I messed this up for a year, inconsistent or low C02 and not enough nutrients. Your journals really helped me, so I want to say thank you.CO2 is best kept at 30-40ppm, IMO, regardless of light! CO2 is often the bottleneck for our plant health in many cases (not all, just many).
A tank with high nutrients/aquasoil, medium light, and high CO2 is almost always a guaranteed success. Even low light + CO2 is excellent for our tanks.
