Does a carpet plant works in a walstad tank? which one should i go for?
Yeah it works perfectly. You could really do anything. The easier would be dwarf Hairgrass or dwarf Sagittaria. Monte carlo and dwarf baby tears need co2 injections. Dwarf Hairgrass and dwarf Sagittaria appreciate it but it's not needed. In a walstad id recommend a nutrient rich substrate. So yes it works perfectly fine!!
