Does Microbacter 7 help with dinos? I dont have a bad case, but my sand turns brown during the day, and at night it goes away. Im also really low on nutrients, Nitrate 2, Phos 0. Ive seen Microbacter 7 come up in a lot of thread searches, but on the website for it, it says "Rapid reduction of organic carbon, ammonia, nitrite, nitrate, and phosphate." I thought the key was to raise the nitrates and phos, so how does it help? I dont want to add anything to my tank thats going to make it worse.
