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.

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 in order to force the ammonia to gas off into the atmosphere. In addition, Reef Complete® is more concentrated than any other liquid product on the market. Reef Complete® contains 160,000 ppm calcium. Our nearest competitor's product is only 110,000 ppm calcium.

MatrixCarbon is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. 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 detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use.
While carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration.
The ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate DOES NOT come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon's hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.

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 tanks 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.
