I'm new to saltwater- Two months tomorrow.
55 gallons (long) and no protein skimmer.
I have my 2 original yellow-tails.
I have two dominoes and one of two perculas purchased three-weeks ago.
For the past week the perculas have had a long, white spiderweb looking piece hanging out. The LFS
said it was "fiber" in the diet when I called asking about internal parasites.
Also for the past week, an incredible amount of brown algae (I guess) has spotted up the tank, though the water quality has stayed the same for weeks.
Yesterday one of the perculas, on its side, and gasping. It died today. The water quality was crazy. I did a 25% change and the situation now is:
The others remain normal.
I feed marine flakes twice daily (only what they can eat in five minutes).
Is that normal for percula feces?
Should I be worried about the brown gook?
Should I plan to dump more water SOON? I want that nitrate down!
