Magic or openness to new opportunities for the marine aquarium?
Experiences and observations with magnetically treated water
Installation on a marine aquarium
Unlike the freshwater aquaria where, by means of water changes, it is always possible to introduce new physically treated water, the marine sector cannot be influenced the same way, since in this case mainly osmosis water is employed. However, driven by the idea that important ions and trace elements might remain for a longer time in solution after the treatment, thus becoming available to the organisms, I installed a small device of the filtering circuit of our 2.000-litre barrier aquarium. The result proved to be surprising. Several hundreds of glass anemones (Aiptasia sp.) of any size had spread all over the tank, despite many attempted interventions. Two days after the putting into service of the tool, these had all disappeared without leaving any trace. Only the skimmer signaled that there was much to be removed from the tank. However, no muddying of the water was registered. The joy of this unexpected effect was followed, around four days later, by the disappointment.
At the base of the soft corals calcareous needles had appeared which melted by the second. The actinodiscidae and several hard corals started to release from the substratum. Only the encrusting polyps did not seem to show any reaction. The device was immediately removed from the circulation of water. Losses did not occur, but the animals recovered repairing the damages after more than three weeks. The glass anemones, however, never appeared again. As a result of these observations, I can suggest an employment of such treatment as an alternative way of contrasting aiptasia; but the device should be removed immediately after the first effects on these annoying anemones.
