CO2 addition device for freshwater aquaria
UNIVERSALLY APPLICABLE. DENNERLE CO2 addition units can be combined with all DENNERLE CO2 fertilization systems. They are also ideal for retrofitting or increasing the performance of existing CO2 systems. False gas venting: Whenever a CO2 bubble dissolves in the water, other gases naturally dissolved in the aquarium water (e.g. nitrogen) simultaneously enter this CO2 bubble. All DENNERLE CO2 addition units therefore have a specially developed false gas vent. Here, the false gases are separated from the – significantly heavier – CO2 and are automatically discharged at regular intervals. Possible “clogging” of the units by false gases is effectively prevented. DENNERLE CO2 addition units are therefore highly effective. The valuable CO2 is used in the best possible way.

For highly effective CO2 dissolution through nano atomization
Controlled supply through integrated bubble counter
Also suitable for Bio CO2 systems
Made of high-quality, transparent acrylic
Ultra-compact form – can be installed “invisibly” in the aquarium
With suction holder
For hoses 4/6 mm
Mount vertically in the aquarium for a few hours before use so that the diffuser fills with a little water.Dennerle offers a series of ultra-modern CO2 addition units under the name “CO2 Diffusor Ultra”. The diffusers are made of transparent, break-proof acrylic. This makes them considerably safer to handle than conventional glass diffusers and also ideal for children’s aquariums, for example. Due to their ultra-compact shape, they can be installed “invisibly” in the aquarium using the suction holder provided. Thanks to their attractive appearance, however, they are not disturbing in the visible area either. The newly developed membranes are manufactured from a special sintered material with extremely small pores. The resulting nano-atomization of the supplied CO2 ensures a highly effective and safe dissolution of this important plant nutrient in the aquarium. With the help of the integrated bubble counter, the amount of CO2 added can be easily checked at any time.The CO2 Diffusers Ultra can be combined with all common CO2 systems, e.g. the Dennerle disposable and reusable systems Carbo START, Carbo POWER and Carbo NIGHT. Due to the much lower operating pressure of approx. 0.3-0.5 bar compared to classic glass diffusers, the CO2 Diffusers Ultra are also ideally suited for bio CO2 systems. The hose connection fits all commercially available CO2 hoses with 4/6 mm, e.g. the Dennerle special CO2 hose. The CO2 Diffuser Ultra S is suitable for aquariums up to 100 L and therefore very popular especially for nano aquariums. The model M supplies aquariums up to 200 L, the model L aquariums up to 400 L

Activated carbon is a form of carbon that has been treated with oxygen to make it very porous, allowing for a larger surface area for chemical reactions to occur. The carbon absorbs organic materials and Chlorine from the water it comes into contact with. The Activated Carbon Block is enclosed in a 5-micron filter to catch tiny carbon dust particles that may break off during the filtration.

AQUAEL UNIFILTER is designed for the cleaning and aeration of aquarium water. The horizontal rotor chamber facilitates cleaning without the need to disassemble the filter. Since the filter can operate in the horizontal position, it is ideally suited for aquaterrariums and terrariums where turtles are kept. AQUAEL UNIFILTER is easy to operate; its performance can be controlled using the dial formed by the rotor dome. The direction of water outflow can be adjusted by up to 90°
The larger models, UNIFILTER 500, 750 and 1000, are equipped with a ceramic rotor axis for even quieter operation and enhanced durability.The specially designed filter media chamber prevents water from flowing out of the filter and into the fish tank during water changes or when the filter is removed from the aquarium e.g. in order to change the water or wash the sponge.
To facilitate the maintenance of AQUAEL UNIFILTER, we provide two separate sponge cartridges, which can be separately removed and cleaned in turns. In this way, colonies of nitrifying bacteria, essential for nitrogen processes, are protected. In order to provide uninterrupted filtration, it is recommended that sponge filter cartridges should be cleaned in turns and independently of each other.The filter can be hung on an aquarium wall in two ways: either the shorter or the longer side up, so it can be easily concealed behind decorations or plants

The LEDDY TUBE modules employ advanced LED technology. As a result, they emit the same amount of light as regular fluorescent lamps while consuming half the energy, which is important for environmentally conscious consumers and translates into considerable savings on electricity bills.An additional advantage of LED modules is their durability. Unlike the regular fluorescent lamps, whose light output drops by half after one year of use, LEDs can be used for many years without replacement, thereby saving even more money.
The LEDDY TUBE modules are very easy to install. Each model is supplied with special adapters so that they can be assembled into any luminaire. The modules draw power from an independent supply source.
Four versions of the product are available: two for freshwater aquariums (LEDDY SUNNY, which emits light with a colour temperature of 6500 K similar to natural sunlight, and LEDDY PLANT with a colour temperature of 8000 K, designed to enhance the growth of aquatic plants) and two for marine aquariums (LEDDY MARINE, which emits light with a colour temperature of 10000 K, designed to improve corals growth and LEDDY ACTINIC – 20000 K - for better colours of corals).

A quality planted aquarium substrate provides the foundation for healthy plant growth.
Ultum Nature Systems Controsoil is a natural blend of soil and volcanic ash. Setting it apart from other substrates, Controsoil does not contain high nutrient levels that can cause spikes in ammonia levels. It primarily focuses on impurity absorption and providing balance from the start. This approach makes UNS Controsoil a great choice for all skill levels and allows anyone to create a beautiful aquarium.
Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice.
No Rinsing Required
Inhibits cloudy water by actively absorbing impurities
Low Ammonia Release
Promotes and accelerates beneficial bacteria growth
PH & KH buffering
Buffers water to slightly acidic pH and lowers total water hardness for better aquatic plant nutrient consumption environment
Optimal For Fish And Shrimp
Suitable for all fresh water inhabitants such as tropical fish and shrimp that prefer slightly acidic aquarium water
Designed For Planted Aquariums
Granule composition and sizes provide optimal oxygen exchange for aquatic plants
Ultum Nature Systems Controsoil along with a competing freshwater planted aquarium soil were scientifically tested in a controlled environment. The test was performed by a published, independent third party and consisted of an experiment using both soils side by side for a 2 week duration. RODI water was used and water changes were not performed for the entire duration to ensure continuity and to prevent data inaccuracy that would adversely affect final results.
The below findings indicate that Ultum Nature Systems Controsoil is an ideal choice for all freshwater planted aquariums.
TDS
Measures the levels of combined organic and inorganic substances found in aquarium water other than pure H2O molecules. These solids consist primarily of minerals, salts and organic matter. This measurement can be used to determine the water source’s general quality and purity. Weekly water changes are encouraged to decrease TDS.
AMMONIA (NH3) AND NITRATE (NO3)
Ammonia provides a jumpstart in a newly set up aquarium quickly without the use of third party chemicals and/or additional product(s). As ammonia decreases, nitrate levels increase. Once this step begins, livestock additions may be considered. This process is often referred to as “cycling a tank”. UNS Controsoil begins this process by immediately releasing minimal amounts of ammonia into the water column. Based on controlled tests performed, an aquarium may be cycled in less than 2 weeks time when using Controsoil.
During the 2 week test period, ammonia levels spiked following the 6th day. This was due to the absence of water changes. Weekly water changes are always highly recommended to prevent ammonia spikes. A spike can be potentially lethal to all aquarium livestock.
PH
A measure of acidity and alkalinity. Controsoil successfully stabilizes pH levels to 6.8pH over time. This pH level is ideal for all tropical livestock, freshwater shrimp and aquatic plants. It is important to note that stable pH environments positively affect the longevity of a planted aquarium and its livestock.
