EHEIM reeflexUV reduces microorganisms in the water and eliminates torbidity more efficiently than ever before. EHEIM reeflexUV is yet another typical innovation from EHEIM: due to a built-in reflector the microorganism killing UV-C radiation is significantly increased and whereas in conventional UV-sterilisers the water is directed via detours past the UV-C burner, in the EHEIM reeflexUV water it takes the direct route. There is no loss of performance, you need less energy and. The level of effectiveness is 1.8 times greater. EHEIM reeflexUV should only be used in conjunction with the filter, in order to reduce small organisms (microorganisms, algae spores etc.) in the aquarium.

The UV-C radiation penetrates the water and kills off microorganisms, algae spores and other small organisms.Using conventional technology the water is only irradiated on one side. EHEIM on the other hand has built in a reflector, via which the reflected radiation penetrates the water from more sides. Thus reeflexUV achieves a significantly higher performance level.Furthermore, the EHEIM reeflexUV doesn’t have a complicated water flow system. The water is not redirected and flows around the burner without detours. So there is no loss of performance.The AUTO OFF ensures an optimum level of safety. Since UV-C radiation can cause damage to skin and eyes, reeflexUV switches off immediately when the device is opened.What you should also know:Compared to normal waters the bacterial count in an aquarium is relatively high due to the small amount of water. It is worth reducing this and bringing it back to a normal level. However, the aquarium water should never be completely bacteria free.Only floating bacteria in the water are captured by the UV-steriliser. Colonised cleaning bacteria in the filter (compare biological filtration) and bacteria in the gravel substrate are spared. Torbidity in the water, caused by bacteria or floating algae, is removed very efficiently by the UV-sterilisation. Basically-algae growth is curbed, because the spores are killed off.UV-sterilisers generally ensure healthier fish, because the risk of infection is reduced. A UV-steriliser is especially recommended for breeding tanks, because dangerous pathogens colonise on eggs or infect young livestock, which don’t yet possess enough power of resistance.UV-sterilisation in general doesn’t cause any kind of changes to the water values.The light source contained in this product is intended exclusively for the disinfection of aquarium water.

For operating the sera LED Tubes You can supply several LED Tubes with power when using the sera LED ballasts and the sera LED Triple Cable. You do not need a ballast for every tube but choose the one suitable for your purposes from the three ballasts. This ensures the capacity is optimally utilized and no unnecessary energy is consumed. Add the power consumption of the LED lighting and the choose the suitable ballast. Be aware that ballasts must not be overloaded when doing so.

