You certainly seem to be very against this company ... to be honest your comments don't seem objective.
My comments are purley based on the research I did and trust me, I did a lot. Matter of fact, I spent hours researching the product. Both here on this forum as well as others. I even spoke to the manufacturer who would disclose nothing about how it works but only about how good it works. I even spoke with others from the forum who used them and removed them.
I have had reef and salt water tanks for more than 25 years and consider myself somewhat knowledgable on marine aquariums. What I don't know, I spend a lot of time researching.
Like most people, I don't like to do maintenance so for me, that was a key factor.. Maintenance seems to be the achilles heel for most people. If they are not maintained, the bacteria will die. Dosing things like Vodka or carbon sources are a highly discussed topic in the chemestry forum and there are many pitfalls when dosing that kind of stuff. A mistake can wreak havok on a tank or worse, take out your entire tank in a real hurry.
Also they fact that they are not widely recognized when they have been around for several years is another factor which to me, said something about the viability of that product in a marine enviornment. I know they work, how well they work just isnt really proven in our applications. At least not well enough that they have garnered any kind of recognition in the marine aquarium hobby. Sulfer and coil denitrifiers on the other hand have been around for years, are used my many public aquariums and are proven to work and do it safely. They also have the upside of buffering PH and calcium if taken care of properly. There is no secret to how they work and a number of manufacturers make them.
Now that said, your comments seem very much for this solution or moreover, for the company. Being that it was your first post and you joined today, one could wonder if your motives are not about finding facts about its usefulness but more about product promotion... Not that I believe that, I'm just saying that since you pointed out my lack of objectiveness...
You asked the question and I took the time to answer and included everybit of information I know on the subject and I did it prejudice. That and I certainly didn't say anything bad about the company or the product. Just the facts as I know them and why I chose not go go that route.
