It's extremely difficult to reach a 0 nitrate equillibrium in FW
. As stated, the tank must be densely planted and very minimally stocked.
I agree that there are a lot of smart people out there studying and developing the products, but there are also very smart people marketing them. Words like MAY increase, CAN aid in, etc. are marketing 101 ploys that do not legally bind the company to any results. I volunteer at the GA aquarium and the lead biologist for the FW
gallery told me that he placed everything he could get his hands on onto the microscope before the exhibits were populated and the only thing that was found with ANY biological value whatsoever was biospira that was delivered cold. I'll take his word over that of anyone trying to sell their products. Caveat Emptor. I'm a bit cynical I guess though.
