Keeping and quarantine
The power of a UV-C clarifier increases with the wattage of the UV-C lamp.
With 55 Watts, the pond UVC-55X System is one of the most powerful
appliances available.
This is on the one hand due to the stronger UV-C radiation. However,
reduced intake allows letting flow a smaller amount of water per hour
through the system. The longer it stays inside the useable volume of the
pond UVC-55X, the more radiation hits every pathogen during the single
passages through the appliance. The water is subject to a higher level of
successful pathogen combat in case of a slow flow rate. The larger the
water volume to be treated, the larger the UV-C appliance must be chosen.
Of course success in combating pathogens depends on the organisms
themselves. Two bacteria species or just strains of the same species always
show different sensitivities when compared to each other. The passage
repeat cycles through the UV-C appliance depend on the size of the water
body and its flow rate. You should therefore ensure a good flow rate and
reduce non-moving zones in the water body of the pond/aquarium if you
wish to have optimally treated water.
Newly purchased fish are weakened by transport and therefore more
sensitive against parasites and pathogens. Some of the imported animals
even already carry pathogens within them, which cannot be treated
successfully more with treatments due to resistances. Using UV-C can at
least strongly reduce the spreading of such pathogens from one host to
the next. In case of quarantine use it is better to calculate generously and
choose the larger UV-C unit if in doubt. It is generally better to work in an
overdimensioned way during a quarantine.
How is a treatment carried out?
The UV-C appliance is connected to a sera Koi Professional 12000 or
24000 Pond Filter or simply to a feed pump by a hose or individual tubing.
UV-C irradiation of the pond/aquarium water should be done permanently.
Only this allows ensuring the number of pathogens remains constantly low.
With suitable dimensioning it is actually possible to reduce the remaining
pathogens to less than 1%. Many of the disease supporting bacteria have
an enormous potential to multiply and can double their numbers every 20
minutes under ideal conditions. If you, for instance, switch off your UV-C
device 12 hours per day you may under certain circumstances experience a
sudden massive multiplication of bacteria: after 36 cleavages (3 cleavages
per hour) one single bacteria under optimal conditions forms 68,72 billions.
However, bacteria cannot be diminished that quickly the other way round.
How and on what does UV-C radiation have an influence?
Every living animal is exposed to numerous threats by pathogens and
parasites. In case of keeping the animals in a pond or an aquarium less
than optimally, pathogens can exceed the natural organism density and
weaken the animals by infections.
Using UV-C does not lead to water sterility in aquatic systems, and therefore
also not to "increased sensitivity of the animals towards diseases due to
lacking immune system burdening", but reduces pathogen pressure and,
accordingly, stress. The pathogen pressure reduced by up to 99% therefore
has positive effects on the health of the animals. Parasites, fungi and algae
in the water are also minimized in a way analog to the bacteria.
Bacteria
Depending on the present conditions, there are different bacteria species
in the water. This also includes some that may be dangerous for the fish
and other inhabitants in larger numbers, as well as some that are called
"filter bacteria" (genera Nitrosomonas and Nitrobacter ), and which are
responsible for the breakdown of pollutants during filtration. Bacteria can
dwell freely in the water or be substrate bound. The filter bacteria are mainly
substrate bound and therefore do not get into the UV-C unit. Using a UV-C
unit therefore does not affect pollutant breakdown in the aquarium. Being
free water inhabitants, disease causing pathogens, however, are drawn into
the UV-C unit and irradiated. Even short contact with the radiation leads
to massive metabolism problems in the bacteria so they subsequently die.
Viruses
The metabolism of virus works differently than that of bacteria, but the
spreading of viruses through the water can also be controlled by UV-C
radiation. It also applies here – the less viruses can reach other fish, the
lower the risk of an infection.
Single celled parasites
Protozoans such as Ichthyophthirius, Trichodina, Piscinoodinium are
responsible for various widespread diseases. White spot disease is known
best. In this case, UV-C can be very helpful since the spreading stages of
all protozoans are considerably reduced.
Higher parasites
Fish parasites (e.g. anchor worms Lernaea sp., fish lice Ergasilus sp.,
flatworms Plathelminthes , nematodes Nemathelmintes ) are often
permanently on their host and usually are not irradiated by UV-C light,
but their larvae searching the water for new hosts are. The spreading of
larvae and their settling success is therefore considerably reduced by UV-C.
Fungi
Fungi and their spores are almost ubiquitous, also in the water. They
cause so-called mycoses and can rapidly spread in living fish tissues.
This leads to large-area infections of mucous membranes. The tissues
swell, and spore carrying fruiting bodies reminding of mold form within a
short time. These fungus spores grow into fungal hyphae and can infect
other weakened or even healthy animals. Carriers of fungal infections
usually also become victims of bacterial infections, this is thus called a
multiple infection or superinfection. Directing water through a UV-C unit
also successfully reduces fungus spores during the passage through the
pond UVC-55X System.
Algae
Single celled algae can rapidly multiply by cleavage due to unfavorable
nutrient levels and strong sunlight, and actually turn the water green. The
oxygen consumption of algae during the night can quickly become so high
that oxygen depletion and respiratory problems of the fish may occur.
With few exceptions, the single algae cells are so small, that they are not
separately visible to the naked eye. They are being drawn through the
UV-C unit just like spreading stages of substrate bound algae. The UV-C
radiation destroys the algae and their reproduction stages. The water
becomes clear again.
Basic rule: the slower the water passes through the sera pond UVC-
55X, the longer the UV-C exposition time of the water to be treated.
This leads to a higher degree of purity.
