Well, sounds like DocTim's been working on his contract agreements! Its funny to see the marketing types get going with a new product. Even with somebody as good as Tim I wouldn't put fish in there that fast but it will definately be interesting to see if his concoction can perhaps act somewhat like mature media. The test, as always, will be in whether 5ppm of ammonia could be dropped to zero ammonia and nitrite within 12 hours after a filter has been seeded with the product.
Technically, the thing of course that makes one skeptical is that its not just the "presence" of Nitrosomonas and Nitrospira in these biofilters, its the establishment of healthy biofilms in which the bacteria can mature and reproduce and be anchored in a tough manner. As a scientist with plenty of bacteriology background, you can bet that Hovanec himself knows this, that there's got to be lag phase activity prior to growth phase quality.
