planted aquariums. It contains all the nutrients that freshwater plants require to grow except phosphorus and nitrogen. Phosphorus is rarely required in any aquarium unless no animals are present at all. Nitrogen may be required for very rapid plant growth in the heavily planted aquarium or in the case of very light fish load. If your aquarium requires nitrogen or for accelerated plant growth, simply use our Flora Viv Grow. Flora Viv products contain no dangerous polycycloglutaracetal or glutaraldehyde. Simultaneous use of Bacter Gen F to establish and sustain growth of proper microorganisms and recycle aquarium nutrients will greatly benefit all plants and the ecosystem in general. The use of Flora Viv Prolifera will provide additional carbon for heavily planted aquariums. Growth of all photosynthetic organisms also requires strong lighting of proper spectrum. Consult your lighting supplier for assistance in the proper type of light, and photo periods for the plants that you are growing
