Oxygenating Plants
Oxygenating plants photosynthesise underwater creating oxygen which dissolves in the water. This is not only useful for animal life but also for bacteria which help keep the water clean. Bunches of oxygenators can be dropped into the water but ideally are planted in groups of 3 or more using gravel or aquatic soil in a basket up to 100cm deep. Many oxygenators grow best in streams or rivers so planting in gravel helps them acclimatise quicker.
