Low-tech NO FERTILISERS flowering shallow Betta tank - 8 months update

As I set out in the first video, I haven't used a single drop of fertilisers, no fancy filter and no CO2 in this tank. It actually turned out even more beautiful than expected with no algae and almost no maintenance, apart from regular weekly water changes. This scape has also rewarded me with beautiful flowering of Pogostemon Erectus which has taken over the entire emersed section. By this video, I wanted to prove that a beautiful aquascape can be created without the need of additional CO2, fertilisers or fancy equipment.
