Does anyone have a sponge or any type of bacteria holding media in their sump that they would sell? I need it to establish some bacteria in my qt. I added bottle bacteria but after a week I’m seeing ammonia. My salinity may be to low as it is at 1.17. Gonna raise is slowly to 1.21. I had temp up to 80 cause I read higher temps would multiply the bacteria quicker. I have a 40 gallon breeder with 5 small fish. Purple tang. Hippo tang. Whitetail. Convict and a blotchy. No one is bigger than 2-2.5 inches. Wanna get rid of ammonia before I start adding copper. Suggestions welcomed also