You can use EHEIM climacontrol+ to cool down the water temperature on hot days or warm it up on cold days, just as your aquarium inhabitants need it.EHEIM climacontrol+ is our new electronically controlled climate control device. You simply set the ideal water temperature wirelessly - via smartphone, tablet, or PC/MAC. If the water is too warm, the unit automatically cools down, and if it gets too cold it warms up. The unit monitors and controls everything.Also, it gives you advanced warning of any problems, such as if the required temperature is exceeded or undershot by 2 °C for more than 5 minutes, you receive a warning e-mail.High outdoor temperatures often cause the aquarium water to overheat in summer. This is extremely harmful to fish and all other living creatures. For example if the temperature is too high, corals die in the marine aquarium, and in freshwater aquariums, oxygen deficiency and algae proliferation occur quickly.EHEIM climacontrol+ is the optimal climate control device for aquariums. It has low energy consumption and works with environmentally friendly coolant.There are three climate control devices available: S, M and L - for aquariums up to 500, 1000 and 2000 litres and come with a 3-year warranty.Features of the EHEIM climacontrol+Electronically controlled continuous flow climate control device with Wi-Fi functionalityTemperature setting and control over WiFi via smartphone, tablet, or PC/MACCooling and heating modeConstant regulation of water temperatureTemperature control of water in freshwater and marine aquariumsPrecise temperature detection from 5 °C up to 35 °CSwitches on automatically above or below a set target temperatureWarning e-mail if temperature exceeds or falls below 2 °C for more than 5 minutesConstantly displays the current water temperature when in operationUse in the ambient temperature range from 10 °C to 38 °CVery energy-efficient and environmentally friendly climate control devicewith ozone-friendly refrigerant (R290)To be operated exclusively with clean (filtered) water; i.e. for marine aquariums via separate pump with water from the filter tank or for freshwater aquariums position behind the external filter (alternatively via separate pump with pre-filter directly from the aquarium)There are three climate control devices: S, M and L - for aquariums up to 500, 1000 and 2000 litresMade of High quality parts and materials, and comes with 3 years warrantyImportant for marine water aquariums:Optimum temperature for corals between 24 and 26 °C; above 29.5 °C they die.Important for fresh water aquariums:The temperature should always be below 30 °C. Above this temperature there is a risk of oxygen deficiency, inhibited plant growth, algae proliferation.EHEIM climacontrol+ – the electronically controlled climate control devicewith WLAN function and many advantagesEHEIM climacontrol+ has the main task of cooling down the aquarium water when the temperature is too high. It provides both a cooling and a heating function.In summer, high outside temperatures often lead to overheating of the aquarium water - e.g. in a small room that heats up quickly, in an attic flat, in sunlight, etc. Even in basins that are closed at the top so that the warmth from the lighting cannot escape, there is occasionally a build-up of heat.EHEIM climacontrol+ offers WLAN function. The WiFi controller is used to set the optimum target temperature via smartphone, tablet or PC/MAC. As soon as the temperature exceeds or falls below the target value, the unit switches on and cools or heats the water until the target value is reached. The current water temperature is always displayed. If the set temperature is exceeded or undershot by 2 °C for more than 5 minutes, you will receive a warning e-mail.EHEIM climacontrol+ is a continuous flow unit and should only be operated with clean (filtered) water. For marine water aquariums, this means with water from the filter tank (with a separate pump). In freshwater aquariums by placing it behind the external filter. (Alternatively, operation via a separate pump - but with a pre-filter - directly from the aquarium is also possible here).EHEIM climacontrol+ works energy-efficiently and environmentally friendly. The refrigerant (R290) replaces ozone-depleting coolants and the global warming potential (GWP) is in the minimum range.When positioning the unit, make sure that the ventilation openings are always kept clear. The distance to walls etc. should be at least 50 mm. In the base cabinet of an aquarium combination, for example, appropriate recesses must be provided for fresh air supply and warm exhaust air (for more details, see the operating instructions).

sera gH-Test FRESH WATER , PONDWATER TESTINGCAREMakes it easy to monitor the total hardnessFor approx. 420°dGH. In case of too low GH values we recommend sera mineral salt. High total hardness levels can be lowered by mixing in R/O water. For creating soft water we recommend adding sera blackwater aquatan or filtering through sera super peat. Directions for use: Shake reagent bottle well before using! Do not allow tested water to contact aquarium or pond water!  1. Rinse the measurement vial several times with the water to be tested, then fill to the 5 ml mark. Dry the vial on the outside. 2. Add reagent drop by drop. Shake vial gently after every drop, until the color changes from red via brown to green. 3. The number of drops used from the reagent represents the existing total hardness (in °dGH). E.g., 5 drops = 5°dGH. 4. Cleaning: Clean the vial thoroughly with tap water before and after each test. Close reagent bottle immediately after use. Store at room temperature and away from light. Keep locked up and out of the reach of children. For testing ornamental fish aquariums and pond water only.  US Information for use Most ornamental fish originate from countries where the soil is poor in minerals. However, it is exactly the opposite in many other areas around the world. Rain water dissolves calcium and magnesium from the soil and consequently creates hard water. With the sera gH-Test, you can quickly determine the exact total hardness. Looking at the natural conditions helps selecting the optimal fish stock for a community aquarium, and is a precondition for successful breeding. High total hardness levels can be lowered by mixing in R/O water. A combination of sera aquatan and sera blackwater aquatan or filtering through sera super peat will create soft water, as required for most South American fish (e.g. from the Amazon basin).
