Rotala wallichiiRotala wallichii is a slow growing, stem plant. The needle-like, delicate leaves are red in color and provide an eye-catching feature in your aquarium.Growing: difficultLight requirements: highCO₂ requirements: highAdult plant height: up to 40 cmGrowth: slowTemperature: 24 - 26°CPlacement in aquarium: second or third levelOrigin: Asia6 cm cup diameterRotala Wallichii is a demanding plant with red coloration. It is native to southeast Asia. Its Polish name is Rotala periwinkle. The leaves have the shape of fine needles. The intensity of color increases with increasing light output and is characterized by slow growth. Mature stems reach a height of up to 40 cm. The place of planting must be well planned. Faster growing plants can completely cover it. It should not be planted too densely, as the lower parts of the trunk are sensitive to lack of light. As it grows, it will form a uniform group of mature plants. The plant has a high light requirement. Strong light, fertilization and CO₂ dosage are necessary for good growth. It requires soft, slightly acidic water that is rich in carbon dioxide. Under these conditions, it thrives optimally. The exceptionally delicate appearance and subtle beauty of this plant rewards the hard work of breeding. Rotala wallichii grows well in a fertile substrate. You will get the best growth results if you plant it in an active substrate. Propagation is by shoot cuttings. Cultivation from in vitro plants is done in tissue culture laboratories. The cuttings are free from snails, algae or pathogens thanks to sterile production conditions.Planting: The plant must be removed from the cup and thoroughly rinsed from the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Divide the contents of the cup into 1-2 cm lumps and then place them on the selected items at a small distance..

PROCRISTAL UV-CCrystal clear and healthy waterPoor lighting conditions, over-fertilization or even an excess of nutrients can have a negative effect on aquarium water and promote algae. Suspended algae lead to green turbidity, bacteria to whitish turbidity. The JBL Water Clarifier removes turbidity caused by bacteria and suspended algae. The aquarium water is passed through the stable, UV-resistant housing of the clarifier. The UV-C radiation kills the bacteria, other germs and suspended algae in the water flowing through. The efficiency of this UV-C water clarifier is particularly high because the glass bulb is surrounded by a polished, reflective stainless steel foil that reflects the UV-C radiation, thus doubling the efficiency. This can also have a positive effect on the elimination of sessile algae, such as filamentous algae, as their spores are also largely killed.No harmful side effectsNo change in water values / no negative effects on important cleaning bacteria in the filter.Easy installationConnect the water clarifier to the external filter or a separate water pump. Due to the included 90° angle, any desired installation position can be achieved.SafetyThe JBL UV-C water clarifier is TÜV-tested and has a safety switch for automatic shutdown when the device is opened. The housing is UV-resistant and sturdy walls and has an LED lamp that indicates whether the UV-C burner is working.Difference from the previous model JBL ProCristal UV-C Compact:The function indicator lights are now located on the flat side of the electrical unit, and the microswitch for automatic shutdown of the burner when the housing is opened (if the plug has not been pulled out) is changed to a magnetic safety switch. As a result, the electrical units of the previous models (Compact) do NOT fit the new ones (Compact Plus) and vice versa.Crystal clear and healthy water: 18 W UV-C water clarifier for fast and efficient removal of greenish and whitish turbidity in freshwater and saltwater aquariums as well as garden ponds.Space-saving installation: connection to external filter or separate pump. Inlet/outlet opening mounted practically. Shortest installation length: 42 cmPartial disinfection up to 1500 liters aquarium (pump max. 400 l/h) /15,000 l pond (pump max. 4000 l/h), against floating algae up to 500 l in the aquarium (pump max. 500 l/h) /up to 4000 l pond (pump max. 4000 l/h)TÜV-tested, safety switch: automatic switch-off of the UV-C burner when the unit is opened.

Potassium -Potassium from Easy Life The Easy Life potassium is a macro nutrient and at least as important as iron.Potassium is used especially in areas with soft water. This manifests itself in white, discolored leaves at the growth point of a plant. Black spots can also appear on the leaves.It is recommended to add both Easy Life Ferro and Easy Life Potassium to fill up and avoid deficits especially in aquariums with many fast-growing plants. Dosage1x per week: 10 ml per 100 l water 10 ml per 100 l increases the calcium concentration with 4 ppm = 4 mg/l.

Echinodorus grisebachii Bleherae Grosse Amazonas - Schwertpflanze max. Wuchshöhe 60 - 80 cm Herkunftsland Brasilien Eignung Barschaquarium, DiskusaquariumGesellschaftsaquarium Typ Rosettenpflanze Familie Alismataceae Gattung Echinodorus Vermehrung Adventivpflanzen am Blütenstiel Wuchsgeschwindigkeit schnell pH 5 - 9 Wasserhärte 10 - 20 °dh Hinweise   Die grosse Amazonas-Schwertpflanze ist vielleicht die beliebteste Pflanze in der Aquaristik. Ihre Blätter sind mit 3-6 cm breiter als bei der ´amazonicus´ und die Wuchshöhe bis zu 60 cm lässt diese Art noch dominanter erscheinen. Ältere Büsche mit z. T. mehr als 50 Blättern sind ein imposanter Blickfang. Der Bodengrund muss aber mindestens 10 cm hoch sein, damit das Wurzelwerk sich entsprechend entfalten kann. In Kombination mit Helanthium-Arten (Zwergechinodorus) gelingen wunderschöne Südamerika-Unterwasserlandschaften.
