Unsure about Substrate under cap!
I'm a bit confused as to what substrate I should use under the cap.
The cap for the substrate would be ada amazonia regular or powder so the finer roots can get established. This amazonia is very difficult to find...
Underneath the amazonia I was hoping for a cheap but beneficial alternative, since the ada is too expensive for me to fill an entire tank with.
1. MGOCPM, but I'm afraid about the tannins/kicking up dust.
2. Inert sand with root tabs
3. Your recommendation!
