This is the communication I had with seachem...
|Message: I use nearly all of your products, but I have a question. You say that as long as nitrate stays controlled that denitrate is not exhausted, but denitrate uses biological nitrate removal primarily- therefore, how does the bacteria- "exhaust?" I understand that the denitrate can get impacted with dirt, so I use filter floss prior to the denitrate in an aquatop media reactor. I am not sure if this is how it could "exhaust." Also, does stability contain denitrifying bacteria that can seed the denitrate? Thanks!|
Thank you for your email. What we mean by "exhaust" in this context is "run out of room to grow". You are correct that, given infinite resources, bacteria colonies will continually multiply and remove nitrate, but it is entirely possible for the bacteria colonies to exhaust their available resources (space, nutrients, etc.) and stop growing. If nitrate remains under control, the bacteria colonies still have plenty of space (deNitrate), nutrients (phosphate, carbon, and trace elements in addition to nitrate), and proper water conditions (water flow, pH and temperature stable). If nitrate starts to rise, then the bacteria colonies lack one of these resources, and the most likely one is space.
Stability does contain denitrifying bacteria to seed the deNitrate, so you can certainly use it in conjunction with deNitrate if you wish.
