SEACHEM REEF KALKWASSER

  • Very pure calcium hydroxide
  • Ideal for increasing calcium in top-off water
  • Increases pH with no impact on carbonate alkalinity

Overview

Reef Kalkwasser™ is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural seawater levels. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium™, Reef Complete™, or Reef Calcium™, and carbonate alkalinity with Reef Builder™ or Reef Carbonate™ (do not mix these directly with a kalkwasser solution).

While Reef Kalkwasser™ is a high purity and economical limewater mix, the beginner, or someone with not as much time to devote to their system, may prefer to use other less involved methods for maintaining proper ionic concentration levels.

 

Directions

Never add this product directly to the tank. Add 3 g (1 teaspoon) to 4 L (1 US gallon) of water and mix to dissolve. If using pure water, a fully saturated solution is prepared by adding 6 g (2 teaspoons) to 4 L (1 US gallon). Drip this solution into tank. Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a stable pH (8.3–8.4). Notes: Adding 4 L (1 US gallon) of a saturated kalkwasser solution to 150 L (40 US gallons) will raise calcium by 24 mg/L. Always use the clear supernatant (top solution) only and do not allow undissolved material to enter the aquarium. Keep this container tightly closed when not in use and minimize solution/air contact to avoid calcium carbonate formation/precipitation.

Overview

Reef Dip™ contains elemental iodine complexed to a protective slime coat for safely and gently disinfecting corals. It is effective against bacteria, fungus, and protozoans. It may be used prophylactically (without evidence of disease) or to remedy diseased specimens. It is safe to use with both stony and soft corals. It is also safe for anemones and polyps. Reef Dip™ provides a protective slime coat complex that covers the coral, holding the iodine in contact with the infected site for extended periods of time. In addition, the slime coat prevents infection from re-rentering the site.
 

Directions

Do not use in the aquarium. Use in a separate container. Remove 4 L (1 US gallon) of water from the source aquarium to a container suitable for dipping. Add 5–10 mL (1–2 capfuls) of Reef Dip™ and mix. Place coral specimen in dip for 15–30 minutes, depending on severity of problem. In very severe cases, a double dose may be used. With clear and accessible lesions, dip concentrate may be painted on lesions directly before placing in dip. Observe animals during treatment for evidence of adverse reactions such as excessive sliming.

Overview

Gold Salt™ is designed to provide the optimal environment for all goldfish species. The use of Gold Salt™ also aids in the prevention of nitrite poisoning. The salt is also well suited for routine aquarium freshwater use. It does not impact pH or provide buffering. For pH control use Gold Buffer™. For dechlorination use Gold Basics™. For further goldfish environment enhancement, use Gold Trace™ to restore the proper level of trace elements and feed NutriDiet® Goldfish Flakes for thriving, healthy goldfish.

Directions

Use 18 g (1 tablespoon) for each 40 L (10 US gallons). Use when setting up an aquarium and when making water changes. To add salt to an established tank, do so gradually. It is best to dissolve the salt in a small amount of freshwater before use. Avoid using salt when replacing evaporated water.

Overview

Acid Regulator™ adjusts pH to the acidic range (4.5–5.5) and softens water by precipitating calcium and magnesium. Acid Regulator™ supports the establishment of the optimal environment for all acid acclimated species (e.g. neons and other tetras, etc.). For further freshwater environment enhancement, use Fresh Trace™ to restore the proper level of trace elements and feed NutriDiet® Tropical Flakes for thriving, healthy freshwater community fish. Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to acid pH.
 

Directions

Use 1 level teaspoon (5 g) for every 40 L (10 US gallons) daily until intended pH is reached. For precise dosing use the Seachem Digital Spoon Scale. Thereafter, use once a month or with water changes as required to maintain pH. To raise pH, use Neutral Regulator®. To target a particular pH use in combination with Neutral Regulator® following the chart. This chart assumes the use of unbuffered water (RO or DI). If water is already buffered use the chart as a starting guide. Use Prime® to dechlorinate tap water before doing a water change.

Overview

Clarity™ is the ultimate clarifier for both fresh and saltwater. It employs an advanced polymeric flocculating agent that is both reef and plant safe. Clarity™ is the only clarifier on the market that does it all! Clarity™ will clear all types of clouding. Many companies manufacture multiple products to clear up each type of cloudiness and each different environment (e.g. freshwater, marine, reef, etc.). Some companies have developed products that will clear most types of cloudiness, but their application requires two separate bottles of product. Clarity™ contains compounds that will clear all types of cloudiness in all environments.

Clarity™ contains both precipitating and flocculating agents in the same bottle, enabling all types of cloudiness to be removed in one dose.

Upon adding Clarity™ to the water, you will see a cloudy haze begin to form. This is normal and means that Clarity™ is beginning to work. The water is filled with tiny pieces of floating matter that were not visible to the naked eye. Clarity™ makes those pieces of matter begin to clump together. As they clump together they form larger pieces of matter that are now visible, hence the cloudiness. Once this matter has clumped together, it is a simple matter of mechanical filtration to remove the residue. Matter that was once too small to get caught in filter media is now in large enough clumps. In order for Clarity™ to work effectively, you should have a filter with mechanical filtration (e.g., filter floss) connected to your aquarium.
 

Directions

Use 1 capful (5 mL) for every 80 L (20 US gallons). In some situations the cloudiness may increase after adding Clarity™, however this is normal and is a sign that Clarity™ is actively working. Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears.
 

Overview

AmGuard™ safely, rapidly and efficiently detoxifies toxic free ammonia. It is safe to use during tank cycling and is ideal for treating emergency situations. AmGuard™ is the strongest liquid ammonia binder on the market. It works within minutes to detoxify free ammonia, and it doesn’t degrade for nearly 72 hours. That’s at least twice as long as our competitors’ products. Unlike competing products, AmGuard™ converts it into a safe, non-toxic form that is readily removed by the tank’s biofilter. It does not alter pH. Ammonia can exist in two forms: free and ionized. It is only the free form that is toxic. Traditional ammonia test kits convert all ammonia to free ammonia by raising pH to 12–14; at this pH AmGuard™ cannot function and thus a false positive reading will result. For long term ammonia control, use Seachem Stability® and Matrix™. Use Ammonia Alert® or MultiTest™ Free & Total Ammonia to directly monitor levels of free ammonia. AmGuard™ also removes chlorine and chloramines.
   

Directions

Use 1 capful (5 mL) for every 200 L (50 US gallons) daily or as needed to reduce ammonia. ADVANCED: If you have an Ammonia Alert® that is reading “Alert”, then use 1 capful (5 mL) for every 400 L (100 US gallons) daily. If it reads “Alarm”, then use 1 capful for every 200 L (50 US gallons) daily. If it reads “Toxic”, then use 1 capful for every 80 L (20 US gallons) daily. EXPERT: If using our MultiTest™ Free & Total Ammonia test kit, use 1 capful (5 mL) for every 40 L (10 US gallons) to remove 1 mg/L (ppm) of free ammonia. Alternatively you may employ the following formula for a variety of ammonia and water levels: 0.125AV=m (for volume in liters) or 0.5AV=m (for volume in gallons). A=ammonia concentration in mg/L, V=the volume of water being treated and m=the volume of AmGuard™ to use in mL. For example, to remove 1 mg/L of ammonia in 100 gallons you would use 0.5*1*100=50 mL. If water temperature is above 30 °C (86 °F) do not use.
