Seachem Alkaline Buffer - 250 Grams (10.5 oz) ('116023603)
250 Grams (10.5 oz)

Seachem Alkaline Buffer raises the pH and alkalinity (KH) of your aquarium water and holds it steady between 7.2 and 8.5 - an ideal range for most freshwater environments. Alkaline Buffer is safe, gentle, and phosphate-free to reduce the risk of algae or cloudiness.

  • Raises pH and increases alkalinity
  • Buffers pH between 7.2 and 8.5
  • Great for planted aquariums or very hard water

Seachem Alkaline Buffer is a sodium bicarbonate-based buffer. This makes it slightly less stable than phosphate buffers, but better suited for planted aquariums where adding more phosphates would lead to an algae problem.

Dosage:
300 grams (10.5 oz): Treats 860 Gallons
600 grams (1.3 lbs): Treats 1,720 Gallons
1.2 kg (2.6 lbs): Treats 3,440 Gallons
4 kg (8.8 lbs): Treats 11,640 Gallons

Directions: To increase pH, use 1 teaspoon (7g) for every 80 L (20 gallons) daily until the desired pH is reached (this dose raises alkalinity by about 1 meq/L (2.8 dKH)). For precise dosing, use the Seachem Digital Spoon Scale. In order to adjust pH gradually, use Alkaline Buffer with Acid Buffer.

FAQ:

  • Q: What is the difference between Neutral Regulator, Discus Buffer, Alkaline Buffer, and Acid Buffer

Even when exhausted as an organic adsorbent, SeaChem De-Nitrate continues to be an excellent support for the biological filter and does not have to be removed.

Directions: Place De-Nitrate to assure the flow of water through it, such as in a canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200 L (50 gallons) per hour. If higher flow rates are unavoidable, use Matrix or Pond Matrix. It is best to rinse off dust before use. Once De-Nitrate has been used for several days, nitrate concentrations should start to fall and level off gradually at a concentration of 4-5 mg/L as nitrate. As long as nitrate concentrations remain under control, the product is not exhausted. Each 500 mL of De-Nitrate treats about 100-200 L (25-50 gallons), depending on initial nitrate concentration and the current biological load. Enough should be used to remove nitrate at a rate at least as fast as the rate of formation. If very high nitrates are initially present, they should be brought down to less than 20 mg/L with water changes.

Seachem Purigen Ultimate Filtration Powder - 3.4 oz ('116016506)
3.4 oz

Seachem Purigen Ultimate Filtration is a premium synthetic adsorbent that, unlike any other filtration product, is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%.

  • Removes soluble and insoluble impurities from water
  • Controls ammonia, nitrites, nitrates
  • Polishes water to unparalleled clarity

Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigens impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen is designed for both marine and freshwater use.

Why Its Different:

  • Selectivity: Purigen is the highest capacity organic filtration resin on the market. No other products can compare to its ability to clear haziness and polish water to unparalleled clarity. Unlike other products on the market which are simple ion-exchange resins, Purigen is specifically designed to be an organic scavenging resin. When ion-exchange resins are filled to capacity by metals and other contaminants, Purigen has barely begun to reach its potential. Purigen generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. The primary source of nitrogenous compounds in an aquarium is waste. Fish, corals, even plants produce nitrogenous waste. Purigen removes that waste faster and more completely than anything else on the market.
  • Capacity: Purigens possesses enhanced capacity owing to its vast surface area. All other resins on the market are purely spherical extruded beads. These beads remain smooth even under a microscope. Purigen is both spherical and macroreticular. It has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.
  • Regeneration: Purigen can also be regenerated. As it adsorbs waste products, Purigen will change color from a pale blonde to a dark brown, almost black. Once it is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally ?
