My bacteria blooms always cleared naturally (Only had a few, though one was quite intense) and don't use driftwood but having a lot of dealings w/ fungus in general, as soon as the foods gone it's gone.
That, depending on the wood content, could be fast or long.
I'm no expert in cycling so I'll defer on that question. Most of my cycling is done w/ seeded media Seachem Prime , some livestock and nature.
Never takes very long that way.
As long as you just have plants in there and monitoring ammonia/Nitrite/Nitrate why add stuff??
Used pure ammonia right? not the stuff w/ surfectants/perfumes..
AFAICT fishless cycling doesn't usually include plants. ammonia can burn plants.
Current death/decay rate is probably enough to jump start the cycle now.. as is..
A resource.. One of dozens..
Kind of like this one. The idea of the disc (used them in the past) saves dipping tubes and testing or expensive strips.
BTW: What is your current pH.
