About to start my 180g. Curious about people's thoughts or @Aquaforest thoughts on using BioS for the 2 week startup. In a "bare" system without a source of ammonia to trigger bacterial growth and the nitrogen cycle how can it get established? I used Dr Tims before and it seems logical that some sort of ammonia source is necessary early. Why not for BioS?
Kinda related is if I should add a cycled marine pure block from my other tank during the startup phase.
I'll be setting up 5-7L of siporax in the system, skimmer and running cArbon and gfo per directions.
