Reef Advantage Magnesium is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water.Reef Advantage Magnesium contains no ammonia! This is a common contaminant in every liquid magnesium supplement on the market.Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser.600 g treats 10,000 L (2,500 gallons).
Equilibrium is specifically designed to establish the ideal mineral content for the planted aquarium.Equilibrium contains no sodium or chloride (which can be detrimental to a planted aquarium at elevated levels). Equilibrium is ideally suited for use with RO (reverse osmosis) or DI (deionized) water or any mineral deficient water. Equilibrium raises the essential mineral/electrolyte content (General Hardness) of the water to balance with and promote stability of the carbonate hardness. To maintain KH, we recommend Alkaline Buffer. Unlike competing products, Equilibrium contains NO SODIUM CHLORIDE. Both sodium and chloride are not rapidly depleted elements in a planted aquarium, and, in the case of chloride, can do more harm than good. Competitors' products generally contain primarily sodium chloride (because it is inexpensive), which will raise the electrolyte levels for fish, but can be detrimental to plant growth. In addition, sodium is not a contributing cation to GH levels. Equilibrium contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth.Directions: To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16 g (1 tablespoon) for every 80 L (20 gallons*) when setting up an aquarium or when making water changes (add to new water). Equilibrium can be added straight, although for optimum solubility we recommend mixing with ~ 1 L (1 qt.) of water (the resulting mixture will have a white opaque appearance). When this mixture is added to the aquarium it will impart a slight haze that should clear within 15-30 minutes. HINTS: Do not use Equilibrium when replacing evaporated water. This dose is based on DI or RO water; for other water, measure hardness (GH) first, then add according to need. Plant preferences vary, but a general guide is about 1-2 meq/L (3-6 dH) or match the existing or target carbonate hardness (KH), which, ideally, is also about 1-2 meq/L (3-6 dKH).
Reef Advantage Calcium is equivalent to dry Reef Complete. It is a non-caustic (pH 8.3-8.6) optimized blend of ionic calcium designed to restore and maintain calcium levels found in natural seawater.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. Reef Advantage Calcium 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.Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity.A 500 g bottle treats 16,000 L (4,000 gallons).
Malawi/Victoria Buffer is a blend of carbonate salts designed to enhance the natural environment of cichlids by increasing hardness, buffer capacity, and pH. It is formulated to maintain a pH of 7.8-8.4. For optimum replication of the Malawi/Victoria environment, use with Cichlid Lake Salt and Cichlid Trace.Directions: Use 5 g (1 level teaspoon) for each 40-80 L (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 SeaChem's Cichlid Lake Salt) and between water changes as needed to maintain pH. SeaChem's 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 SeaChem's Acid Buffer in combination with Malawi/Victoria Buffer. To attain a higher pH than 8.4, use Tanganyika Buffer.
Seachem Flourish Excel - 4 Litre Flourish Excel is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO2 injection or Flourish Excel does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates includes compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains).Flourish Excel does not contain these specific compounds per se, but one that is quite similar. By dosing with Flourish Excel you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish Excel is able to be utilized in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others). How to Use Flourish Excel On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*). Thereafter use 1 capful for every 200 L (50 gallons*) daily or every other day. Dosing may be slowly increased in high-growth aquariums. For smaller dosing please note that each cap thread is approximately 1mL.
Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH (formulated at pH 8.2).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 inhibits calcium precipitation/alkalinity depletion. One side benefit includes enhancement of denitrification.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 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 Complete, Reef Advantage Calcium, Reef Kalkwasser).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.Each 100 mL treats up to 1,600 L (400 gallons).
Marine Buffer is the original and still unique buffer with a pK of 8.3, designed to adjust pH to 8.3 and maintain both pH and alkalinity(KH).It is formulated not to disrupt the natural ionic balance of marine water with prolonged use. Marine Buffer contains a natural balance of sodium, magnesium, calcium, and potassium salts of carbonate, bicarbonate, and borate, formulated for enhanced and lasting buffer capacity at pH 8.3 without sacrificing calcium.It dissolves readily and does not obscure water clarity. The original Marine Buffer remains clearly superior in both composition and performance and is the choice of discriminating aquarists.A 250 g bottle treat 800-1600 gallons.Marine use only.
Reef Builder raises carbonate alkalinity without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3.Carbonates and calcium are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health.Used as directed, Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity.Reef Builder and Reef Buffer may be used together.Use Reef Builder to raise carbonate alkalinity without affecting pH. Use Reef Buffer to raise carbonate alkalinity and pH.500 g treats 32,000 L (8,000 gallons).
