Eaglesaquarium, thanks for the link to the post by DocTim. I had no seen that before. His statement about the preferred concentration to encourage the right bacteria goes much further than WD and I have been going. The .14mg/l concentration is less than 1 ppm of nitrites. I will try to keep that in mind when I am giving advice since DocTim is the authority on what conditions the various bacteria need for proper growth.
No problem, it was my pleasure. TwoTankAmin mentioned that he had been on several forums previously answering questions about his product (One and Only) and I figured I'd do a google search. I didn't expect it to bring me back to this forum.
