We have had our Floatron for approximately 4 years. We live in SW France and have used it in a mediaeval ‘pond’ which is stone lined and which is filled by water draining off the hill above. It measures 2.5 metres x 4 metres and is roughly 1.5 metres deep, obviously less in the heat of the summer.
The wild life has introduced itself, mainly frogs and salamanders. I was concerned about the water quality but since using the Floatron we have never had any trouble except when I forgot to clean the electrode, then as soon as it had been cleaned, the water cleared.
The frogs use the floatron as a sun-bathing platform!
