The first pic looked like you used yard dirt. If that is correct, it was probably okay. The new substrate is dangerous and needs to be removed ASAP. Soil, sand or shavings should never be used with tortoises. Orchid bark is best.Substrate is mix of sand and top soil that first pic was last week I’ve since done research and changed a lot but still need as much help and input many thanks
Nice job!And top soil
