Seachem Nourish
Seachem Nourish Seachem Nourish™ is a comprehensive vitamin, amino acid, and trace element supplement developed to address nutritional requirements commonly associated with long term closed system housing of freshwater ornamental fish. Nourish™ contains potassium iodide in a heavy base of spirulina and chlorella. The nutrient iodine is essential for the biosynthesis of the thyroid hormones thyroxine and triiodothyronine.* Both spirulina and chlorella contain a rich assortment of amino acids and vitamins. Nourish™ can be used on marine ornamental fish; however, it is specifically designed for freshwater fish where a variety of thyroid related ailments are often encountered (especially among cichlids)

SC4517Seachem Nourish 500mL (17oz)$19.99
Seachem Flourish Iron
Seachem Flourish Iron Seachem Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement. It should be used in those cases where the iron requirements exceed that which can be delivered by Flourish™ at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins.) 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 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. Contains no phosphate or nitrate.

SC5215Seachem Flourish Iron 500 mL$9.99
Seachem Flourish Nitrogen
Seachem Flourish Seachem Flourish Nitrogen Seachem Flourish Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a nourishing system. Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant-preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen™ is complexed and unavailable until utilized by the plants. Flourish Nitrogen™ also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit use with Flourish Phosphorus™ and Flourish Potassium™.

SC5181Seachem Flourish Nitrogen 100 mL$4.99
SC5183Seachem Flourish Nitrogen 250 mL$5.99
SC5185Seachem Flourish Nitrogen 500 mL$9.99
Seachem Flourish Phosphorus
Seachem Flourish Phosphorus Seachem Flourish Phosphorus is one of the main three macro nutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a nourishing system. Flourish Phosphorus™ is a safe solution (4500 mg/L phosphate) of potassium phosphate that takes the guess work out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus™ (being nitrate free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. When used as directed Flourish Phosphorus™ will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit use with Flourish Nitrogen™ and Flourish Potassium™.

SC5293Seachem Flourish Phosphorus 250 mL$5.99
SC5295Seachem Flourish Phosphorus 500 mL$9.99
Seachem Flourish Potassium
Seachem Flourish Potassium Seachem Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. 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.

SC5195Seachem Flourish Potassium 500 mL$9.99
Seachem Flourish Excel
Seachem Flourish Excel Seachem Flourish Excel is a simple source of readily available organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be obtained via relatively simple organic compounds (such as photosynthetic intermediates). Since both processes occur simultaneously one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 injection. Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). Flourish Excel is recommended for use with the entire family of Flourish products as well as our gravel, Flourite, our GH builder, Equilibrium, and our non-phosphate buffers, Acid Buffer & Alkaline Buffer. 250 mL will treat 50 gallons for 1-2 months.

Seachem Flourite
Seachem Flourite Seachem Flourite is a specially fracted stable porous clay gravel for the natural planted aquarium. Although it may be mixed with other gravels, Flourite is best used as an integral substrate bed. Any mixture should be at least half Flourite. Gravel modifiers such as laterite are not necessary. Flourite is not chemically coated or treated, and will not alter the pH of the water. Although pre-washed, it should be rinsed before use to remove residual dust. Slight initial cloudiness is normal and will clear rapidly. Each 7 kg (15.4 lbs) bag is sufficient for about a 2 inch deep bed in a typical 10 gallon tank. Recommended use is 1 kg for about each 200 cm2 (31 in2) of tank bottom.
Item #DescriptionPrice
SC5231Seachem Flourite 15.4 lbs$14.99
Seachem Flourite Black/Sand
Seachem Flourite Black Sand Flourite™ is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. Flourite™ is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite™ is not chemically coated or treated and will not alter the pH of the water. Although pre-washed, it should be rinsed before use to remove residual dust. Dust can also be minimized by filling tank slowly and dispersing water so that the Flourite™ bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours). This bag is sufficient for about a 5 cm (2 inch) deep bed in a typical 40 L (10 gallon) tank. Recommended use is 1 kg (2 lbs) for approximately each 200 cm2 (31 in2) of tank bottom at a depth of 5 cm (2 in).
