Bolbitis heudelotii or African Water Fern - aquarium plant belonging to the family of Polypodiaceae.
Birthplace Bolbitis heudelotii are West African tropics from Angola to Guinea. Common in slow flowing rivers and along waterways .
Bolbitis heudelotii creeping rhizome brownish, which runs lateral roots. Rhizome can grow to a solid object. Leaves alternate location. In form, dark green leaves complex, cirrus. At length grow to 30-50 cm during the year is aquarium plant grows slowly, but under favorable conditions grows evenly.
The content Bolbitis heudelotii fastidious and demanding. But it survives well in warm temperate and tropical aquarium. The temperature at which the fern will feel comfortable, should not exceed 26 °C. Above this temperature the plant is quickly exhausted and dies. If the temperature drop to 20 °C, the plant will slow its growth. As a means of lighting is possible to use lamps with a filament or fluorescent type LB. Daylight Bolbitis heudelotii should be about 12 hours. He perfectly transfers as darkening, and feels good in diffuse daylight. However fern should be protected from direct sunlight. Bolbitis heudelotii be contained in a weak acidic water (pH 6-7 ) as leaf plants in alkaline water tend to decay faster. Hardness of the water in the tank about 6 ° - the maximum allowable. Best plant will grow with stiffness 4 °. Bolbitis heudelotii needs regular mineral supplements, especially when scarce organic matter at the bottom. In the fertilizer must necessarily contain trace elements. Such complex mineral supplements are made every week and are generally dosed so - 1-2 grams per 100 liters of water. But feeding the plant, do not forget that it does not like saturated sodium water. Therefore, the addition of baking soda or salt should be minimized ( to 1 liter of water is not more than 1 g). Growing Bolbitis heudelotii possible without soil : roots - rock rhizoids envelop planted like network. This aquarium plant dense enough to sink into the water and do not float. Optional, but the content of plants favorable condition is the presence of sludge in the tank bottom. But for good plant growth and development is necessary to make sure that did not happen fouling fern green and blue- green algae ( this , incidentally, is the need protect plants from direct sunlight).
