I have finally convinced my wife that we need an RO unit, not for the reef tank, but for better tasting water. My question is, are the models that come from Lowes or Home Depot just as good as the models from Kent or similar companies? I checked out my local Lowes and the models they had did not mention the removal of phosphate, nitrates, etc. I was thinking that maybe they aren't listed because they are not important to the average consumer. Any thoughts?
