General maintenance update

I have lately moved to the reduced water change way of doing things, gradually reducing water changes over the last couple of months. This is working well, the with Amazon sword showing improved growth, although the rest of the plants suffered until I increased the lighting and finally switched to a “siesta regime”, which is 5 hours on, 4 hours off, 5 hours on, off for the night arrangement. This new regime seems to have helped reduce the hair algae.Since I removed the duckweed (Lemna minor), which was not a great idea, the Limnobium laevigatum (Amazon frogbit) had been flourishing alongside the Riccia fluitans.
