My tank got brown algea at first and it went away. Got hair algea and that went away thanks to the hermit crabs.
Now I got brown algea all over the tank.
Not so much on the rocks but on the substrate (aragonite) and espacislly on the glass. I scrub the glass before water changes but it gets all brown by the next day. I changed the poly filter 2 days ago
And it already turned light brown.
I added a skimmer yesterday. I'll remove one ac 50 since I have 2 running. What should I fill it besides poly filter?
What else should I do? Maybe add chemi pure blue? Purigen?
Can't wait till the skimmer is done breaking in.
The microbubbles are annoying.
