Could use your help with the following:
20g long (since 5/2010);
Marineland Penguin bio-filter system;
plastic plants / live plants / moss wall / driftwood;
11 fish / used to be ~25 RCS.
Just recently, black algae (long, hair-thin strands) started growing on the plastic plant, driftwood and one of the live plants. At the same time, the RCS started dieing off. Not sure if they are related?
Here's today's readings:
Temp = 78
Nitrate = 80
Nitrite = 0
GH = 150
Chrlorine = 0
KH = 40
Ph = 6.8.
I know the Nitrate is really high, but I don't know if it's the cause of the above AND / OR how to correct??
Your assistance / advice would be appreciated!
