Eco Aqualizer

The device as advertized is not a replacement for good house keeping and is not intended to replace neccessary equipment. it is to enhance the capability of the system to cleanse itself and to promote oxygen levels which tend to act as an oxydizer. There are not miricles out there. if your system is not adequately set up, this device will not replace missing equipment. I will be using one on my system to see just what it will do, but, i am at least a year away from having any meaningful results or may 2 years. hope this helps and just my two cents worth. There are others that are fanatically on both sides of the coin. some for and some against. I felt it was worth a look based on a positive review by one of the german authors. this is not new technology but 1st time marketed for the aquarium industry. hope this also helps.
