Even our carefully monitored tap water may contain these substances in levels that can be harmful to fish and other aquatic life. Product details Usage Sera aquatan instantly transforms tap water into a safe, healthy habitat for your fish. It effectively removes harmful agents such as chlorine and chloramines, binds heavy metals (including copper, zinc, and lead), and offers protection against ammonia. Additionally, it enriches the aquarium water with vital minerals in a form that is readily available for fish, plants, invertebrates, and beneficial microorganisms. Calcium for a sturdy, well-formed skeleton and flawless scales Magnesium for robust growth and muscle development Manganese for healthy development and enhanced fertility Iodine for balanced growth and improved disease resistance Aquatan thus fosters optimal living conditions for all inhabitants of your aquarium. Sufficient for 50 ml for 200 Liters / 53 US gallons 100 ml for 400 Liters / 106 US gallons 250 ml for 1,000 Liters / 264 US gallons 500 ml for 2,000 Liters / 530 US gallons 2,500 ml for 10,000 Liters / 2,640 US gallons 5,000 ml for 20,000 Liters / 5,300 US gallons Sera aquatan guarantees fish-friendly water by eliminating toxic ammonia and chlorine, among other harmful substances. These pollutants can be detrimental, and even lethal, to both fish and shrimp, even at low levels. The accompanying diagram illustrates the thresholds at which fish and/or shrimp may be at risk. Aquatan can efficiently remove or neutralize these pollutants within a very short period (10 minutes at most), thereby safeguarding your aquarium inhabitants from potential poisoning.

Versatile minerals in one comprehensive solution Enhances fertility Boosts the immune system Promotes healthy scales and robust skeletons Essential minerals are frequently lacking in the limited environment of aquariums. Fish absorb some of these vital nutrients not solely through their diet but also directly from the water. Risky deficiencies can arise if the initial water is already low in minerals (especially R/O water), or if a densely populated or particularly demanding aquatic environment (including plants, invertebrates, and microorganisms) depletes the necessary resources when key substances are absent. The highly soluble sera mineral salt effectively delivers all vital trace elements along with pure calcium, magnesium, and potassium, without any harmful additives. Tip: Thanks to its neutral KH properties (it only slightly increases GH while keeping KH unchanged), sera mineral salt is suitable for soft water aquariums (such as those housing discus). It also plays a crucial role in preventing the dreaded hole-in-the-head disease.

Contains essential calcium necessary for the development of coral skeletons and other invertebrates. It is recommended to use this alongside Sera marin COMPONENT 2 and Sera marin COMPONENT 1 Ca - calcium - formulated specifically for seawater. The complete series of Sera marin COMPONENT 1 - 7 is designed for advanced marine aquaristics, providing corals and various lower animals with seven beneficial ingredients that work harmoniously together. Sera marin COMPONENT 1 Ca supplies vital calcium for the formation of skeletons in corals and other lower animals. The optimal calcium concentration in water should range from 400-450 mg per liter. You can easily check the calcium levels using the sera Ca-test. When Sera marin COMPONENT 1 and 2 are combined, they help achieve the ideal pH level found in seawater and maintain the natural balance in your coral aquarium. Dosage: Use the cap as a measuring tool. Always add one capful of Sera marin COMPONENT 1 and 2 for every 100 liters of seawater, allowing a 2 to 3-minute interval between additions. It is important not to raise the calcium level by more than 20 mg/l in a single day.

Balances the pH levels in marine aquariums. Best used alongside Sera marin COMPONENT 1 Ca. The Sera marin COMPONENT 1 – 7 set is designed for serious marine aquarists, providing corals and other invertebrates with seven complementary essential nutrients. Sera marin COMPONENT 2 – Ca pH-buffer effectively stabilizes the pH in your marine aquarium. For an easy measurement of carbonate hardness, utilize the sera KH-test (refer to the testing guidelines). Dosage: Use the cap as a measurement tool. Add one capful of both Sera marin COMPONENT 1 and 2 for every 100 liters of seawater, allowing 2 to 3 minutes between each addition. Ensure that the calcium level does not increase by more than 20 mg/l within a 24-hour period.

