Hey everyone! Wasn’t sure where to post this. I have a 20g nano reef that’s been fallow for 2.5 months- I did a 20% water change along with basic cleaning maybe 2 days ago. This morning I woke up, and my water is murky brown and my macro algae is melted and bleached. Corals are still open, even my BTA looks happy. Any ideas? I have an API test kit, so I’m going to my LFS today to have it tested.
