Very good links and I am an avid reader. However I've got bacteria that are diminishing as we speak so I came to this forum for the short version.
That said, I've done everything I could to save this media. I've filled the sump with the proper salt water, I've cycled the media using an extra Fluval 405 I had, I added and airstone and I've made an initial ammonia chloride feeding (I'll keep on feeding daily).
If this mediai stays alive, I'll immediately set up a large container to start cycling my rock using this media as a base.
