Minerals and Trace Elements for Invertebrates Reduces molting issues Boosts the reproduction rate Supports healthy growth Enhances the immune system Improves mineral-poor R/O water Shrimps and other aquatic inhabitants absorb some of their necessary minerals and trace elements directly from the water, rather than solely through their diet. Unfortunately, aquarium water often lacks sufficient quantities of these vital substances. sera shrimp mineral salt delivers all the essential trace elements along with important calcium, magnesium, and potassium in a targeted manner. This effectively prevents molting issues and reliably fills the nutrient gaps.

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.

This test allows for easy and accurate monitoring of calcium levels in increments of 20 mg/l (ppm) for approximately 7,500 mg (ppm) of calcium. If calcium levels are found to be too low, add sera marin COMPONENT 1 Ca. For levels that are too high, performing a partial water change will be beneficial.

Marine salt for R/O and tap water Thanks to its exceptional consistency and uniform grain size, sera marin salt dissolves swiftly and leaves no residues, resulting in crystal clear marine water. It helps to establish natural GH and KH levels, while being rich in calcium and magnesium in biologically suitable proportions. The pH value is kept stable and accurate, thanks to the natural buffering system found in sera marin salt. Through a unique process, sera marin salt retains trace elements in a manner that keeps them consistently dissolved and available for extended periods. This salt does not include any substances that could artificially boost protein skimmer performance. Moreover, it is free from nitrates, silicates, and phosphates. Sera (sea salt without nitrates, phosphates, and silicates) is rich in calcium and all essential trace elements required for successfully cultivating ornamental algae and lower resins in seawater. It contains a blend of special substances that aid in the removal of harmful elements such as heavy metals and copper. The salt dissolves rapidly and without leaving deposits. With its natural buffering capability, it ensures an optimal and stable pH level. Instructions for use: Dissolve Sera marin salt (approximately 33 g per liter of water) to achieve a water density of 1.022 to 1.024 g/ml in a container using treated water (osmosis) or chlorine-free tap water. Aerate for 24 hours or thoroughly mix with a submersible pump to introduce oxygen and carbon dioxide. Warning: Avoid dissolving sea salt directly in an active aquarium! We suggest replacing 5-10% of the aquarium water monthly and treating it with sera aquatan and sera bio reef clear to enhance water quality. When setting up a new aquarium, treat the water with Sera aquatan and Sera bio reef clear, and allow the aquarium, along with the connected equipment (pumps, heaters, filter...), to run for at least 14 days to ensure biological stabilization before adding any fish.
