Iron is of crucial importance for all aquarium plants. It is needed for generating the all-important chlorophyll. Without chlorophyll the plant cannot photosynthesize The effects of iron deficiency are immediately apparent the young leaves appear pale & yellowish (iron-induced chlorosis). Please note plants can only absorb divalent ´white´ iron. This is unfortunately not stable in an aquarium & is quickly oxidized to become effectless trivalent ´brown´ iron. Tap water contains virtually no iron. Aquarium plants are therefore reliant upon regular iron fertilization. E15 Fer Activ iron fertilizer provides all aquarium plants with divalent nutrient iron that they can use immediately thereby ensuring a beautiful fresh green color. Symptoms of deficiency such as yellow glassy leaves are thereby virtually completely cured while young leaves can once again display a rich green color. ...

FB1 Substrate Start is a highly-active mixture of selected bed bacteria. All you need to do is spread it onto the layer of Deponit Mix & cover it over with aquarium gravel. FB1 bacteria are activated immediately upon coming into contact with water thus transforming the bed of the aquarium into an active bio-filter. Living humus bacteria pre-digest nutrients to convert them into a form that plants can use. For a quick reliable start. ...

DENNERLE FB7 Bi Active is a highly active concentrated mixture of selected living cleaning bacteria. They start to work degrading harmful substances immediately on entering the aquarium water. Efficient nitrifying bacteria remove dangerous ammonia & nitrin. Sludge-degrading bacteria reduce the organic sludge on the aquarium bed & in the filter with the aid of hydrolytic enzymes. Other types of bacteria bred specifically for aquaria feed on plant & food residues fish excrement & organic suspended matter. FB7 Bi Active boosts the self-cleaning capacities of all fresh water aquaria on a lasting basis. The optimized water conditions reduce stress. The fishes´ well-being is enhanced in a healthy environment. The water remains clearer. Breaks down fish excrement dead plant matter & food residues even in inaccessible areas Activates the aquarium´s biological self-cleaning capacity Removes toxic substances such as ammonia & nitrite Activates aquarium filters improves filter performance With bioactive sludge-degrading bacteria Bacteria play a decisive role in maintaining the biological balance in an aquarium. These invisible helpers continually remove fish excrement dead plant matter & food residues. Each type of bacteria is specialized in certain substances. This means that only the ´right´ bacteria guarantee swift & reliable degradation of the waste substances which typically occur in aquaria. A new aquarium or fresh filter material are virtually sterile. Without active assistance it may take many weeks for a stable bacterial fauna to develop. Substances which are toxic to fish such as ammonia & nitrate may accumulate & pose a danger to life in the aquarium. Only an extremely minimal level of bacteria is permissible in tap water for human consumption – which is why it is chlorinated by the waterworks. Aquarium fish need water which is ´alive´ however. ...

Shrimps are normally omnivores with an emphasis on plant-based food. Their natural diet contains next to algae animal plankton detritus (fragments of dead plant organisms) & even carrion. In the aquarium most of these natural sources of food tend to be absent or insufficiently provided. A high-quality shrimp food can supply a basic nutrition. This should be supplemented with a regular supply of frozen or live food (mosquito larvae artemia) Dennerle algae food fresh vegetables such as spinach & courgettes Dennerle Catappa Leaves or herbs (nettle) to ensure variety. Natural food supplement for shrimps. At a glance 100% natural algae (Nori) Rich in vitamins & trace elements Boost the animals´ natural colours ...

The Dennerle Nano Cool Air eco reduces the water temperature of your aquarium by 2 to 5 °C. This water cooler uses the principle of "evaporative cooling", which arises when air moves over a moist surface. The cooler attaches to the outside of the aquarium & turns on only when it is needed, which makes it energy efficient & safe to use. The water temperature of an aquarium is one of the most important factors in maintaining a suitable environment for your fish. The Dennerle Nano Cool Air eco helps control the temperature of the water effectively, preventing it from getting too warm for your fish. The cooler operates on 12V & attaches to the outside of the aquarium, making it safe & easy to use. It constantly measures the temperature of the water & will automatically turn on once the water reaches a pre-set maximum temperature. Using the evaporation principle, air is blown directly over the surface of the water, helping it cool. The temperature of the water can be reduced by 2 to 5 °C, depending on the size of the aquarium & is suitable for aquariums between 10
- 100 litres. The Dennerle Nano Cool Air eco only switches on when it is needed & will automatically turn off once the water temperature is cool enough. This not only helps save electricity but also prevents the unnecessary evaporation of water from your aquarium. The aquarium cooler has two adjustable power levels, full & half power, giving you more control over the water temperature. Dennerle Nano Cool Air eco at a glance: Electronic aquarium cooler for marine & freshwater aquariums (10
