Plant Pack Fundamentals - 3 x 100 ml Seachem Plant Pack Fundamentals is the ideal product for beginner aquarists looking to try their hand at growing live plants in their aquarium. Combining classic Seachem products such as Flourish, Flourish Iron and Flourish Excel, these 3-in-1 pack provides everything you need to experience vibrant coloration and explosive growth, turning your aquarium into an aquatic garden. Seachem Flourish is a powerful growth stimulator designed to target aquarium plant stems and leaves. The formula contains a broad spectrum of essential trace elements, vitamins, and amino acids and contains gluconate iron, manganese, calcium, magnesium, potassium, inositol, choline B12, biotin, and other compounds proven to greatly enhance the physical development of the plants. Contains 3 100 ml bottles of each formula. Seachem Flourish Iron is made with complexed ferrous (Fe+2) iron that contains 10,000 mg/L of iron and is ideal for iron maintenance in plant heavy freshwater aquariums. These aquatic plants are able to utilize both ferric (Fe+3) and ferrous (Fe+2) iron, although for growth and development they prefer ferrous iron if it is available. Seachem Flourish Excel provides one of the most important elements regarding plant health and growth: carbon. Normally, this essential carbon is obtained through CO2, though it may also be gained from rather simple organic compounds such as photosynthetic intermediates. Due to the fact that both of these processes occur at the same time both can be used either alone or with double benefit together.
