Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such hobbyist found the available solutions to aquarists’ problems wanting. This resulted in Seachem’s very first product: Cupraplex™ (today known as Cupramine™). Thirty years later Seachem is still approaching old problems in a new way. We offer truly innovative solutions that work better than competing products and save money through increased efficiency and concentration.

Seachem Ammonia Alert
Ammonia Alert™ is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.
In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.$6.95
pH Alert is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly to alert you shifts to in pH levels between 5.8 and 8.2. FRESHWATER ONLY.$6.95
Seachem Flourish TABS, 10 tab pack.
****Seachem Planted Aquarium Dosing Chart****
Flourish Tabs are growth stimulating tablets for plant roots. They contain essential trace elements, amino acids, and vitamins.
They are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots.
They contain no phosphate or nitrate that would promote algae proliferation. Each pack of ten tablets treats a 12 X 30 inch plant bed twice. For best results, use in combination with Flourish

Seachem Marine Buffer 500 gr.
Marine Buffer will safely raise marine pH to 8.3. It will not raise pH above 8.3 even if inadvertently overdosed.
Marine Buffer is a blended product and is not just sodium bicarbonate or sodium carbonate, commonly sold as a substitute. Such products can raise pH to dangerous levels if not used properly. Marine Buffer contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate.
Use Marine Trace to restore the proper level of trace elements required by thriving, healthy saltwater fish.$9.95

Reef Strontium is intended to restore and maintain strontium to levels found in natural seawater without affecting pH.
Strontium is utilized in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth.
Reef Strontium contains 10,000 mg/L of available strontium as a gluconate complex. Gluconate complexation confers several benefits: it increases the bioavailability of the strontium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it inhibits strontium precipitation/alkalinity depletion.
Gluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.$9.95

Seachem Reef Advantage Strontium 600 gr.
Reef Advantage Strontium™ restores and maintains strontium to levels found in natural sea water.
Strontium is utilized by corals in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth. It is most useful in densely populated aquariums requiring a continuous supply of strontium.
Reef Advantage Strontium™ is a highly concentrated (30,000 ppm), ionically balanced strontium supplement that can be added directly to the tank (no predissolving required).
600 g treats 20,000 L (5,000 gallons).$9.95
Reef Trace supplies a broad range of trace elements demonstrated to be necessary for proper reef health and growth.
Trace elements are normally depleted by utilization, oxidation and precipitation. The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis.
Reef Trace may be used alone or in conjunction with Reef Plus. Best results are obtained when both are used. Reef Trace is nitrate/phosphate free.
Use 1 capful (5 mL) for every 80 L (20 gallons*) twice a week.

Seachem Flourish 500 ml.
Flourish is a comprehensive plant supplement for the natural freshwater aquarium. It contains a rich assortment of important micro elements, trace elements and other nutrients.
These include calcium, magnesium, iron and other important elements that have been shown to be beneficial to aquatic plants. For macro element (NPK) fertilization, use Flourish Nitrogen, Flourish Phosphorus or Flourish Potassium as needed.$9.95
Seachem Flourish Excel 500ml.
Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates).
Therefore, 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 an integral component of Seachem’s plant products and is recommended for use with the entire Flourish™ line as well as our Flourite™ and Onyx Sand™ substrates. Contains no phosphate or nitrate.$9.95

Seachem Flourish Iron 500ml.
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.$9.95
