Velda T-Flow 05 Mode D'emploi page 22

SUMMARY
l Carefully read the instructions and visit www.velda.com for further information.
l Measure the pH, GH, and KH values of the pond water and adjust them if necessary.
l Always place the T-Flow Tronic horizontally and outside the pond, on or under
the water level.
l Always start with 5% activattion and if necessary, increase weekly by 5%.
l Perform regular maintenance on the T-Flow Tronic, so that it works optimally.
l At water temperatures below 12°C the system will shut down automatically.
Remove the T-Flow from the pond and store it in a dry and frost-free place.
WARNING FOR SIDE EFFECTS
You should realize that, by removing fibrous algae, you influence the balance of
the pond environment and thus the composition of the water. This may occur not
only when using algae killers, but also when removing algae by hand. The fact that
an important oxygen source is gone, can make extra aeration necessary to ensure
a sufficient oxygen supply for the fish. Although problems will seldom occur, risks,
including death of fish, can never be entirely excluded. This also applies to the use
of the T-Flow Tronic. If the T-Flow is applied in the way described in the present
user instructions, problems will almost certainly not occur. However, as the envi-
ronment and composition of pond water will differ from pond to pond, Velda can
not exclude death of fish for 100%, also in case the T-Flow Tronic is used.
After activating the system, the fish may exhibit a shock reaction lasting a few days.
This has no side-effect and after a short time, normal behavior is restored. If fish
should go on behaving in a deviant way, we recommend to leave the T-Flow switched
off for a couple of days. The T-Flow Tronic can be switched off manually by lowering
the rate to 0% (Off ). It is a generally known fact that copper (Cu) ions with a
concentration of 0.2 to 0.3 ppm (0.2 to 0.3 mg per litre water) hinder algae growth.
According to the European drinking water standards, even a Cu ion concentration of
2 ppm presents no danger for people and animals, with the exception of inverte-
brates such as snails and mussels. The T-Flow has been constructed so, that normal
pond water, having a pH value 7 or higher, can not contain too high concentrations
of Cu ions. However, because Velda has no supervision over individual use of this
apparatus and has no input regarding the environmental circumstances of the
pond, Velda bears no responsibility for possible failures or damage.
