After speaking with the gentlemen from Enviroswim we decided to have the ES3 system installed. Our pool is in excess of 60,000 litres. The water quality is excellent, no salt or chlorine odours. Our water is crystal clear. We have plants growing as part of the pool surrounds and unlike salt or chlorine pools any water from the pool that may fall on the plants does them good rather than harm. The service provided by Phil and his team from Enviroswim is excellent. We are pleased to be able to recommend the fresh water system.
