Anyone tried or heard of one of these Best Aquarium Filter - ECO-Aqualizer A small write up from their home page In short, the ECO-Aqualizer's main function is to reduce the bonding between H2O molecules which increases interactions at the molecular level which ultimately have the following benefits to water: Separation of Oxygen atom allows for immediate oxidation of impurities Oxygen atom can and will be more easily absorbed by fishes Toxins released and become free-floating for easier & effective removal Nutrients and Trace elements can be diffused for easier selective uptake by coral Surface Tension is reduced so carbon dioxide & other gases like nitrates can escape Halogens such as Na+Cl- become freed up to naturally sterilize contaminants The result is your aquarium stays cleaner and refresher, filter efficiency increases, utilization of nutrients improves, water interaction increases (ORP), and the rate of Dissolved Oxygen increases. These all contribute to a healthier functioning aquarium. In simple terms, ECO-AqualizerTM restores and maintains water to a natural healthy balance that normally gets lost in aquarium captivity. If you understand the science of H2O molecules, you will easily grasp how the ECO-Aqualizer can achieve its full scope of benefits. But if not, it may be best to review the science of water (H2O).
