Hagen Laguna I-Tronic Gebrauchsanweisung

• Where can I best place the I-Tronic?
To prevent blockage in the I-Tronic, it is advisable to place the I-Tronic after the filter, so that the water
flows first through the filter, and therefore, there cannot be any coarse pieces to cause blockage.
However, this applies only to a closed filter.
With an open filter, the I-Tronic must be placed before the filter, so that the water flows first through
the I-Tronic. The I-Tronic will then become dirty more quickly and the message 'check electrode &
water flow' will appear on the display. With the enclosed brush, the anode and cathode can then be
cleaned. Always place the I-Tronic horizontally and outside the pond, on or under the water level.
• What happens with the dead algae?
The algae come loose and float through the water. Especially with large amounts of algae, the filter
must be cleaned regularly to prevent blockage.
The dead algae that are not removed will ultimately be broken down through nitrates and phosphates
and remain in the pond environment. With sufficient plant growth, these will be taken up or eliminated
through water refreshing.
• I get the message 'check electrode & water flow.' What does this mean?
The message appears when no or not enough water flows past the copper anode and stainless steel
cathode. This can have three causes:
1. With an incorrect positioning of the I-Tronic, air bubbles can develop in the housing. The
I-Tronic should always be placed horizontally and outside the pond, on or under the water level.
2. The perforation in the cathode is silted up from dirt. With the enclosed brush, the anode and catho-
de can be cleaned to remove the green layer.
3. Air bubbles can develop in the housing if the capacity of the pond pump is insufficient. For an opti-
mal working of the models IT-05/15, the recommended pump capacity is 3,000 l/h.
• My fish swim at the surface of the pond and breathe quickly.
What is the problem?
This indicates an oxygen shortage. In this case you should install an air pump as quickly as possible,
refresh the water and clean the filter.
• The algae only disappear on one side of the pond. What should I do to get the
whole pond algae free?
Ensure there is enough water circulation in the pond, so that the copper ions can spread out over the
whole pond.
• How often should be anode be replaced?
In general, one time per season. With continuous use, persistent algae growth, and especially when
the I-Tronic is too small with respect to the pond volume, it should be replaced two or three times per
season.
• How do I change the anode?
After the pump is unplugged, you can unscrew the housing. Next, you can loosen the stainless steel
cathode and the anode can be unscrewed.
• Can the I-Tronic be used when I have snails and/or mussels in my pond?
No, the copper minerals are fatal for molluscs, even in small amounts.
• May I use the I-Tronic also in winter?
As fibrous algae do not grow during the winter season, owing to the low temperature of the water and
the limited daylight, it is not necessary to use the I-Tronic. In view of the strongly fluctuating composi-
tion of the water during the winter season and the possible consequences thereof, we even urgently
advise you not to use the I-Tronic during this period. For further information on the subject we refer to
the above instructions for use.
