Seachem Reef Buffer - 9 oz
Seachem Reef Buffer - 9 oz ('116067607)

Seachem Reef Buffer raises the pH of a reef aquarium to 8.3, without the risk of accidentally raising pH to a dangerous level. It will also raise alkalinity, allowing for greater stability in a reef system where the bioload is significantly greater than in a fish-only aquarium.

  • Raises pH and carbonate alkalinity together
  • Raises pH to 8.3 without risk of accidentally over-raising
  • Allows for greater pH stability in reef systems with high bioload

Reef Buffer will raise pH and carbonate alkalinity. However, it is intended primarily to maintain a steady pH of 8.3 when pH maintenance is difficult. If pH maintenance is not an issue, Seachem Reef Builder or Reef Carbonate should be your first choice to supplement carbonate alkalinity.

Reef Buffer has a slightly higher pK than Seachem Marine Buffer. pK of a buffering agent is equivalent to the pH around which the buffer is most effective; Reef Buffers higher pK (8.6) provides greater stability in a reef system, where the bioload is greater than a fish-only system. The higher pK compensates for the organic acids produced by reef inhabitants, holding pH steady at 8.3.

Directions: Check pH and alkalinity before use. Use 5 g (1 level teaspoon) for every 150 L (40 US gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L). For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 ml (one cup) of freshwater, then add to the tank. The pH of natural sea water is 8.25–8.30. In a well established reef system, pH adjustment may be necessary biweekly to semiweekly. Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L).

If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained or substantial cloudiness that does not clear within 15 minutes is encountered, then the system is not ionically balanced. To restore ionic balance perform a water change or adjust the magnesium and calcium levels to approximately 3:1 Mg:Ca.

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

Replenishment of a number of trace elements is required to maintain an environment ideal for the growth and reproduction of marine life, but while the importance of trace elements has been recognized by aquarists for many years, the physiological reasons are not fully understood. The chemical elements in seawater are varied, and, likewise, their addition to the aquarium in trace quantities has varied effects on a variety of saltwater plants and invertebrate species. In general, though, these elements are important for metabolic processes and pigment formation.

DIRECTIONS: Use 1 capful (5 mL) for every 80 L (20 US gallons) twice a week. When used in conjunction with Reef Plus, dose on alternate days.

Seachem Reef Calcium - 8.5 oz
Seachem Reef Calcium - 8.5 oz ('116035606)

Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.

  • Maintains calcium
  • Accelerates coral growth
  • Will not alter pH

Reef Calcium may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement. Reef Calcium is intended to maintain calcium levels; if calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement to restore the depleted level of calcium.

Hikari Coralific Delite Coral Feeding Gel - 1.23 oz
Hikari Coralific Delite Coral Feeding Gel - 1.23 oz ('42055254038)

Hikari Coralific Delite is a specially formulated food that replaces zooplankton as a nutrient source for your reef aquarium corals. This revolutionary diet offers two modes of feeding: feed directly on the mouth of a specific coral, or "squirt and go," allowing coral polyps to capture the food as they would zooplankton. Either mode offers excellent polyp extension and accelerated coral growth for a stunning aquarium.

  • A nutrient package that stimulates feeding response
  • Offers excellent polyp extension
  • Dual use for maximum feeding flexibility

Coralific Delite contains the necessary nutrients inverts require, specifically: trace elements, proteins, vitamins and astaxanthin for vibrant colors. Its physical properties are similar to those of floating zooplankton, though unlike other powder-type foods, Coralific Delite will not dissolve rapidly or create cloudy water.

Feeding Instructions:
1. Targeted Gel Feeding: Mix two parts tank water to one part Coralific Delite to form a gel. Wait 3 minutes to set then use a dropper to place mixture on the mouth of the coral to be fed. Ideal for many LPS (large polyp stony corals) and sea anemone which have larger mouths.
2. Squirt and Go Feeding: Mix four parts tank water to one part Coralific Delite to form a low viscosity liquid with a creamy texture. Use a dropper to squirt food with a slow motion in the vicinity of the corals to be fed. The viscosity can be adjusted by increasing or decreasing the amount of tank water. Ideal for soft corals like horny coral and feather dusters which have a smaller mouth.

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

Ingredients: Calcium Chloride, Magnesium Chloride, Strontium Chloride.

Guaranteed Analysis:
Calcium (Ca) (min) - 335 mg; (max) - 347 mg
Magnesium (Mg) (min) - 17 mg
Strontium (Sr) (min) - 0.34 mg

Seachem Reef Advantage Calcium is a non-caustic (pH 8.3-8.6) optimized blend of ionic calcium designed to restore and maintain calcium levels to those found in natural seawater. Note that if either calcium or carbonates become deficient, coral growth will cease, followed by a rapid decline in coral health.

  • Raises calcium to natural seawater levels
  • Capable of raising 20 gallons of water by 25 ppm of calcium with only 1 teaspoon
  • Non-caustic and pH balanced (pH 8.3-8.6)
  • Maintains magnesium and strontium, will not deplete alkalinity

In addition to calcium, Reef Advantage provides magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr), helping to maintain three critical elements at once. Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. When used as directed, it will not deplete alkalinity.

Directions:
BEGINNER: Use 5 g (1 level teaspoon) per 150 L (40 US gallons) twice a week. For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 ml (1 cup) of freshwater. Check calcium every 2 weeks and adjust amount or frequency accordingly.

ADVANCED: Check calcium level, then follow addition regimen above until calcium is adjusted to 380–420 mg/L. Each 5 g/150 L will raise calcium by about 12 mg/L. Quantity or frequency can be adjusted, but do not exceed 10 g/150 L 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 to determine how much to add to your top-off water: m=vc/400 (m=grams to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 gallon=3.8 liters, 5 g=1 teaspoon].

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

Seachem Reef Complete - Raises Calcium Levels - 17 oz ('116033305)

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.
