  • Seachem MultiTest Ammonia Test Kit

    This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system.This kit is based on the same gas exchange technology that is used in the Ammonia Alert® and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime®, Safe™, AmGuard™ and any similar competing products. The other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading.

  • Nitrite & Nitrate Detoxifier Seachem Safe for Marine & Freshwater Aquariums, 2.2-ib jar

    Seachem Safe Nitrite & Nitrate Detoxifier for Marine & Freshwater Aquariums is a complete and concentrated dry conditioner for both marine and freshwater aquariums. It removes chlorine and chloramine, and detoxifies ammonia converting it into a safe, non-toxic form that is readily removed by the tank's biofilter. Safe may be used during tank cycling to alleviate ammonia and nitrite toxicity. It detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. Safe is non-acidic and will not impact pH. Use at startup and whenever adding or replacing water.

  • Marine Buffer, 20 kg / 44 lbs

    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 Seachem’s MultiTest™: Marine pH & Alkalinity to check pH and total alkalinity. Use Marine Trace™ to restore the proper level of trace and feed NutriDiet® Marine Flakes for thriving, healthy saltwater fish.Total Alkalinity is a measurement of three main ions: carbonate, bicarbonate, and borate. In saltwater, bicarbonate drives the pH toward 7.8, carbonate drives pH toward 9.1, and borate toward 9.5 or more. Because of the chemistry of buffering systems, the closer you get the pH to the pK of a buffering system, the harder it is for the pH to shift. So, if you blend a buffer so that the combined product drives the pH toward 8.3, then the more you use, the more stable the pH becomes. That is the principle behind Marine Buffer™. It is a blended buffer that drives and holds your pH at 8.3 because of th...
