I use MB7 and Dr tims eco balance once a week, with good results.I used Microbacter clean and 7 and Dr. Tim's products. There was also a smaller label that I used but for the life of me I can't remember the name.
After I finished a bottle of each (I would rotate and dose after water changes) I found I didn't really have to add anymore. I think overall I dosed for about a year.
