Trying Polyp Lab's "System Reef-resh" this weekend.

The factual information in your quote from Bomber is correct. (That sounds like something that he would say but I could be wrong)

But while excess nutrients are "sitting in solution" they are also being grabbed by organisms that you do not want growing (like nuisance algae).

I completely understand the skepticism. It is very difficult to look at a product like this and give it the benefit of the doubt.
