 My reef is dying
Hi,
I am a little desperate. I have kept a reef aquarium (80 gallons) for 3 years. Started slowly with well cured liverocks. Life emmerged everywhere: mushrooms,fireworms, feathers dusters worms grew to almost 2 inches in that time, have a green anemone, polyps...and a few fish (total of 6 : 3 damsels, 1 big yellow tang, flame angelfish and a blue girdle angel, and one hermit crab. All those for at least 2 years. Then suddenly (over the last month) the feather duster worms died, than the polyps remained closed on themself. Huge quantities of brown algae started to grow, the caulerpa even disappeared! I made a big change of water (2/3 of the aquarium 4 days ago) but nothing seems to work. The algae are growing as fast, the rocks are covered with a brownish velvet with bubbles and now my nice and expensive blue girdle angel looks pretty sick. The ammonia, nitrite and nitrate levels are all perfect (at least that what my testing kit is saying...), temperature as usual 26°C. Any suggestions?
