Can you guys tell me what kind of algae is that on the picture. As soon as my anubias make new leaf, the are being covered this blackish / reddish algae. And my cobambas seems to start having this problem as well.

It is a type of red algae, related to BBA but unlike BBA it has a low compact growth. It is hard to remove by scraping. It seems to also be mixed with GSA (green spot algae). Spot dosing excel or easy carbo on the leafs of the anubias will remove it. Cleaning up the tank (water changes, filtration, vacuuming ) will reduce new growth. It might also be receiving too much light for its metabolism.

I had a similar problem a while back. I had very dirty substrate, and my CO2 wasn’t stable throughout the day. You might want to give your gravel a deep vacuum and see what comes out. Judging by the first picture the substrate near the glass looks dirty, probably throughout the tank. Do the vacuuming in sections, uproot the plants, vacuum 20% of the substrate, then do a large water change. Maybe spread it out over a couple of weeks. Drop your light level a bit while you fix the buildup of organic waste in the substrate.

Still not close enough to really see what it is but from what I can make out it looks like BBA.
What are your tank parameters, tank size/capacity, lighting - photoperiod duration and intensity, filter turn over, circulation, CO2, fertz and water change regime, etc?
Can you post a full tank shot as well, it might also help solve any problems.
