endured 3 days of algae on glass which is now over. Replaced overnight with milky tank. One fish dead. another not doing well. Did 20% water change. Still cloudy. Is 20 gallon with protean skimmer and tank is about 2 months old. Placed earlier situation in the algae forum with pix and several comments. Only immediate solution seems to be to wait it out and see if it gets better or worse.
