Although planted aquariums are often considered to be too difficult for the beginning hobbyist, we believe that planted aquaria are actually ideal for the beginner.

With the right substrate the beginner can have a successful aquarium with a minimum of maintenance. As the beginner become more comfortable in the hobby they will feel inclined to experiment a bit and thus build on the solid foundation they have already established.

From our (Seachem) product line we normally recommend one start with Flourish™ and/or Flourish Tabs™. These provide a broad range of micro-nutrients (vitamins, amino acids) and micro and trace elements (iron, manganese, nickel, cobalt, etc) that will enhance plant health and growth.

If the growth rate is substantial the trace elements are often utilized more rapidly than the other components in Flourish™, thus in this case it would be beneficial to also employ Flourish Trace™ along with Flourish™ and/or Flourish Tabs™.

Once that foundation is set one can then explore the use of parameter specific supplementation.

Because plant nutrient requirements, usage rates and source water can vary drastically we have determined that the ideal approach to supplementation is to separate each component so that each can be dosed individually as needed. Sometimes these requirements can be determined by testing.

Contains no phosphate or nitrate.

Plants are able to much more easily derive a benefit from Flourish Iron™ than from EDTA-iron sources because all EDTA iron is in the ferric (Fe⁺³) state. Since plants require iron in the ferrous (Fe⁺²) state, additional physiological energy must be expended in order to extract the ferric iron from EDTA-iron and then convert it to the ferrous form.

Use 1 capful (5 mL) for each 200 L (50 gallons*) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use a test kit to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

Every organic molecule of every living organism is predominantly carbon based. Given this simple fact, it becomes clear why carbon plays a pivotal role in the planted aquarium.

Aquatic plants extract CO2 (carbon dioxide) from their environment and employ it in a process called photosynthesis. Photosynthesis combines CO2, water and light energy to produce simple carbohydrates and oxygen (O2). The first and simplest carbohydrate produced from photosynthesis is 3-phosphoglycerate. It is from this simple molecule that larger and more complex carbohydrates arise (by way of a variety of enzymatic processes).

Growth rates of aquatic plants are strongly correlated with availability of carbon and the plant’s affinity for carbon uptake. Studies1 have shown that plants with the greatest carbon affinity have the greatest growth rates, whereas those with lower carbon affinity have correspondingly slower growth rates. Because carbon availability is normally the limiting factor to growth,addition of CO2 to a planted aquarium will always result in large increases in growth (assuming other critical elements are not lacking).

Flourish Excel™ provides a simple organic carbon molecule that plants can use as a building block for more complex carbohydrates. Because Seachem’s Flourish Excel ™ is an organic carbon source it does not impact pH. The chemical structure of Flourish Excel™ is quite similar to some of the products of photosynthesis such as Ribulose 1,5-bisphosphate and 2’-carboxy-3-keto-Darabinitol 1,5 bisphosphate. Flourish Excel™ possesses the same basic 5-carbon chain seen in these molecules

Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth.

Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.

The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ by Seachem is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.

Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 2–3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.

Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Archaic fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K₂O) rather than the more scientificaly sound method of simple elemental equivalence.
