Advice
Recommended as an algae stopper for all new installations. Care instructions
The hornwort is a cosmopolitan plant that can be found in many bodies of water around the world. We found the free-floating stem plant in huge populations in a tributary of the Rio Miranda on the edge of the Pantanal in South America. The growth rate of the stems is enormous, so they have to be constantly pruned. Ceratophyllum is considered a "miracle weapon" against algae growth. The explanation is quite simple: the plant is a strong nutrient consumer and removes the algae's food source. The use of hornwort is recommended for every new aquarium.Wir sind sehr bemüht, dass unsere Pflanzen gesund und unbeschädigt bei Ihnen ankommen. Trotz grösster Sorgfalt, kann es vorkommen, dass Pflanzen durch den Postversand oder andere unvorgesehene Ereignisse, leicht beschädigt sind.

JBL PROTEMP - External heater for freshwater aquariums
In-line heater integrated into the hose of the external aquarium filter, removing the need for a heater INSIDE an Aquarium
Easy installation: cut through the hose from the external filter that feeds the water back into the aquarium, insert the external heater in between, insert the plug and set the water temperature you want
This integration in the filter circuit ensures a very even distribution of the water temperature with an accuracy of +/- 0.5 °C in the aquarium

Most aquarium fish come from tropical waters and need water temperatures between 22 and 30 °C. In community aquariums with fish/invertebrates from different regions, a water temperature of 24-26 °C has shown to be effective. 30 °C is only suitable for some fish breeding (e.g. discus fish). Many shrimp species come from cooler waters and do not tolerate temperatures of 25-30°C. The water temperature should be set with a "regulated heater" which regulates the temperature automatically. For this purpose, there are rod-shaped heaters which are fixed in the aquarium (JBL ProTemp s) in various wattage and external heaters/in-line heaters which are integrated in the water-returning hose of an external filter (JBL ProTemp e) in two wattage. The advantage of external heaters is that it is one less product to be placed INSIDE the aquarium and the distribution of heat in the aquarium is more even. In addition, the digital display of the external heater always clearly shows the current water temperature. Under gravel heating is NOT used to set the water temperature. An under gravel heating cable ensures a better flow of water through the substrate of the aquarium, as the heated water at the heating cable rises and colder water flows into the areas between the heating cables. Thus, nutrients are flushed to the plant roots and ensure optimal plant growth. Under gravel heating cables must always be supplemented by a "main heater" (JBL ProTemp s or e).

Healthy fish and plantsFish depend on the right ambient temperature because, being cold-blooded animals, they are not able to adjust their own body temperatures. The vital functions of cold-blooded animals decrease with falling temperatures. The right aquarium temperature is therefore very important to ensure the animals maintain their food intake and guarantee a smooth continuation of all metabolic processes.Depending on the origin of the fish, the temperature they feel comfortable at, varies. With the practical Hang-on aquarium thermometer you can monitor the temperature in the range of 0 - 40 °C.

TÜV tested, watertight to a depth of 100 cm, unbreakable safety quartz glass with protective basket. Automatic switch-off in case of sinking water level
Heating for aquarium fishFish adapt to the ambient temperature. The life functions of cold-blooded animals sink with falling temperatures. The right aquarium temperature is therefore very important to ensure their problem-free food intake and a smooth functioning of their metabolism. Depending on the origin of the fish, the temperature they feel comfortable at varies.
Easy to installPut the heater into the protective basket included. Preselect the required temperature using the temperature dial and immerse the heater in the water at least to the “min. water level“ line. Fasten with the suction cups. A control lamp lights up as soon as the heater is connected to the power supply. The heater can also be mounted horizontally, e.g. for turtle tanks.
Ideal temperature transferJBL’s safety heater thermostat ensures an ideal temperature transfer in the range between 20 - 34 °C. With the help of the dial a control accuracy of +/- 0.5 °C is ensured. The maximum attainable temperature depends on the water volume and the difference in temperature to the surroundings.
Safety heater thermostatThe protective basket in which the heater is embedded prevents the fish from being scorched. The heater is watertight, can be immersed to a depth of 100 cm and, with its 2 mm strong safety quartz glass, is very stable. If the water level sinks or the heater is removed from the water, a safety protection device in the heater interrupts the electric current and prevents overheating. The heater is TÜV certified.

Heat cable 25WA species-appropriate temperature ratio is one of the most important factors for the well-being, health and vitality of your reptiles. That's why a heat cable from Repti Planet is an ideal solution. It is installed outside the terrarium and when connected correctly, it provides permanent heat. We recommend using a thermometer to monitor the temperature inside the terrarium. Make sure the temperature is in the right range for your species. A digital infrared thermometer is a good tool to measure the temperature in different parts of the terrarium.Different sizes availableEasy to installUse in conjunction with a thermometerInstall outside the terrariumIdeal for a longer terrarium Caution: DO NOT cut or modify the heating cable in any way. DO NOT expose the plug to water DO NOT immerse the cable in water. Not suitable for use in aquariums or aquatic habitats.DO NOT run the cable over other cable harnesses. DO NOT allow the cable harnesses to run closer than 3 cm to each other.DO NOT connect the unit when the cables are coiled together as this may cause extreme overheating and fire hazard. DO NOT operate the unit with a damaged cable, plug or other component. If the cable shows signs of damage, stop operation immediately.DO NOT alter or modify this product. Consult a qualified electrician if you are unsure of the electrical connection or components.DO NOT encapsulate the cable or bury it in the terrarium substrate.For use with glass terrariums only. DO NOT use with terrariums made of plastic, wood or other materials.Only suitable for indoor use.Keep out of reach of children.The power cable cannot be replaced. If the cable is damaged, the unit should not be used. Avoid sharp bends with a radius of less than 1.3 cm.The electrical connection must always be outside the terrarium. Plug the cable into a socket.Check regularly that the cable is still firmly connected to the glass of the terrarium. Check this at every cleaning cycle or at least once a month and apply new tape if necessary. DO NOT place the terrarium directly on a hot surface.
