So like the title says i keep going through the same cycle... Dino to cyano to dino and repeat. This has been going on for two years now. I am having trouble with algae and understanding how to control it. I see dinos and see low nutrients raise the nutrients. Cyano and green hair algae come i let it take its course with just water changes careful not to bottom out nutrients and boom dinos start to creep back in and cyano and green hair die off and repeat. Any advice on how to control this disastrous cycle I am losing hope.
