|
 | Mineral as well as dead organic material may lead to cloudiness. The latter may additionally raise the phosphate level in water and thus support algae growth. sera phosvec-clear immediately binds the cloudiness and makes it collectable for the filter.
| |
|
 | sera KH/pH-plus precisely and lastingly raises the KH to the desired value. The pH value is gently raised as well and, above all, safely stabilized. The carbonate hardness (KH) is one of the most important water parameters in an aquarium.
| |
|
 | 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.

|
 | sera toxivec contains the innovative QuickClean Formula and immediately removes dangerous pollutants threatening fish and filter bacteria from the aquarium water. The parallel efficacy against different kinds of pollutants makes it especially valuable. The quick effect of sera toxivec removes ammonium and nitrite in no time.
| sera toxivec immediately removes dangerous pollutants | from 3.79 €* |
|
|
 | sera mineral salt for the increasing of water hardness in osmose water, pouring, and soft water. 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.

|
 | sera O2 plus - simply sprinkled into the aquarium water - immediately adds oxygen and thus improves the living conditions for all aquarium inhabitants. The breath of the aquarium inhabitants as well as other natural breakdown processes constantly consume oxygen. Certain circumstances may lead to acute deficiencies.
| sera O2 plus emergency support in case of oxygen deficiency | 7.85 €* |
|
|
 | sera GH/KH-plus simultaneously increases the carbonate and total hardness in the warm water aquarium. This way osmosis water or soft tap water can be specifically hardened or the natural consumption of the hardening agents can be balanced. In addition, the values for the care of hardness loving fish species can be adjusted.
| sera GH/KH-plus increases simultenously GH and KH for osmosis & tap water easy and safe to use | from 6.85 €* |

|
 | The sera alder cones prevent fungal infections and spawn fungus in a natural way. Additionally, they support natural behavior and readiness to spawn, and they lower the pH value of the water. Alder cones are suitable for preparing black water, which ideally recreates the natural living conditions and thus allows for appropriate care.
| |
|
 | 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.

|
 | Sera filter biostart is a high-performance product made from enzymes and microorganisms for speeding the biological breakdown of polluants (such as ammonium/ammonia) in freshwater aquariums. Sera filter biostart provides a reduction of organic matter, such as fish excrement and food leftovers. It also prevents the formation of unpleasant odors and promotes the biologicalequilibrium.

|
 | sera marin bio reefclear, a sera biotechnology product for saltwater aquariums, breaks down ammonium and nitrite due to the purification bacteria it contains. The included mineralic volcanic rock removes pollutants, effectively binds turbidities and provides settling space for the purification bacteria. For healthy, clear and biologically active water.

|
 | sera marin component 3 trace elements Anionics provides important trace elements as required daily. In combination with sera marin component 4 it optimizes the supply of corals and other invertebrates with trace elements.
| |
|
 | sera marin component 6 magnesium contains important Magnesium. Magnesium and Calcium must be present in a balanced ratio for the optimal growth of corals and other invertebrates. The Magnesium level should not be below 1,300 mg/l (ppm).
