Ugly phase help

grr410 · Mar 18, 2023

Hey everyone. My tank has been up and running now for about 3 months and it seems as though I am starting the ugly phase. My glass is getting ridiculously dirty every day and I have attached a pic of the algae forming.

my phosphates are .33 according to my Hanna checker and Nitrates are reading 0.

Any help on what to do would be great.

Although I never used to have problems at undetectable (not necessarily zero) nitrate, it seems now advisable to raise nitrates.
