Reefing newb
Ok so today i got home and my tank had a film on the glass and the rocks/sand were covered in a golden brown algae. My torch coral was still tucked in. My firefish is laying on his side barely breathing. My water test strip looked ok.. but my alkalinity looked a little low. My temp and dalt are ok. What could be wrong?? I did a quick 1.5g water change.
