They prevent algae growth, remove pollutants, provide hiding places and reduce pathogens.Even enrichmentThe JBL diffuser supplies the aquarium water with the main plant nutrient CO2 in even-sized bubbles.Easy to installThe diffuser is suitable for all usual CO2 systems. Connect to CO2 hose with 4/6 mm. Attach diffuser with suction holder in the aquarium.

Nesea sp. GoldNesea sp. "Gold" is a stem plant, with intense yellow to orange colors that is rare in aquarium plants. Growing difficulty: : medium, demandingLight requirement: mediumCO₂ requirement: mediumAdult plant height: 40-50 cmGrowth: mediumTemperature: 22-28°CPlacement in aquarium: third levelOrigin: AfricaCup diameter 6 cmNesea Crassicaulis Gold (Nesea sp. Gold) from Africa, a quite rare and very decorative plant with medium requirements and moderate growth rate.With sufficient light, it takes on colors ranging from bright yellow to intense orange. Nesea sp. Gold is not very demanding in terms of growing conditions. The yellow coloration of the leaves can be achieved even with moderately intense light. The stronger the lighting, the more the color shifts towards an orange tone. The plant can reach a height of up to 50 cm and is thus intended for the third level. However, it has a fairly moderate growth, so it does not require frequent pruning and with good care can be used as a foreground plant. Nesea sp. Gold needs CO₂ in gaseous form, but the carbon dioxide requirement is not too high and medium due to the growth rate is not too fast. It requires nutrient-rich water for optimal appearance. However, attention should be paid to potassium levels, as excess can cause deformation of the growth cones.It grows best at temperatures between 22 and 28 degrees Celsius. Since it prefers high temperatures, it is suitable for tanks with a population of extremely heat-loving fish. The undoubted advantage of this plant is the combination of a very unusual leaf color and low requirements. Nesea sp. Gold provides a good contrast with both green and red foliage plants, and the effect is relatively easy to achieve. It does not require a large amount of CO2. It likes soft and slightly acidic water, but can grow in other parameters as well. It needs good light, a nutrient-rich substrate, CO2 and adequate fertilization to achieve intense coloration. If you want to keep Nesea sp. Gold as a background plant, you should prune it regularly. This will not only keep it at the right height, but will also make it thicker and give it a striking appearance. After pruning, the plant will rejuvenate and the cut tops can be planted in the ground.Planting: Before planting, simply rinse the plants from the gel. Unlike plants kept in rockwool, partial drainage is not required..