The Sera marin COMPONENT 1 – 7 collection is designed for serious marine aquarium enthusiasts, providing corals and various invertebrates with seven essential, complementary ingredients. Sera marin COMPONENT 4 – trace elements Kationics delivers crucial trace elements to meet the everyday requirements of your aquarium's residents. When paired with Sera marin COMPONENT 3 Anionics, the delivery of trace elements to corals and other invertebrates is enhanced. Dosage instructions: Utilize the cap as a measuring tool. Weekly, add one capful of Sera marin COMPONENT trace elements 3 and 4 for every 100 liters of seawater. Prior to this, ensure that the calcium levels are adjusted using Sera marin COMPONENT 1 and 2.

The Sera marin COMPONENT 1 – 7 range is designed for advanced marine aquaristics, providing corals and various invertebrates with seven essential, complementary ingredients. Sera marin COMPONENT 6 - magnesium is rich in crucial magnesium. For optimal growth of corals and other invertebrates, it is vital to maintain a balanced ratio of magnesium and calcium. The magnesium level should not drop below 1300 mg/liter. You can easily check the magnesium concentration using the Sera Mg-test (refer to the test instructions). Dosage: Use the cap as a measuring tool. If you have elevated the calcium levels with Sera marin COMPONENT 1 and 2, incorporate one scoop of Sera marin COMPONENT 6 - magnesium for every 100 liters of water.

The Sera marin COMPONENT 1 – 7 series is designed for discerning marine aquarists, providing corals and various invertebrates with seven essential ingredients that work harmoniously together. One key component is Sera marin COMPONENT 7 - iodine, which includes the vital trace element iodine. Iodine tends to be unstable in aquarium conditions, rapidly converting to iodide, which is less effective for many aquatic animals and plants. To maintain a consistent iodine level, we recommend daily supplementation with Sera marin COMPONENT 7 - iodine. This approach helps to avoid fluctuations in iodine concentration and prevents deficiencies. Sera marin COMPONENT 7 - iodine is packaged in a convenient dropper bottle for easy dosing. Recommended dosage: Add one drop of Sera marin COMPONENT 7 - iodine for every 100 liters of water, ideally after using Sera marin COMPONENT 5 - strontium.

Soft water - but in a safe way Lowers pH and KH Adjusts the carbonate hardness Regulates the pH level For suitable soft and slightly acidic water Certain fish species, such as discus and angelfish, thrive in very soft water and particularly need these conditions for successful breeding. However, the water may have too high a carbonate hardness (KH), or the pH might have increased excessively due to natural metabolic processes, especially when housing different fish species. In such situations, sera pH/KH-minus offers effective and swift assistance. The pH and KH are quickly and accurately reduced and regulated. This establishes optimal conditions that significantly enhance the vitality and overall well-being of the fish. Tip: Set the KH to 4°dKH using sera pH/KH-minus, and then add sera super peat to the filter to maintain tropical soft water conditions permanently.

Stability and Reliability It provides a buffer and maintains the pH level. It counteracts biogenic scaling and creates optimal conditions for specific species (for instance, African Cichlids). Carbonate hardness (KH) is among the less critical parameters of aquarium water. Most fish in freshwater aquariums thrive in relatively harder water. Furthermore, KH serves as a buffer that helps to prevent dangerous fluctuations in pH levels (including a sudden rise in acidity). For community aquariums, it is advisable to maintain a minimum KH of 6°dkH (even higher for special cases like African Cichlids). This ensures the health of the fish and keeps the aquarium water resilient and easy to care for. Sera KH/pH-plus will accurately and sustainably elevate KH to the desired level. The pH will increase gradually and, more importantly, will be securely stabilized.

It effectively breaks down ammonium and nitrite, utilizing specialized cleaning bacteria. Sera marin bio reefclear, a product of Sera bio technology designed for marine aquariums, works to eliminate ammonium and nitrite with the aid of these beneficial bacteria. The inclusion of mineral volcanic rock helps to eliminate harmful substances, efficiently binds turbidity, and offers a surface for the cleaning bacteria to thrive. This ensures your water is healthy, clear, and biologically active. **Recommended dosage:** Shake well for 10 seconds before applying and then dose right away! A brief, milky cloudiness is expected and indicates the product is working. Depending on the level of impurities in your water, turbidity should clear up within 4 to 24 hours, leaving your water crystal clear. **Dosage for setting up the aquarium:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. Once ammonium levels are undetectable (for instance, confirmed with the Sera ammonium/ammonia test), it’s safe to introduce your aquatic animals. **Dosage for an established aquarium:** Administer 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water once a week. **Dosage after water changes or filter cleaning:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. *1 measuring cup (10 ml) should be filled to the outer line.
