Not at all. I try very hard to be impartial in most of my threads and posts and speak about water treatment such as RO or RO/DI in general terms without mentioning specific brands or vendors. We aquarists are a pretty demanding bunch when it comes to water quality so it limits the choices to only a handful of reliable vendors and treatment technologies which leaves a great many out. Those I would consider "Reef Quality" probably number less than a dozen and the others I lump into a "Ebay" or "Drinking Water" quality. Not to say they cannot be improved upon or modified to suit our needs, but they usually end up either being a poor performer or a money trap or both. With RO and especially RO/DI you really do get what you pay for and when a good deal comes along on a Reef Quality system I try to share with others and they have done for me in the past.
