I bought an Anubias lanceolata and noticed after a while that it was declining. I bought liquid fertilizer since I don't have CO2 and bought another Anubias to compare. Even though I fertilized the aquarium correctly, the old Anubias didn't improve and the new one started to decline. I'm also having an algae problem on my wood; it's a grayish algae, and a dark green filamentous algae has appeared on the plants. Could someone please help me? I'm lost.
