Great video! Your plants are looking so nice with that CO2. And now I want to replace my dwarf lily with a tiger lotus--so much more red. I also love the pearl scale on your angelfish. Hope they continue to get along. I have a pair in my 40 breeder display tank who just bred for the first time--it was the left-hand 20 gal for them, and the right-hand 20 gal for everyone else (cardinal tetras, lemon tetras, albino corys, panda garra). Of course, the eggs were quickly eaten. I might try saving some next time. That idea of taking out most of the hinge on your lid is smart--mine is right in the way of the light.
