Seachem Reef Calcium - 16.9 oz
Seachem Reef Calcium - 16.9 oz ('116035309)

Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Additionally, polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Reef Calcium utilizes a chained organic calcium rather than an ionic calcium. When a coral absorbs a molecule into its tissue, it uses the same amount of energy regardless of molecular size. However, charged molecules require more energy. When an uncharged molecule of Reef Calcium is absorbed, the coral acquires multiple calcium atoms as well as an easily metabolized carbohydrate with less energy expended than it uses for ionic calcium uptake. Therefore, at lower calcium levels, corals can still take in as much calcium through our organic chains as they would at much higher levels of ionic calcium.

  • Increases the bioavailability of the calcium
  • Provides a rich source of metabolic energy
  • Maintains peak coral growth
  • Prevents calcium precipitation/alkalinity depletion
  • Will not lead to algae growth in a properly maintained reef system

Directions: Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons) per day. Each capful will raise calcium by about 3 mg/L.

Seachem Marine Buffer - 2.2 lbs
Seachem Marine Buffer - 2.2 lbs ('116034708)

Seachem Marine Buffer will safely raise the pH of saltwater to 8.3, and will not raise the pH above 8.3 even if overdosed. Marine Buffer is a blended product, and contains sodium, magnesium, calcium, strontium, and potassium salts to provide effective results.

  • Safely raises and maintains saltwater pH to 8.3
  • More stable than sodium bicarbonate or sodium bicarbonate substitutes
  • Will not raise pH above 8.3 even if inadvertently overdosed

Seachem Marine Buffer is not just sodium bicarbonate or sodium carbonate (commonly sold as a substitute), as these products can raise pH to dangerous levels if not used properly. Instead it includes a variety of minerals and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate for safe, accurate dosing.

Directions: Add 5g (1 level teaspoon) for each 20 gallons (80 L). Dissolve in at least one cup of freshwater. This dose will also raise alkalinity by about 1 meq/L. Add daily until pH stabilizes at 8.3. This will take from a day to a week, depending on original pH and alkalinity. Thereafter, use biweekly or monthly to maintain a pH of 8.3. If this practice is not adequate, then overstocking, overfeeding, or other poor management practice should be sought as a likely cause. In ionically balanced marine water, Marine Buffer produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Buffer that does not dissolve within about 15 minutes, then poor ionic balance was present. A water change should be initiated when convenient before further use of the product. Effectiveness improves with continued use. Do not directly mix with any calcium, magnesium, or strontium supplement.

Seachem Reef Complete - Raises Calcium Levels - 8.5 oz
Seachem Reef Complete - Raises Calcium Levels - 8.5 oz ('116033602)

Reef Complete is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide calcium (Reef complete) and carbonates (Reef Builder or Reef Carbonate) Reef Complete also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg: Sr). This allows one to maintain these two important elements while maintaining calcium. Reef Complete is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete is blended to a higher pH to force the ammonia to gas off into the atmosphere. Also, Reef Complete is more concentrated than any other liquid product on the market. Reef Complete contains 160,000 ppm calcium.

  • Liquid Ionic Calcium Source
  • Maintains Magnesium & Strontium
  • Raises Calcium
  • Essential to Coral Growth
  • Will Not Affect pH

INSTRUCTIONS: Beginner: Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Check calcium every 2 weeks and adjust the amount or frequency accordingly

Advanced: Check calcium level (use Reef Status: Calcium to measure calcium), then follow the addition regimen above until calcium is adjusted to 380-420 mg/L. Each 5 mL/80 L (20 US gallons) will raise calcium by about 10 mg/L. Quantity or frequency can be adjusted, but do not exceed 12.5 mL/80 L (20 US gallons) per day. Thereafter, use as required to maintain calcium.

Expert: After determining the calcium consumption rate, set up a continuous drip system. Use the following formula (or skip the math and use our Dosage Calculator) to determine how much to add to your top off water: m=vc/160 (m=mL of product to add to top off water, v=volume of the tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L].

If used with Reef Calcium, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status: Calcium to measure calcium.

DO NOT OVERDOSE: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart.

Directions: Use 5 g (1 level teaspoon) for each 10 to 20 gallons of water each day until desired pH is attained and maintained. Thereafter, use as required to maintain pH, usually no more than once every two to three weeks.

Tips: It is best to dissolve the buffer in freshwater before use. Use when setting up an aquarium or making water changes (preferably after the addition of Seachems Cichlid Lake Salt) and between water changes as needed to maintain pH. Seachems Malawi/Victoria Buffer is formulated to maintain a pH between 7.8 and 8.4, depending on the amount used. To attain a lower pH than 7.8, you may use Seachems Acid Buffer in combination with Malawi/Victoria Buffer. To attain a higher pH than 8.4, use Tanganyika Buffer.

Seachem Acid Buffer - 1.2 kg (2.6 lbs) ('116024709)

Seachem Acid Buffer is a non-phosphate buffer to lower pH and buffer with Alkaline Buffer. Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem.

  • Lowers aquarium pH and buffers from 6.0 to 8.0
  • Converts alkalinity into CO2
  • For the planted aquarium or very hard water

Seachem Acid Buffer lowers pH and buffers between 5.0 and 8.0 when used with Alkaline Buffer. As Acid Buffer lowers pH it converts carbonate alkalinity (KH) into available CO2. It may also be used to safely lower pH in marine water.

Directions: To lower pH, use 1/4 teaspoon (2g) for every 80 L (20 US gallons) daily until desired pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)). Larger doses may be required in very hard (KH) or alkaline waters.
