Ok, here are few images
For now, I did not notice any new growth of algae, everything looks clean. CO2 still seems to be problematic so i decided to add half of the Excel dose along with light CO2 injection. Back to the plants, most of the damage are on two leaves of Aponageton. One of the leaves is old, another is relatively new. Neither of them was grown in the current aquarium, so I guess there could be multiple version why is that happening. MTS picnic? Damage on Anubias is 1)circle-ish in nature, so far at one spot 2) undeveloped young leaves, I think was a consequence of algae, as they were covered with it, maybe something else? There is also something weird with M. Matogrossense, some of the stems are kind of translucent/pale while other are bright green. Not sure what is the cause of that.
