Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year and replacement sensors are available. Marine or freshwater use.In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.

Seachem Flourish Excel - 500ml 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.

Flourish Tabs are growth stimulating tablets for plant roots. They contain essential trace elements, amino acids, and vitamins. They are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots. They contain no phosphate or nitrate that would promote algae proliferation. Each pack of ten tablets treats a 12 x 30 inch plant bed twice.Perfect for the beginner, Flourish Tabs contain all the nutrients found in Flourish in a dry, tabular form. These tabs are inserted into the gravel, providing direct, time-released fertilization to the plants' root zone. Nutrients are slowly made available through enzymatic action of the plants' roots on the tabs.Directions: Insert one Flourish Tab in the gravel for every 10-15 cm (4-6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed. Push each tablet midway into the gravel bed. Add new tablets once every one to three months for optimal plant growth. Tabs will not alter pH, but, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.

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).

Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium.Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.Directions: Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 2-3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.Derived from: Potassium Sulfate. Elemental potassium is present at a concentration of 50,000 ppm (e.g. 5%). Archaic fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientifically sound method of simple elemental equivalence.

Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement. It should be used in those cases where the iron requirements exceed that which can be delivered by Flourish at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins.) Contains no phosphate or nitrate.Plants are able to much more easily derive a benefit from Flourish Iron than from EDTA-iron sources because all EDTA iron is in the ferric (Fe+3) state. Since plants require iron in the ferrous (Fe+2) state, additional physiological energy must be expended in order to extract the ferric iron from EDTA-iron and then convert it to the ferrous form.Directions: Use 1 capful (5 mL) for each 200 L (50 gallons*) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use MultiTest: Iron test kit to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

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 (formulated at pH 8.3).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 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 delivers 560x more calcium than is available from an equal volume of kalkwasser solution. Use Reef Complete to maintain adequate calcium and Reef Calcium to promote accelerated growth.500 mL treats 8,000 L (2,000 gallons).

StressGuard is the premium slime coat protection product. StressGuard will reduce stress and ammonia toxicity whenever handling or transporting fish. StressGuard binds to exposed protein in wounds to promote healing of injured fish and to reduce the likelihood of primary and secondary infections.StressGuard is compatible with all medications except those that are copper based. StressGuard is not amine based and will not interfere with Purigen or HyperSorb regeneration. StressGuard does not coat resins or clog filtration like competing "slime coat" type products can.What makes StressGuard very successful at healing is the fact that it contains protein active colloids. This protein active colloidal agent actively seeks out any wounds, abrasions, or places where exposed proteins are and attaches to this area to help directly deliver the disinfectant in the product and start the healing process. This protein active colloid, because it binds to the exposed proteins, also acts like a liquid bandage to the abrasion.Some products are marketed to be squirted in the bag when a fish is purchased. Those products are generally acidic, with some brands being a very strong acid. Putting such a product in a small, enclosed container with a fish often does more harm than any intended good. StressGuard has a pH of 7.0. It will not affect the pH of an aquarium, even at large doses. There are no other products on the market that can compare to the effectiveness of StressGuard.Directions:Use 1/2 - 1 capful (2.5 - 5 mL) to every 40 L (10 gallons*) daily until signs of stress have abated or healing is complete. Dose may be safely doubled.

Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. This calcium hydroxide meets or exceeds the purity of competing brands designated for reef use.Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that are used in an automated dosing system that replaces evaporated water.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 the 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).Reef Kalkwasser can also precipitate phosphates and impurities from the makeup water while maintaining a high pH which is important for proper calcification rates and for oxidizing various organics in reef aquaria.500 g makes 650 L (166 gallons) of kalkwasser solution.

Pristine uses bio-augmentation, a non-chemical and natural method, to improve water quality. It provides bacteria that break down excess food, waste and detritus in freshwater and marine systems. It will also reduce excess nutrients (e.g. ammonia, nitrates, and nitrites) that may fuel the growth of nuisance and disease-causing organisms.Pristine increases water clarity and promotes overall better health for the aquatic environment.The bacteria species in Pristine thrive in fresh or salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike traditional nitrifying bacteria, this bacterial blend can adapt to harsh or low oxygen environments and continue to multiply and improve water conditions. Biopolymers produced by established bacterial colonies trap particulates and increase water clarity.The species of bacteria in Pristine are a unique blend, specifically developed for hardiness and their ability to adapt to a wide variety of environmental conditions.DirectionsShake well before use. Turn off UV/ozone. Use 1 capful (5 mL) for each 40 L (10 US gallons). Then use a maintenance dose of 1 capful (5 mL) per 80 L (20 US gallons) with additions of livestock or the disruption of the biofilter through cleaning or medications. Antibiotics should be removed with fresh carbon and a water change before adding bacteria. Allow 2 or 3 days for the bacteria to become established before using UV sterilizers or ozone. Recurring problems with high nutrients can indicate overstocking, overfeeding or inadequate filtration.

Reef Trace supplies a broad range of trace elements demonstrated to be necessary for proper reef health and growth.Trace elements are normally depleted by utilization, oxidation and precipitation. The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis.Reef Trace may be used alone or in conjunction with Reef Plus. Best results are obtained when both are used.Reef Trace is nitrate/phosphate free.

Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste.Matrix is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix provides as much surface (>~700 m2) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix provides both external and internal macroporous surface area.These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.Matrix is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix may be rinsed when needed without damaging the filter. Matrix is compatible with all types of wet or wet-dry filters.

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).

Flourite Black is a specially fracted, stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment.Flourite Black is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite Black is not chemically coated or treated and will not alter the pH of the water.Although pre-washed, it may be rinsed before use to remove residual dust. Dust can also be minimized by filling aquarium slowly and dispersing water so that the Flourite Black bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2-12 hours). To shorten the cloudiness period use Clarity in conjunction with mechanical filtration (such as filter floss).

The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis. Flourish Trace may be used alone or in conjunction with Flourish. Best results are obtained when both are used.Flourish Trace is different by separating the minerals out into a separate product, one can dose it on a more frequent basis than a broad spectrum supplement without worrying about a build up of the more slowly used components. Directions: Use 1 capful (5 mL) for every 80 L (20 gallons*) twice a week.

MatrixCarbon is a truly unique activated carbon, bead shaped for optimal hydrodynamics. This provides maximum water flow and contact with a high density of adsorptive sites without the compacting common to granular activated carbon.MatrixCarbon has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0.While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon has the lowest leachable phosphate content of all major carbon brands tested.It out-performs other best grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use. 250 mL will easily treat 100 gallons for several months.It is very clean and nearly dust free.Marine or freshwater use.
