Hey Thor and guys, Sorry to miss out these questions. It's way too busy for me before the hollidays with work.
Anyway, in the last month, I started to try some Brightwell products like microbacter7 and bio-fueland (or vodka) and see some positive sight. Water is more clear and algea is decreasing a lot. I am also feeding the tank with zooplantos and phytoplankton. Some corals also started coloring up better.
