Upon hearing about the ClearBlue Ionizer from one of the local retailers in Ottawa, Canada while searching for a system for our new pool in Costa Rica I was immediately interested. Since it’s installation, which is quite easy for your regular handy man or your pool maintenance person (can be installed in less than an hour) my family and friends have enjoyed clean and near chlorine free swimming on a daily basis. The pool maintenance people who come weekly have been enjoying cleaning my pool which is essentially sparkling when they come. We live in the jungle so there is constantly leaves from the trees falling into the pool - so removing the leaves and cleaning the filter weekly is essentially all that is done. During the rainy season the ionizer level is increased a little to manage the influx of new rain water that is received from the torrential rainfalls. The pool maintenance people are in awe in the fact that they barely add any chlorine to the pool as compared to the pools they maintain that do not use the ClearBlue Ionizer system. I recommend this system to everyone when we talk about our pools... oh and the big bonus so my fiancée keeps mentioning us that her skin feels soft and does not smell chlorinated. Pura Vida.
