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.  

  Herbal water conditioner against skin and gill flukes The herbal water conditioner sera Phyto med Tremazid contains highly effective and natural peppermint oil as an agent for treating skin and gill flukes in fresh and marine water as well as in ponds. Synthetic agents such as chlorine containing substances, are not included. sera Phyto med Tremazid has no effect on the biological filtration, it is very well tolerated, can be broken down biologically and does not cause bacterial cloudiness of the aquarium water. Adjusting water parameters and a water change afterwards are thus not required.

Highest quality premium marine salt similar to nature The new sera marin reef salt is a highest quality premium marine salt similar to nature for splendid reefs. It is blended from single components and ensures pollutants can by all means be excluded. The constantly high quality reduces stress during water changes. Even the requirements of the most fastidious invertebrates, such as stony corals, are being fulfilled. Deficiencies are efficiently avoided. sera marin reef salt contains all required macro and trace elements, which in marine organisms have key functions in the skeleton growth of invertebrates and in the production of enzymes and color pigments. Easily and quickly soluble due to fine grain size and using pure single components.

The set of Sera marin COMPONENT 1 – 7 preparations is intended for demanding marine aquaristics, it supplies corals and other lower animals with seven valuable ingredients adapted to each other. Contains important magnesium Sera marin COMPONENT 6 - magnesium contains important magnesium. Magnesium and calcium must be in a balanced ratio for optimal growth of corals and other lower animals. The magnesium content should not be lower than 1300 mg/liter. You can conveniently determine the magnesium content using the Sera Mg-test (see instructions for the test) Dosage: Use the cap as a measuring cup. If you have increased the calcium content with Sera marin COMPONENT 1 and 2, add one scoop of Sera marin COMPONENT 6 - magnesium per 100 liters of water.  

Permanent phosphate removal The important plant nutrient phosphate is required only in small amounts. An over-supply creates algae problems. sera phosvec Granulat removes phosphate easily and safely with long-term effects. The granules remain active up to three months, according to the aquarium size and the water pollution. Suitable for filtration of fresh and marine water.

The set of Sera marin COMPONENT 1 – 7 preparations is intended for demanding marine aquaristics, it supplies corals and other lower animals with seven valuable ingredients adapted to each other. It contains the important trace element iodine Seramarin COMPONENT 7 - iodine contains the important trace element iodine. Iodine is not stable in the aquarium for a long time, it quickly turns into iodide; it is not that effective for most animals and plants. We maintain a constant iodine content by daily addition of sera marin COMPONENT 7 - iodine. This is how you prevent fluctuations in concentration and lack of iodine. Seramarin COMPONENT 7 - iodine is in a bottle with a dropper, which allows convenient dosing. Dosage: It is ideal to add one drop of Sera marin COMPONENT 7 - iodine per 100 liters of water after adding Sera marin COMPONENT 5-strontium  

The set of Sera marin COMPONENT 1 – 7 products is intended for demanding marine aquaristics, it supplies corals and other lower animals with seven valuable ingredients adapted to each other. Sera marin COMPONENT 4 – trace elements Kationics - (trace elements of cations) supplies important trace elements for the daily needs of aquarium inhabitants. In combination with Sera marin COMPONENT 3 Anionics, the supply of trace elements to corals and other lower animals is optimized. Dosage: Use the cap as a measuring cup. Once a week, add one cap of Sera marin COMPONENT trace elements 3 and 4 per 100 liters of seawater. But before that, adjust the calcium content of Sera marin COMPONENT 1 and 2.  

Clear sight Removes mineral cloudiness Removes the main algae nutrient phosphate For lastingly crystal clear, clean water Mineral as well as dead organic material (detritus) may cause annoying cloudiness of the aquarium water. The latter can additionally increase the phosphate level in the water and thus support algae growth. sera phosvec･clear immediately binds the cloudiness and makes them collectable by the filter. At the same time, it removes excess phosphate and thus prevents excess algae growth. For lastingly crystal clear and clean water. Information for use https://www.sera.de/fileadmin/user_upload/manuals/sourcefiles/03390_03392_03394_03395_03396_sera_phosvec_clear_2014-05_INT.pdf

Water conditioner against parasitic crustaceans such as fish lice, anchor worms and crustaceans affecting the gills Well tolerated, highly concentrated water conditioner for the quick and complete removal of parasitic crustaceans such as fish lice (Argulus), anchor worms, crustaceans affecting the gills, parasitic isopods and small crustaceans (that may serve as intermediate hosts for other parasites) that frequently occur in ponds. Residues are broken down biologically. – A water change is not necessary. Attention: Other invertebrates such as snails, clams, crayfish and insect (larvae) do not tolerate the treatment. Amphibians and plants are not affected by the treatment.

Tropical almond leaves for natural water conditioning The sera Catappa Leaves allow conditioning the water as in natural biotopes. The tropical almond leaves support natural behavior and readiness to spawn in ornamental fish and shrimps. Furthermore they prevent bacterial and fungal infections.
