This is definitely a huge myth and unfortunately a frequent misunderstanding. It's too bad that so many people who go around masquerading as experts insist upon propagating it. It is true that plants, corals and other animals require trace elements to survive however the key word is TRACE. EXTREMELY small quantities are necessary. In FW planted systems all of the trace elements ever needed are typically provided in any good fertilizer supplement and even that isn't needed much if you have really good soil in place. For the fish themselves, any good food will provide any trace elements needed.
In saltwater systems there are many different kinds of supplements on the market which all do a great job of keeping trace elements plentiful for coral and live rock. I personally like the two part system such as B-ionic. Again, for the fish themselves, any good food will provide any trace elements needed. If you eat a healthy and balanced diet, do you need trace elements in your water??? The answer is no despite what the makers of Gatorade would have you believe.
The Aquaripure does not remove ANY trace elements from the tank. I definitely advocate doing a water change every few months for the express purpose of keeping trace elements in balance. If nitrates are not a problem this is more than enough in any tank to keep trace elements in balance. In a planted tank or reef tank you would want to use supplements just as any other person would.
One thing is certain ... a person can very safely be dramatically cut back on water changes when nitrates are removed ... and water quality will still be far superior to what it was before. Again, individual experiences will vary but this is fairly typical. Some customers may need to change water more often than others.

Thank you for such an informative post, but can I ask if there is a data sheet available with long term testing results listed? As much as your concept sounds good, its still kind of hard to just take someone's word for it, especially considering the cost in an initial purchase for such a product.
I know that when relying on denitrifying bacteria to work naturally in saltwater certain water conditions/params must be met to support the bacteria growth... does your product require anything specific to keep the bacteria growing and at a plentiful enough rate to keep working?
One other point I'd like to make and then I'll shut up about it for a while <wink>. In that link you sent me to, I read the entire thing, and it states in there to do a water change to relieve phosphate levels... shouldn't you be pointing out that someone first needs to test their source water for phosphates before considering the idea that a water change will relieve these levels? I'm not sure where you're from, but around here the tap water used in most fresh water tanks is full of phosphates, among other things.
Please don't view me as attacking you, your product, or your concept... that is not what I'm trying to do. I am simply running you through the same routine I do with any company rep comes to me and asks me to promote or sell their product... I tell them all the same thing... "you have the same chance as anyone else, so convince me..." I ask a lot of questions because there are a lot of products out there claiming to do something, when in fact they can cause more harm than good. Tetra has a product out called Easy Balance, also said to relieve the need for water changes. Their product, however, simply binds waste levels... it doesn't remove it, break it down, etc. My arguements with the reps at that company were endless, finally ending with my statement, "when you can prove a product that means I no longer have to flush my toilet, then we'll talk again". Unfortunately, the owner stocked that product, and against our advice in the fish room, many used it and did as the bottle directed. Those same people came back weeks and months later with such huge issues caused by lack of water changes that even though the owner put it on our shelves, the entire staff discouraged people from using it. I am skeptical of anything that claims to do such wonders... so for you I guess I'm simply saying the same thing I tell the others... it sounds great, now convince me!
