Stability and certainty It creates a buffer and ensures the pH value It acts against biogenic descaling Creates conditions for individual species (e.g. for African Cichlids) Carbonate hardness (KH) is one of the least important parameters of aquarium water. Most fish kept in a freshwater aquarium prefer relatively harder water. In addition, KH acts as a buffer that prevents dangerous fluctuations in pH values ​​(including a sharp increase in acidity). For all community aquariums, the rule is to maintain a minimum KH of 6°dkH (significantly higher even for special cases such as African Cichlids). This ensures the well-being of the fish and the aquarium water is load-resistant and easy to maintain. Sera KH/pH-plus will increase KH accurately and long-term to the required level. The pH value will increase gently and, above all, it is safely stabilized.  

Biological filter media for phosphate removal Sera siporax algovec Professional is a biological filter medium that naturally removes phosphate with the help of bacteria. Excess phosphate can lead to increased algae growth. Bacteria using nutrients in a stable permanent form start working in a short time after contact with water and reproduce and remain active for a long time. The carrier material of sera siporax optimizes the performance of bacteria because it creates ideal conditions for settlement thanks to the structure of the surface close to nature. Preventive use of sera siporax algovec Professional will prevent phosphate enrichment.

First aid in aquariums Immediately removes ichthyotoxic ammonia and nitrite Binds heavy metals such as lead and copper Removes chlorine and chloramines Lowers nitrate levels and, correspondingly, algae growth Due to destabilizing factors (including overfeeding, high fish density, new setups, larger maintenance efforts or using treatments) massive pollution peaks by ichthyotoxic pollutants such as ammonia and nitrite may suddenly occur in aquarium water. In such emergency situations, sera toxivec immediately removes these toxic substances as well as other dangerous substances such as chlorine and heavy metals. The natural equilibrium quickly reestablishes after having removed the pollutants without the necessity of repeated stress causing large water changes.  

It breaks down ammonium and nitrite with the help of cleaning bacteria Sera marin bio reefclear, a Sera bio technology product for marine aquariums, breaks down ammonium and nitrite with the help of the contained cleaning bacteria. The mineral volcanic rock contained in it removes harmful substances, effectively binds turbidity and provides a settlement surface for cleaning bacteria. For healthy, clear and biologically active water. Recommended dosage:  Shake vigorously for 10 seconds before use and then dose immediately! A brief milky cloudiness is desirable and indicates the effect of the product. Depending on the level of impurities in the water, the turbidity will disappear in 4 to 24 hours and the water will remain clear. Dosage when setting up the aquarium: 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water. If no more ammonium is detected (e.g. with the Sera ammonium/ammonia-test) you can let the animals in. Dosage for an established aquarium: 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water per week. Dosage after changing the water or cleaning the filter: 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water. * 1 measuring cup (10 ml) filled cap up to the outer line.  

Naturally tropical black water It stabilizes a slightly acidic pH value for a long time Gently reduces water hardness Sustained release of humic acids and fulvic acids Natural chelation binds toxic heavy metals Protection against roe mold and pathogens Protective effect on skin mucus Natural protection against algae thanks to a light filter The slightly amber color enhances stress reduction Species-friendly effect of black water for tropical aquariums The natural environment of fish such as discus, angelfish or neons is characterized by very soft, slightly acidic and often dark-colored water. These so-called tropical black water conditions can be easily and long-term achieved with sera super peat. The functional granulate from natural black peat placed in the filter reduces the KH in the long term and stabilizes the pH value in the slightly acidic range. In addition, it continuously releases valuable humic acids and fulvic acid.

Soft water - but safely Lowers pH and KH Adjusts the carbonate hardness Regulates the pH value For appropriate soft and slightly acidic water Some fish species (e.g. discus and angelfish) are adapted to very soft water and require these conditions in particular for reproducing. However, the water can provide too high carbonate hardness (KH), or the pH may have risen too strongly due to natural metabolism processes, also when keeping other fish species. In these cases, sera pH/KH-minus provides reliable and quick support. The pH value and the KH are immediately and precisely lowered and regulated. This creates appropriate keeping conditions that considerably contribute to the vitality and the fish doing well. Tip: Adjust the KH to 4°dKH with sera pH/KH-minus and subsequently place sera super peat in the filter for permanently maintaining tropical softwater conditions.  

Soft water - but safely The pH and KH will drop Adjusts the carbonate hardness Regulates the pH value For species-appropriate soft and slightly acidic water Some species of fish (eg discus and angelfish) are used to very soft water and need these conditions especially for reproduction. However, also when breeding other types of fish, the water may show a high carbonate hardness (KH) or the pH value may rise too much due to natural metabolism. In these cases, sera pH/KH-minus helps reliably and quickly. The pH value as well as the KH drop immediately and are regulated. This creates species-appropriate conditions for rearing, which contributes to the vitality and well-being of the fish. Tip: Adjust KH with sera pH/KH-minus to 4°dkH and then put sera super peat in the filter to maintain species-appropriate tropical soft water conditions for a long time.  

Multitalented minerals in a complete package Improves fertility Strengthens the immune system For flawless scales and a strong skeleton The essential minerals are often insufficiently present in the confined aquarium environment. Fish take up a part of these important substances not with their food but directly through the water. Dangerous deficiencies occur whether the original water is already low in minerals (in particular R/O water) or if a dense or especially demanding animal stock in the aquarium (the plants, invertebrates and micro organisms also consume) consumes the required resources, if essential substances are missing. The excellently water soluble sera mineral salt directedly provides all important trace elements as well as valuable calcium, magnesium and potassium in pure form without any polluting additives. Tip: Due to its KH neutral behavior (only the GH is increased slightly, the KH not at all) sera mineral salt can also be used in soft water tanks (e.g. when keeping discus). Last not least for preventing the dreaded hole-in-the-head disease.

Marine salt for R/O and tap water Due to the excellent homogeneity and even grain size, sera marin salt quickly and without any residues dissolves into crystal clear marine water. It provides natural GH and KH levels, and contains plenty of calcium and magnesium in biologically correct amounts. The pH value will precisely and reliably remain in the correct range due to the natural buffer system in sera marin salt. Due to a special process, sera marin salt contains the trace elements in a way that keeps them permanently in solution and thus keeps them available for a long time. sera marin salt does not contain any substances that artificially stimulate protein skimmer activity. It is nitrate, silicate and phosphate free. Sera (sea salt without nitrates, phosphates and without silicates) contains calcium and all the trace elements necessary for the successful breeding of ornamental algae and lower resins in seawater. It contains a complex of special substances supporting the elimination of harmful substances such as heavy metals and copper. It dissolves quickly and without deposits. With a natural buffering system, it ensures an optimal constant pH value. Instructions for use: dissolve Sera marin salt (approx. 33 g per liter of water) up to a water density of 1.022 and 1.024 g/ml in a container in treated water (osmosis) or tap water without chlorine, aerate for 24 hours or mix properly with a submersible pump to reach oxygen and carbon dioxide. Warning: Do not dissolve sea salt directly in a working aquarium! We recommend changing 5-10% of the aquarium content monthly, also treating the water with sera aquatan and sera bio reef clear - you will achieve better water quality. When setting up a new aquarium, treat the water with Sera aquatan and Sera bio reef clear and let the aquarium with the connected equipment (pumps, heaters, filter...) in operation for at least 14 days to biologically stabilize before stocking it with fish.
