If you have a heavy bioload or high nutrients in your water. I got a few free samples at Macna of MB7 but will not be using it. Im tryingbthe bio-actif salt instead.
Under what conditions would one want/need to start dosing Mb7?
If you think your in need of a greater diversity of heterotrophic bacteria or are seeding bio pellets....it can help alleviate cyano issues by introducing competing bacteria, good luck,
