CO2, which is equivalent to about 2,500 bubbles.

UV-C Sterilizer for Fresh, Sea, and Lake Water Sera UV-C systems boast universal applicability and exceptional power, making them ideal for both ponds and aquariums. UV-C radiation is not found naturally on Earth; it originates solely from space. Consequently, no organisms have adapted to withstand this intense radiation throughout evolution, including pathogens such as bacteria, viruses, fungi, parasites, and the reproductive stages of filamentous algae. This is where the UV-C system excels, enhancing the health and well-being of aquarium inhabitants when integrated into filtration systems. It effectively combats bacterial water turbidity and green water in ponds. Inside these systems, water is exposed to UV-C radiation for a brief duration. Each unit features a UV-C emitting lamp encased in a high-quality silica glass tube, which the water circulates around. The water is drawn in through a hose connector and exits via another connector on the opposite side. The variable adapter accommodates hoses of varying diameters. Changing the highly efficient PL UV-C lamp is straightforward. The end pieces with hose connectors can rotate, ensuring the shortest possible hose connection. These systems come in various capacities to meet your specific requirements (see overview). They connect to a compatible, powerful pump via a hose. Sera UV-C System 24W (UV-C Cleaner): effectively removes all types of floating algae (turbidity, green water) without chemicals, inhibits the reproduction of filamentous and other algae, and reduces the incidence of diseases and bacterial turbidity in water. This powerful yet energy-efficient UV-C cleaner features universal connections suitable for different filters and pumps. It allows for the inflow and outflow of irradiated water and the connection of hoses using variable connections. Included in the kit: 2 pieces of direct variable connections: ф 20 / 25 / 32 / 40 mm (¾” / 1” / 1¼“/ 1½”). The 24 W and 55 W UV-C systems come with a 10-meter cable. Recommended flow rates: in aquariums, 1000 – 2000 litres/hour; in ponds, 2000 – 4000 litres/hour. Please note that the UV-C system cannot operate without a pump. The inhabitants of the aquarium and the nitrifying bacteria in the filter are not harmed by UV radiation. It's essential to select a suitable pump for the recommended flow rates. Technical specifications: 220 – 240V, 50 Hz, 24W.

UV-C lamp designed for freshwater and marine aquariums up to 500 liters. The Sera UV-C systems are versatile and highly effective, making them ideal for both ponds and aquariums. UV-C radiation is absent on Earth and originates solely from outer space. As a result, no organisms have evolved to withstand this intense radiation, including pathogens such as bacteria, viruses, fungi, parasites, or the reproductive stages of filamentous algae. This is where the UV-C system comes into play, enhancing the well-being and health of aquatic life when utilized in filtration. It effectively curbs bacterial water cloudiness and green water in ponds. Product More Details Within these systems, water is briefly exposed to UV-C radiation. The unit features a UV-C emitting lamp that is encased in a durable silica glass tube, allowing water to flow around it. Water is drawn in through a hose connector and exits via another connector on the opposite side. The adjustable adapter accommodates hoses of varying diameters. Changing the highly efficient PL UV-C lamp is straightforward. The end pieces with hose connectors can rotate, facilitating the shortest possible hose connections. The systems are available in various capacities to meet your needs (refer to the overview). They connect to a suitably powerful pump using a hose. Sera UV-C systems are primarily equipped with energy-efficient lamps and a smoothly operating electronic ballast. The Sera UV-C System 5W (UV-C purifier) is also suitable for marine aquariums, effectively removing all types of floating algae without chemicals (turbidity, green water), suppressing the reproduction of filamentous and other algae, and reducing the likelihood of diseases and bacterial cloudiness in water. This powerful yet energy-efficient UV-C cleaner offers universal connections for various filters and pumps. The Sera UV-C System 5W can be used alongside the Sera P 1200 pump or connected to external bioactive filters like the Sera Serafil 130 or 250. The separate pump and tap in the filter should be capable of circulating a volume of water equivalent to that of the tank within one hour. Please note, the UV-C System 5W requires a pump to operate. Neither the aquarium's inhabitants nor the nitrifying bacteria residing in the filter are harmed by UV radiation. Universal hose connections: ф 15/20/25 mm (½”, ¾”, 1”) Technical specifications: 220 – 240V, 50 Hz, 5W
