JBL Pro Clean BAC Cleaning bacteria that instantly clean your aquarium. A cartridge filled with cleaning bacteria that will keep your aquarium clean and your fish healthy. These bacteria are among one of the good bacteria that transform toxins into harmless ones. Various JBL bacteria products contain high concentrations of certain strains of bacteria that, for example, convert problematic nitrogen compounds such as ammonium (NH4), ammonia (NH3) and nitrite into harmless nitrogen compounds (nitrate (NO3) or nitrogen gas (N2)). You also don't need to worry about overdosing the Pro Clean BAC because the bacteria will extract your nutrients from these nitrogen compounds and if they don't eat enough, these bacteria will die. Helps keep the aquarium cleanBefore use, shake the cartridge and empty the entire contents into the aquariumSupports the filter, breaks down pollutants and cleans the bottomBest used after a water change, adding a new fish or cleaning the filter

PROCRISTAL UV-CCrystal clear and healthy waterPoor lighting conditions, over-fertilization or even an excess of nutrients can have a negative effect on aquarium water and promote algae. Suspended algae lead to green turbidity, bacteria to whitish turbidity. The JBL Water Clarifier removes turbidity caused by bacteria and suspended algae. The aquarium water is passed through the stable, UV-resistant housing of the clarifier. The UV-C radiation kills the bacteria, other germs and suspended algae in the water flowing through. The efficiency of this UV-C water clarifier is particularly high because the glass bulb is surrounded by a polished, reflective stainless steel foil that reflects the UV-C radiation, thus doubling the efficiency. This can also have a positive effect on the elimination of sessile algae, such as filamentous algae, as their spores are also largely killed.No harmful side effectsNo change in water values / no negative effects on important cleaning bacteria in the filter.Easy installationConnect the water clarifier to the external filter or a separate water pump. Due to included 90° angle, any desired installation position can be achieved.SafetyThe JBL UV-C water clarifier is TÜV-tested and has a safety switch for automatic shutdown when the device is opened. The housing is UV-resistant and sturdy walls and has an LED lamp that indicates whether the UV-C burner is working .Difference from the previous model JBL ProCristal UV-C Compact:The function indicator lights are now located on the flat side of the electrical unit and the microswitch for automatic shutdown of the burner when the housing is opened (if the plug has not been pulled out) is changed to a magnetic safety switch. As a result, the electrical units of the previous models (Compact) do NOT fit the new ones (Compact Plus) and vice versa. Crystal clear and healthy water: 36 W UV-C water clarifier for fast and efficient removal of greenish and whitish turbidity in freshwater and saltwater aquariums as well as garden ponds.Space-saving installation: connection to external filter or separate pump.

Convenient and effective way to catch flatworms (planaria) without using chemicals Equip trap with food bait (JBL NovoTab), use suction pad and cord to hang it at an angle over the bottom and empty trap the following day Convenient emptying of the trap: open lower plug and upper screw top and rinse under running water Completely non-toxic in freshwater and marine water Ø 17 mm, 13 cm Package content: 1 complete planaria trap (13 cm long) with transparent cord and suction pad for slanted positioning Flatworms (Platyhelminthes):To this class of animals belong the unpopular planaria which sometimes massively reproduce in aquariums and then can become a disturbing pest. They mostly lead a hidden existence and appear only at night. After using a planaria trap many people are surprised how many flatworms were present in their aquariums! Since chemical means against planaria have mostly unwanted side effects, the JBL planaria trap is a very good alternative without harmful side effects!Flatworms in marine water:Flatworms in marine water can look very beautiful, such as slugs. But they can also cause problems for corals, when they increase alarmingly and infest the corals. There are Turbellaria which, extremely well camouflaged, even can’t be found on a closer look. This also includes e.g. the Acropora-eating flatworm which can infest stony corals and lead to serious damage. Through an iodine bath of the affected coral outside the aquarium (2 ml Betaisodona/l) the Turbellaria will be paralysed and can be flushed away with a strong water jet. The wrasse Pseudocheilinus hexataenia is considered as the recommended natural enemy of choice, as it can even recognise clutches of worms to eat them.

EHEIM Multibox 31 x 18.7 cm H 10 cm The EHEIM MultiBox is a clever and extremely practical idea for both aquarium maintenance and aquascaping, keeping everything you need at your fingertips.  Just hang it on! The simplest ideas are often the best. Where would you normally put your tools such as scissors, tweezers, glass scraper, plant tongs, etc., whilst doing maintenance work on your aquarium? Where do you put your plants and utensils for aquascaping? What do you do with dripping internal filters, plant residue and waste? Where do your new aquarium inhabitants get used to their new environment? Where is your quarantine or treatment area? The EHEIM MultiBox is the perfect solution for organising your work area – simply hang it on the aquarium glass or cabinet door. The hanging bracket, tool holder, lid and overall dimensions have all been skilfully designed for convenience and practicality. Multifunctional: Practical, hook on container for maintenance work and aquascaping Section for plant residue, algae and other waste Can be used for carrying wet items (internal filters) to the sink or waste to the bin Compartment for acclimatising tank inhabitants to a different or new environment Quarantine or treatment compartment Divided lids prevent fish from jumping out (opening for ventilation hose included) Secure fit: Simply hang on the aquarium or, if the aquarium hood makes this impossible, on the cabinet door Hanging bracket can be adjusted from 4mm (for aquarium glass) to 20mm (for cabinet doors). Spacer for vertical adjustment – locked in position at the bottom of the box 6 eyelets to hang on tools (tweezers, scissors, fish net, glass scraper etc.). Ideal dimensions: Dimensions (L x W x H): 310 x 187 x 101 mm. The box can be filled with up to 2.5 l of water. The size of the box is ideal for acclimatising fish to their new environment as, once settled, they can be gently caught and released into the aquarium with a small net. This reduces the risk of infection, as no external water is introduced into the aquarium.
