I knew the black spots were the bad stuff. Lol now i know exactly what it is. Thanks. And the microfauna can and should disapate any bad areas. Asuming the bed is healthy.Correct?
Any trapped gas you can see is not toxic. It is either nitrogen (most likely) or just air.
Hydrogen sulfide that may be produced if a lot of organic matter gets buried is not going to be present in the gas phase, but will show as black precipitated metal sulfides.
I used a bag of fresh live sand, an inch layer on top of my old fuge sand which had a slightly bigger grain size and was full of critters, some bristle worms from a forum member and two orders of pods from different vendors. As well as multiple macros from various venders which I'm sure brought stuff in. So far I've recorded over 9 types of worms and 10+ types of "bugs" as well as mini chitons, snails, limpets, micro britles etc... defanitly full of life. Although I'm always looking for more ways to seed it. So if you know any, don't be shy
