Some heavy pruning today. Pretty much anything that looked like Cabomba has been removed. plus a few other fast growers and things I didn't much like the look of. The removed plants were blocking light from the Twisted Vallis behind them which is a central plant in my overall design plan.
The things in the photo which look like scratches or white dust particles are actually tiny bubbles of CO2. The result of a bit too much CO2 entering the filter intake and getting blown out as a mist. The bubbles gather on the plants too:
